OK I see what he did with the charger. It uses an adapter (host) cable to go from the main hub port to the PC (mini-USB to full size USB-A).

It looks like he spliced the micro-USB OTG cable (pin 4&5 shorted) to a mini-USB cable, and made a custom OTG Host cable. He mentions he disconnected/broke the +5v wire to prevent it charging the phone due to the small battery in it. I wouldn't do that myself, but I'd also ideally want a 3000-4000mah Solar Hub to modify for OTG & keeping the phone/tablet charged.

Have a look at my OTG cable schematics in reference post 9 above, particularly cable 1.

hi

so his phone supports data / charging at the same time?

but to mod an OTG cable for hptp and the mini usb port Hub, we just need to replace the usb end?

and leave pins 4 and 5 as they are?

How else would you make it instead..

I looked everywhere for a better self powered hub whether replaceable battery or not and would have liked to find something better.

thanx.. maybe I can try to make one
[TouchPad General] mpgrimm2:
From the OP

If you look through the first couple of posts in the tips & tricks thread, you will see how I modded a standard micro-Usb cable to be an OTG cable by adding a jumper between pins 4&5. (Cable schematic #1).

Yes, the Evo3D is able to charge with OTG enabled at the same time when powered externally. My HP TP will show an "charging" symbol over the battery icon in the status bar, and say "charging" on the lock screen; but when i go to "settings" -> "Battery" it shows as "discharging". My theory is that without the data pins shorted in the charger (OTG cable dependent) and a high enough output from a charger, it's actually discharging faster than it's being charged (with my Modified "Crazy On Digital" charger). If I come across any more micro-Usb cables to hack apart I may do some more testing with the actual HP 2A charger.

hi:

so S-trace (post #2 from http://xdaforums.com/showthread.php?t=1916638)

says that using just his bliss power bank, he can enable OTG on his phone and it will do data transfer...just using a regular non-OTG cable..

would this possibly mean that this type of charger would do data transfer using an OTG cable for HPTP and not need any mod to the charger?

he said that any charger that arranges the USB as ( - - ) rather than ( = )

should work

to mod a cable and use this type of charger would be epic for me if its really that simple

thanx for your patience..
[TouchPad General] mpgrimm2:
Have you looked at the Tips & Tricks Thread yet?

The Crazy On Digital charger I linked allows data to pass between the 2 ports without any modifications. Combined with a purchased OTG cable or adapter, you will be good to go on the TP. If you get the "AppleCable" OTG cable with Power port, it will work with ANY Charger, including the HP Touchpad's 2A unit. I have both setups and would recommend the Applecable one for easy use without any mods. The only reason I added a switch later to the CrazyOnDigital model, was to short the data pins and put a device into "AC Charging" mode before using OTG.

Also,

Didn't know OTG could be activated (on the Evo3D) using a standard cable with a sysfs command like:

echo host > /sys/kernel/debug/msm_otg/mode

Options are "host" or "none" (maybe this command can get added to "kernel Tuner" app! ). Wonder if it's the same for the TP.
[TouchPad General] mpgrimm2:
Here's something I realized today...

If I can get a hold of another USB Controller Board (to make it worthwhile to open it back up) I might have to throw in an Adafruit Solar Panel laminated to the back, either a Small 1W or a Large 3.7W since they are thinner and might follow the curve on the back.
[TouchPad General] amkaos:
i did go through the Tips & Tricks Thread

i did see the Crazy On Digital charger.. and the applecable..

i would just like to not be tied to the wall to use a hub.

also, if possible, ..and not really a Y setup..

i wanted to just have one straight cable to one hub.. its just cleaner..

thats why i got the solar self powered hub.. it just doesnt have much power..

but it works really good.

all in all, thats why i thought a 2 or port battery charger could be ideal if it could do data transfer..maybe it could charge when not used for data somehow.

thanx..
[TouchPad General] mpgrimm2:
I now understand. It does sound like a large solar backup battery with 2 full size ports is the way to go for you. You will need to open it up and make sure there are no resistors or shorts between the middle 2 pins ( d+ , d- ) so it can pass data.

[TouchPad General] amkaos:
couple questions :: would that let it handle both data and charging?

even if I need a modded cable?

l did see a charger 5600 mah for around 12 $... Also one that uses 2xAA, for under 10$.. I use 2600mah rechargeables; does that mean its still 2600mah or 5200?. both of these had at least 2 usb ports.

Once I buy one.. if I open, it's mine.. I would need to be confident it could do what I need to.. .. even if I needed different cables to charge / data.. somehow

thanx
[TouchPad General] mpgrimm2:
My impression is that most of the "apple compatible" chargers retain data functionality ( not shorted) like the CrazyOnDigital unit. It May be the same for the battery packs. It all depends on what u purchase and likely there isn't any way to know for sure until you crack it open, then its yours. If it will pass data b/w ports out of the box it should still charge at a Max of 500ma like a standard USB port.

To keep the thread cleaner, you can pm me links to anything you are considering and I will let u know what I think about the potential. If u r willing to cover shipping back & forth and are willing to risk the unit without any guarantee, I'm willing to crack open & mod it for the fun of it.

First ive heard of it.Cool.Hopefully it keeps the devs interested in it. All thanks to your concept Ften!

Do u know if its possible to "echo" a sysfs command on the CM9 Touchpad to enable OTG. I got the developer to add the Toggle to the kerneltuner App and it works on the Evo3D, but not on the TP. See the request here

I'm gonna have a busy holiday after all..!

Does anybody know where to get the original spare back cover for the TP, mine has the faulty one which broke after a few weeks, I dont think its gonna survive to this.

Thanks for your help.
[TouchPad General] mpgrimm2:
I will say that it would be easier to squeeze in a microUSB breakout board like Ften did on the original version without all the dremelling, but then you would need a cable adapter or make one.

I'm not sure what you mean by "spare" back cover, but it seems that the only way to get parts is through used items on ebay or a very limited number of resellers found via google searches.

I would love to see someone else succesfully do this. Good luck and hope you're up to it. Post or PM if you have any questions, I will answer any that I can.
[TouchPad General] glacket:
I was thinking about installing a microsd card breakout board based on your instructions. From what ive researched so far, the card slots have a voltage variance of 3.3 to 5v. So would i be able to skip the step up transformer and just connect the 2 data wires and 2 power wires from the 3.7v connections straight to the micro sd breakout board? I am wondering if i would need a controller as well or just the single breakout board?
[TouchPad General] mpgrimm2:
To be honest it sounds plausible with a controller board/microSD card read (not just a powered breakout) but I am not sure. I will say that over at Rootzwiki, AndroidLover, is an Electrical Engineer and is working on a single custom built usb board to go into the slot. He would be the person to ask. If you are unable to contact him, let me know and I will be the middle man if needed.
[TouchPad General] glacket:
When you connected the data wires do you just have the wires epoxied down and touching the traces or did you solder them to the traces? thanks!
[TouchPad General] mpgrimm2:
They are soldered down to the board. The epoxy is there as a strain relief; without it the wires will break off where soldered to the board (and likely damage the solder trace on the board).
[TouchPad General] glacket:
Cool. It was a little hard to tell if they were soldered. i usually dont see wires soldered directly to the traces. Thanks.

Using the existing port?

This got me thinking... is there any reason you didnt take the 5v+/- directly to the existing usb micro's 5v+/-?

Love the idea of the full size port... but if I already have an OTG adapter (micro to full) I was thinking about either finding a 5v rail (assuming Ill find one as most electronics/phone junk runs on 5v, or that's what I thought at least), or doing like you did and creating one with a step-up board.

Just curious why you did things the way you did
[TouchPad General] mpgrimm2:
This wasn't my original idea, it was [MENTION=2189671]ften[/MENTION] who came up with the regulator and port, I just added the full size port and data lines. Phones/tablets operate off of a 3.7v battery so u won't likely find a 5v rail easily which is why a step up circuit was needed. If you connect it directly to the existing micro port without additional circuitry you will "loop" the battery back into the charging circuit and drain the battery faster. I'm not an electrical engineer but that's my understanding.

Sent from my Up all Night Sleep all Day EVO3D!
[TouchPad General] spiffomatic64:
good point, I hadnt thought about it trying to charge itself... I understand they operating off a 3,7 batt... but I highly doubt they'd run electronics directly off 3,7... almost anything electronic I know of runs on either 3.3 or 5v, and even if it did run off 3.7 they'd want a regulator because the battery is gonna drop in volts as its loaded/drained.

Just brainstorming outloud now.. (im not an EE either but ive been getting more and more into making my own circuits/coding to avrs/arm and such) but Im thinking if I used a transistor(s) to detect when pin4/5 are jumped (otg) and sever the power to the tablet (so a normal usb cable to charge would still work) or if not possible with a transistor alone... use an attiny85 with a single transistor

Thoughts?

Hi can anyone help me, I turned off my phone off at night(battery 100%), and in the morning it will be 60%. It drained even though the phone is off. I am running CM10 M2, and franco kernel.

Could this be a ROM or KERNEL problem?

I did experience this when changing to JB. Was not happening in ICS. My standby battery was not very good as well. Around 5%/hr even it is just idle, but this I understand it might be caused by ROM/Kernel/Apps.

But I don't get if it's off. I know it's not the battery fault, because when it is unplugged, I leave it for a day, and it's still on the same level on the next day when I used it again. I don't think it is because the ROM/Kernel. I tried to search about it even on other forums, but still don't have answers. So I try to post this. Anyone having the same problem?

Thank you for any help!! Really appreciate it!

Hi,

I have a SGS2 with ICS. Recently there was an upgrade to ICS and Samsung Kies. After the upgrade, my device is not being recognized inn Kies or on my laptop.

In Kies, it detects the device but does not load its contents.

In Windows 7 Explorer, it shows the device, but when I try to access it, it throws an error "You do not have permission to access this device".

Other USB devices work fine.

I have tried the following:

- Restarting SGS2 and Laptop

- Re-installing Kies and also an earlier version of Kies

- Factory reset

Any help in this would be of great help since I am unable to access my phone from my laptop.

Are there any other methods to back-up Phone contents on laptop?

After spending an hour modding my OG atrix lapdock to work wth my Atrix 2 with the specific purpose of being able to plug in a mouse and keyboard or controller to play Shadowgun: Dead Zone... I've discovered two things

1. or whatever reason the Lapdock's USB ports are not read by USB/BT Joy Center - so i cannot use the gamepad to touch mapping function

2. The Lapdock keyboard is being detected as a gamepad - having a game pad present disables touch in shadowgun games... so i can't even use the native mouse to spawn and THEN plug in my gamepad to play.

Does anyone have a solution for this other than getting a PS3 controller to map with Blue tooth? lol I dont have a ps3 I have a 360

Just because your question isn't answered doesn't mean that it is ignored. It may simply be that there are not any other people who have attempted to do what your doing here... the Atrix 2 community is a relatively small one on XDA. I would try post in the Atrix 4G forums, the original atrix functioned the same way with shadowgun and the lapdock... perhaps someone there will be able to help you
[Motorola Atrix 2] CapnPez:
I'm not sure if this will work the way you want, but perhaps you could only plug in the hdmi cable and leave the usb port disconnected. Then, attach a usb otg adapter or cable to run your controller. This would require dangling wires because you wouldn't be able to dock it anymore since you would need access to both ports. Or, you might be able to make a little pigtail with the usb cable out of the docking area and to an otg adapter/cable.

Sorry, I don't know enough of the software end to know how to disable the keyboard and get what you want. You could potentially disconnect the hardware of the keyboard/touchpad and then you would essentially have an hdmi monitor and two usb ports.

Good luck!
[Motorola Atrix 2] Washburned:
Actually have the same problem with that game, although mine was a usb controller for pc.

The bright side is that the old Shadowgun actually does works pretty good with the same controller, maybe the guys from Madfinger would apply it later to DZ.

EDIT: Shadowgun DZ had an update, where they included gamepad support.

But it's still buggy with lapdock, you have to chose NOT to detect HDMI cable (in display settings) before you connect the phone to the lapdock, connect your gamepad and use your phone display to play.

I'm sure there is a way to overcome that thing.

My upgrade comes next month and I wanna hear from those who switched from the og note to the note 2. Was it worth it to you? How is the phone performance? How about development? I've been watching this forum closely and I look forward to any input you might have. Thanks in advance.
[AT&T Samsung Galaxy Note II] Rinwashere:
I went from the HTC Desire HD to the Samsung Galaxy SII, and now, to the Samsung Note II.

The size takes a bit getting used to. I'm still trying to use the back button with my left thumb, which just can't reach across. I have tiny hands. But other than that, I love the screen when I'm watching or reading something. The S-Pen adds a totally new dimension that I didn't expect before. I don't mean just the handwriting recognition or being able to get your cursor where you want. Being able to do screenshots, crop and annotate them is super useful, at least to me.

Aside from that, performance is what i'd expect from a brand new phone; everything is snappy and smooth. The battery lasts me the whole day (8am to when I sleep, 11pm or so?) rather than just half a day (have to charge before I leave work). I consider myself a moderate to high user: I've used 5gb out of 6gb of my quota (around 1gb for google reader alone), but most of it was for tethering.

The Samsung stock keyboard was surprisingly useful. They snuck in that word prediction feature from Swiftkey (well, i bought swiftkey from before) and it's finally took me away from the compact qwerty layout I've been using since the first Blackberry Pearl (2006).

Lots of little Samsung'isms all over the place. Little tilt motion things, not turning off when you're reading, keeping orientation when you lie down in bed while reading ... it's useful!

Things I'm not impressed with:

Not enough S-Pen specific apps. Not really Samsung's fault, I know they've been trying to motivate developers

Screen is too bright sometimes in the dark. I think it might be me not figuring out how to set it yet

Size. Both its strength and its weakness.

TouchWiz. Okay, this is personal preference for sure. But I replaced this with one of the many 3rd party launchers available, so it's okay.

Language Support, in particular East Asian language handwriting recognition support. Again, 3rd party. Most people won't need this, I'm guessing.

Not being able to save apps to the SD card. I don't know why, But I haven't been able to find the function. I only got the 16gb one, so I'm scared it's going to fill up.

That's all I can think of right now.

A console which would probably not sell so well after we upgrade our just as powerful smartphones after 2 years and use them as a console instead. Whatever the reasons it is bad for us, bad for developers, bad for android and bad for sd card makers. The funny thing is that Samsung boasts about the expandable storage!!
