I'm not 100% so I could be wrong, but I don't think it's possible. By the way the OTG adapter seems to work you have the choice of USB functions or charging. you have to power off the device and plug in the OTG adapter then power it back on to get it to work, and once you unplug it and plug the data/charge cable back in it turns off OTG functions and you have to reboot again. I know the data/charge adapters and the OTG adapters are wired differently (that's how the OTG adapter enables USB function on boot if plugged in) so you could try taking apart both adapters and combining the pin connections of the two. I'm almost positive this won't work though. Plus if it did I'd imagine we'd already see them available just like the OTG adapter.

[Dell Streak 7] TheManii:
If you want to both charge and use otg you need an official dock as that's the only one with all the pins exposed (as in available to the user).

I'll have to (re)check, but I believe it can both charge and accept otg devices.

Dock charging is serviced by different pins then the normal usb charge. afaik only the official dock has an otg port, generic docks dont.

It might be possible to hack a cable to do both, but the sold ones are not wired to do this by default.
[Dell Streak 7] zenisnotchosen:
The dock will not support OTG without modification though (maybe that's what you meant). I've tried without modifying the wiring and it will not enable OTG.

Sent from my Streak 7 using witchcraft
[Dell Streak 7] TheManii:
My 2nd gen dock does without modification, you are using the actual OTG port correct? And you're providing power right? The S7 will not provide power period.

Of course it requires using a custom rom as the stock rom doesnt support OTG.

I've been able to use otg and hdmi out on my tv simultaniously, I dont recall if it can charge but otg definitely works.
[Dell Streak 7] zenisnotchosen:
My dock only has the mini USB data port, HDMI port, 3.5mm audio jack, and power port. The mini USB port does not work for OTG. Maybe it's because my dock isn't second gen though, I don't know if it's first or second gen. Yes the stock kernel does support OTG. I have stock 3.2 and OTG works perfectly with the OTG adapter.

[Dell Streak 7] TheManii:
As far as I'm aware:

Gen 1: Designed for S5

Gen 2: Designed for S5 and S7

And both contain the following ports:

Dock power connector

USB-OTG (usb mini-AB female)

USB-Slave (usb mini-b female)

Line out

Speaker out

(see wikipedia for usb port definitions)

I have not heard of a version not containing both usb ports.

I personally have a 2nd gen dock and I believe that my info is correct for the 1st gen dock.

Could you provide pictures of the dock/original box? By what you're saying it's an official dock from dell I assume?
[Dell Streak 7] zenisnotchosen:
Yes official dock. Only one mini USB port. it supports both Streak 5 and Streak 7, it has both clear plastic pieces that support the phone/tablet standing. Came with Dell AC USB power adapter, Dell mini USB to USB make cable, and Dell power cable (barrel plug to male USB).

[Dell Streak 7] TheManii:
Whoops! my memory was playing tricks with me, it only has one port.

But we have the same dock, that's the 2nd gen dell dock.

As I said though, you can do otg though that dock as long as

you have a rom that supports otg (stock roms do not)

you have a powered usb hub (as the S7 does not supply power)

an approporate cable

The 2nd gen dock (and I believe the 1st gen also) has a micro usb-AB port, and not the standard micro-usb B port.

It's one of the few devices fully in-spec for usb-otg. (nearly all devices are out of spec in that they use have a micro-uub A female port and yet support otg, otg devices were always supposed to use micro-usb AB female ports, but micro-usb A is depreciated now)

You're 'supposed' to use one of these:

To properly use otg, but you can functionally get away with using a Mini-A male <-> Standard-A female.

This is what I used and I can confirm it works as long as you meet all 3 requirements up above.

I'm not sure how important it us to use a Mini-A male <-> standard-a female instead of the more common mini-B male <-> standard-a female.

If you dont supply your own power, the S7 will simply not detect anything at all.

Even with a powered hub it took a lot of fiddling with it to get it to initialize the hub (hub turns on if it detects a host, and it took much time to get it to power up).

I can only confirm that a keyboard and mouse work though, none of the roms are set up to accept drives (mostly config issue, not inherently unable to).

Edit: I had already dicussed this in a previous thread, repost:
[Dell Streak 7] zenisnotchosen:
I tried using mini USB to female USB and using a gender changer on a mini USB to USB male cable and it doesn't work for me. I wish it would. And my stock ROM does support OTG. I can use it fine with my standard OTG adapter.

[Dell Streak 7] TheManii:
Which rom are you using exactly?

I dont remember how much testing I did on stock roms, I spent most of it testing on ICS (i think?, it was months ago)
[Dell Streak 7] zenisnotchosen:
Dell official Honeycomb 3.2 514 21700 if I remember correctly. It also worked on 503 19535 which is what my Streak 7 came with preinstalled. And thanks for trying to help.

[Dell Streak 7] kwadhwa:
I have recently got myself the Dell Official HOME Dock for my Streak 7 (4g version, Stock HC, rooted). I also have a "mini USB male to USB female" like the one you have shown. I tried connecting my Flash drive using these, but obviously it would not work.

So I wanted to understand:

What custom ROMs support OTG?

What exactly do you mean when you say a "powered usb hub"? Do you mean I need a USB "Y" cable and have one male connected to the power?
[Dell Streak 7] zenisnotchosen:
Yes, use a Y cable with one end plugged into USB AC adapter. The Manni said he has been successful using the dock that way but I have not. I can only use the standard OTG adapter. Stock ROMs DO support OTG, the dock just doesn't in my experience. I'm using OTG currently on stock Dell ROM.

Also when using the OTG adapter you HAVE to turn off the Streak, plug in the OTG adapter, then turn the Streak back on with it plugged in to enable OTG function. I also use two apps that are helpful with checking that USB is functioning and for auto-mounting flash drives. They are USB Host Controller and USB Mass Storage Watcher, respectively. You can find them in the Play Store.

[Galaxy S I9000 Q&A, Help & Troubleshooting] Rob014:
Hi,

I was running cm9 successfully for about 2 months, I would get occasions where the screen would go black and unresponsive. I had to pull the battery and reboot and it would be fine. I thought this was fairly normal for a cm9 nightly as it didn't happen very often. A few days ago this happened to me, and upon pulling the battery and rebooting, the phone just went into bootloops. I could not access cwm, so had to flash JW5 via odin, rooted it and attempted to flash cm9 again, this too results in bootloops.

Can anybody help? Being stuck with Samsung firmware is such a regression after having used cm9.

I've tried the same 2.3.6 firmware i installed with an older cm9 nightly which i know worked when i flashed it but get the same results.

Help me please.

Rob.

I had this problem too. First, you don't need to remove battery, holding the Power-button will restart your phone even if it hangs. I never got the data back after the boot-loops. I recommend using titanium backup, I have it set to backup all my data every second night, so I can keep almost all my application data even if the nightly was bad.

[Nexus 7 Q&A, Help & Troubleshooting] carnagecjb:
Off the top of my head, the cables listed won't work as-is.

USB OTG is a male micro plug to female USB receptacle.

The Y cables have the requisite 2 male ends and one female, but they are connected wrong.

(I own several different ones, and they are all wired the same way, so I'm assuming that will be the case for a majority of these types of cables...)

These are desired to draw data & power from one of the male plugs, as well as drawing power from the second male plug. The female plug receives the data and the increased power from the second plug.

You would need a cable that actually has a male where those have female, and replaces the existing data/power male with a female.

(The more times I read that, the less sense it makes to me, so please let me know if more clarification is needed...)
[Nexus 7 Q&A, Help & Troubleshooting] RED ZMAN:

i use the y-cable+power setup for my kindle fire because the usb port doesn't supply enough power, all it does is provide enough to power the device so the KF can read it

I remember the problem with xperia arc before that using usb otg y-cable does not charge the phone. I even made one myself. It must have been the standard usb spec not to accept voltage in vbus when in host mode. But the xperia dock can charge and usb host at the same time. There is some sort of circuitry inside but none has posted a disassembly yet. I am guessing the current might have been pulsed via pwm.

My cheap china tablet won't do both either. It has two usb ports but only one hosts (but not charging), the other guests and charges.

The samsung has a proprietary port with many pins so it is irrelevant.
