content: Looking for a way to extend a USB connection wirelessly, quick search around found plenty of USB to WiFi network and USB to Bluetooth speakers etc but that's not what we are trying to do.What we want to do is connect a laptop to a piece of test gear like a power supply (has a standard printer type USB port) for remote control of voltage and output on/off. Very low bandwidth stuff, probably using a virtual COM port. Both ends supply 5V (a USB isolator works fine) so we don't need to transmit DC supply, just need communications between the PC and the device.For OHS reasons (high voltage / temperatures) and to save the need to run a physical cable to the laptop I would like to do this wirelessly. Something like a USB dongle in the laptop and another in the power supply that can between them communicate over a short distance, about 3 to 5 metres would be plenty enough. Doesn't need to be secure, it's only sending numbers. There is no WiFi available / allowed in the area where this will be set up.Anyone know of or can recommend a way to do this? Would like something basically plug and play, suitable for electricians to operate, so no raspberry pi with custom electronics / coding or similar.

content: We use device servers from SEH Computertechnik for various devices. It essentially puts USB devices on your network, which you simply connect to over IP. This would also allow you to share your device across as many computers as you like (albeit, not at the same time). The client software runs on Windows, Mac and Linux.https://www.seh-technology.com/products/usb-deviceserver.htmlWe primarily use them for things like label printers, but also for software that require a physical hardware dongle. The dongles can be connected to the device server and locked away in a rack, so that they are not only accessible to those on the network, but ensures the dongles don't go missing.Once you connect to a device, it just presents to the operating system the same way as if you would have physically connected it with a cable.

content: Hi,can anybody list some good websites to refer to when selecting my new SSD drive for this HP system. The current SSD is a 256GB, Samsung SM951 NVMe, and I'm looking to upgrade it to either the 512GB or 1TB variant.The Crucial/Micron system scanner doesn't work, as this is not a mainstream computer.Here are some more technical details on my current drive setup:P/N: MZVPV256HDGL-000H1Model: MZ-VPV2560HP P/N: 801075-002Standard: NVM Express 1.0/1.1 ??HP Z Turbo Drive (G2)PCIe 3.0 x 4MSIP-REM-SEC-MZ-HPV2560 (not sure what this number means !)It would be great if I could find an NMVe that's a qualified part (on the AML list), if not, something compatible & reliable would do.Any advice?

content: Yes, there should be no limit in size, and PCIe3 is likely the best you could have, so unfortunately no super fast "modern" ones (at least there are no major speed benefits when using them).The 951 is an OEM model, with no end user support (though HP, Dell etc. might roll out patches themselves); for the newer SSD I suggest to go with an "official" part, with customer support. Anything from a major brand will be fine.

Running them at up to 100 C is no problem at all.The problem is that the voltage settings for the highest turbo speeds were set incorrectly from the factory, and were causing something like sparks or burnout at the microscopic level.There are lower voltages that are safe but are still sufficient for those highest clock speeds, and updated chips use those voltages.

content: All Raptor Lake systems have BIOS patches available at this point, AFAIK, so they are OK if they've been updated.The real problem is that any degradation that occurred prior to the BIOS update is permanent. So while there is no reason to avoid new CPUs, existing ones may end up with curtailed operating lifetimes. I have a 13900k that couldn't runy-cruncherfor more than an hour or so, and that's still the case after upgrading.

content: Hello, so, my father has become very into using VPNs for everything and is now thinking about buying a router with VPN client support to have every device on the network use the VPN he pays for. some of the sites and apps i use block VPN IPs, and so I would like for my devices to NOT use the VPN.On the TP-Link website, there's an emulator thing for most routers, and the AX55 V4 has a Device List section under the VPN client settings and it looks like there's a way to turn off VPN access for specific devices. However, when looking around for routers that support that(selective VPN usage on specific devices) the AX55 isn't listed, and the various robots (chatgpt et al) say it does not.So i'm asking anyone who owns this specific router if they can try to do that and confirm that it actually works that way(allows you to select which devices will connect through the VPN, and which ones won't)I don't care if there are ways to bypass the VPN IP blocks, or if anyone thinks that shouldn't matter. I want to have confirmation of if this router does what i want it to do, or if it doesn't.Thank you!

content: What you're talking about is generically known as "policy-based routing". What VPN protocol is it you want to use? Before you go out and buy a new router, you might want to consider that OpenWRT, FreshTomato and DD-WRT free, open source router firmware all support VPN protocols, such as OpenVPN and Wireguard. You might want to look into those.If you do decide to buy a new router, what you're looking for (if you need to speak with clueless salespeople) is whether certain traffic/clients can be routed normally, instead of through the VPN tunnel.
How and when the TRIM command works with Samsung SSD drives - Page 1

content: Hello,A few days ago, I sent all the data from an SSD drive that I was running in RAID1 mode on the ICY-Box hardware base on the Mac OS to nirvana. Nothing bad happened electrically. I wanted to install a second RAID1 system using the switch settings of the existing system as a guide. I mixed up the USB plugs and “treated” the existing RAID1 system a second time with the RAID Assistant of the MacOS hard disk utility. As I understand it, not much should have happened, but the result is that the previous data can no longer be accessed. The RAID1 system consists of ICY-Box + 2 SSD disks from Samsung SSD 870 QVO 2TB.Now I just have this question: Is it correct that the SSD drives are deleted independently by the internal TRIM command of the SSD drive as soon as it is started by RAID Assistant of the MacOS Disk Utility. And now comes the second question: Is knowledge of the existence and functionality part of the basic knowledge of a technician who deals with data recovery?

Maybe you'll get a slight increase in noise.Once you reach a certain point with USB cables (3m+), certain products will randomly stop working, and you'll have to go active.

It would help if they provided info on exactly what config (drivers, etc) they build to, but maybe that's available somewhere. It makes me curious how it relates to my 14900K desktop.From the spec (clocks, etc) it looks like the 6 Series possibly has simplified P cores intended to run mostly in some sort of E mode. This would make a lot of sense as the power and footprint budgets are favorable (more perf/W, more perf/mm2).500W sounds like a lot, but the multi-die surface is huge so can probably comfortably be air cooled (kind of a necessity in a 4U rack unit).

And that's a kernel from February 2016!My i7-13900HX laptop, which I paid about US$1750 for, takes 1m15s to do a defconfig x86_64 build of the current HEAD as of today.So that would be 48 compiles/hour if I did them strictly sequentially, but there are periods of 7-8 seconds at the start and end of the build when there is only 1 or 2 cores active, so if you overlapped the builds it might be closer to 60 compiles/hour.I checked out v4.4 but using current gcc etc the build errors out almost instantly. So I don't know what parameters they are using for their Linux kernel build benchmark.Just over twice the performance from $36,000 worth of CPU (plus RAM, disks, PS, case etc) vs a laptop that cost 1/20th as much doesn't seem like good value, so I'm not sure what I'm missing here?

content: Quote from: Phil1977 on September 05, 2024, 10:17:34 amThe short answer is yes, unless it's a root hub.USB 3 SuperSpeed connection has both 5Gbps SS and 480Mbps HS wiring compatible with USB 2.0, and they are on physically separate wires.A USB 3 hub has both an SS and an HS hub. All the HS (and FS & LS) traffic goes over the HS hub, and all the SS traffic goes over the SS hub.HS traffic is not "upgraded" or translated to SS traffic.This is unlike an HS hub that will translate FS and LS traffic to HS traffic using one or more transaction translator(s), or TT.A common problem with most HS hubs is that they only have one TT, so can't aggregate total FS bandwidth over 11Mbps. A multi TT USB HS hub will, though they're rarely advertised as such.Conversely, it is fairly common for USB SS hubs to have multiple TTs that allow aggregating total FS bandwidth to over 11Mbps but that will still be be carried over the HS wiring.QuoteTypically not, althoughthis oneseems to claim to "The Multiple Transaction Translator (MTT) design prevents speed limitations, enabling multiple high bandwidth devices to operate at SuperSpeed."I would be sceptical though, as the terminology "TT" is a USB HS thing, not typically associated with USB SS.QuoteVL670 or VL671 chips will convert a USB HS device into a USB SS device.

content: It also says "Multiple Transaction Translator (MTT) design prevents data rate bottlenecks when legacy USB devices are attached".So dunno, but it's probably exactly what the name implies: a multi-TT hub, so your multiple keyboards and mice will enjoy a combined 480Mbps BW.There is no HS-SS translation in the spec and so such thing as SS TTs, so no particular software support for it either. A hub with multiple HS ports on SS bus would need to handle all protocol differences transparently and pretend at least to some extent that the devices are SS.Note that there is some mechanism (forgot its name) for aggregating two 5G devices on a 10G hub.

But the thing alreadyknowsthere is a CD present because it began running the setup program.Can't get past this.

content: You are complaining about Windows XP setup program, not VB itself.It's been ages since I used Windows, but IIRC, the Windows setup program doesn't actually know if the CD is inserted, because early in the boot process it is wholly loaded into RAM together with a miniature Windows environment which supports it, at which point you could pull out the CD and it will continue running in RAM. Then it needs to search for the Windows CD again (among all drives that may be present in the machine) and it asks to ensure that the CD is still present.

content: I want to do a fresh Linux install on my main PC but not disturb it until the last moment. I have a second PC that I can plug the new SSD into and set everything up on that, then hopefully transfer the SSD to the main PC.The main PC is an i5 with nvidia 660 graphics card and the secondary PC is an i3 with onboard graphics. If I just swap the drive from one to the other I expect it will run, but will Linux sort out the differences and automatically make whatever alterations it needs to do to run optimally? Would it end up being as good as if I installed Linux using the main PC, or would there be some shortcomings?

content: In some distributions drivers for GPUs may come in separate packages, so installing on NVIDIA may not get you AMD drivers and so on.Another potential issue is initramfs, which needs to be regenerated on new hardware sometimes or the system won't boot. But you will usually also get a "fallback" initramfs which contains lots of drivers and should work just about everywhere.Generally, hardware is autodetected on every bootup and drivers are loaded automatically, if available. You can generally replace hardware and move disks between machines, it's not Windows

The M.2 A+E only has 3.3V available (on pins 2, 4, 72, 74). You could easily add a Microchip USB251xB USB 2.0 hub to the card to extend the number of USB ports; see thePCB Layout Guide for USB251xBic's. JLCPCB even has USB2514B-AEZC-TR (4-port) in stock for assembly for $1.5 apiece, so you could have these fully made for you.Otherwise, try adding "NGFF" to your search terms as an alias for M.2. That way, you'll find stuff like theM.2 A+E USB 2.0 dual-port hub. I am a bit suspicious about EMI and EMC noise from their 3.3V to 5V boost converters, though.

content: By the sounds of it, this is some kind of old or obscure system? ATA passwords have been a standard part of most BIOS's for quite a while.That being said, what's your objective? Is the main point to secure the data on the drive? If so, ATA passwords are terrible and easily crackable/bypassed (for the most part).You might want to look at something like full disk encryption offered by TrueCrypt/VeraCrypt instead. It doesn't need any BIOS support.

On non-encrypted disks data recovery services can bypass the password.I seem to recall that there was some software for unlocking disks at boot time, intended for BIOSes with missing or limited password support (for example, not working with passwords longer than 10 characters) but I don't remember what it was.The important part is unlocking the disk. Setting the password can be done separately under a normal OS, you don't need BIOS support for that.

content: I'm having trouble sharing hard drives between an SSD running Windows 7 and another SSD running Windows 10. I have one SSD running W7, one SSD running W10, and three hard drives for data.When I first boot into Windows 7 or Windows 10 everything goes fine. The problem is that after starting with Windows 10, if I turn off and start with Windows 7 it gives me problem messages on all the hard drives, it gives me the option to continue with a check, I assume it will do a CHKDSK. I can skip these checks by pressing any key, but that will not prevent those messages from appearing again every time I boot, and the worst thing is that I can no longer make a backup of Windows 7 because it tells me that the destination hard drives are damaged and need a check.I don't know what happens that when starting with Windows 10 it leaves all the hard drives in a state that later when starting with Windows 7 it detects that they have problems or damages, when in reality all the hard drives are perfectly fine and chkdsk does not detect any errors.Right now I have both W7 and W10 on separate hard drives, because little by little I will move to W10 installing everything I have on W7, that is why I cannot make an immediate change by removing the SSD with Windows7.Is there a way to prevent this from happening?.

Rather, most of the default options hibernates Windows, which means that disks aren't going to dismount cleanly first (so that they are ready for use again when the machine wakes up).Test this theory. In a command line, issue the command:shutdown /s /t 0
