Ask Slashdot: Fixing UVC Camera Issues Under Windows?
Khyber writes: I bought some cheap Chinese camera glasses with built-in microphones. These are (supposedly) UVC cameras manufactured in 2015. Under Windows XP, these cameras are seen perfectly fine and work as web cameras; even the microphones work. Under Windows 7, the camera appears to install just fine, however I get the 'This device can perform faster if you connect to USB 2.0' (which it is connected to) and when I try to load it up with any camera viewer such as manycam or any chat program's built-in previewer, I cannot receive any video from the camera. I can get audio from the camera microphones under Windows 7, so I am wondering if the camera device is having problems enumerating as a USB 2.0 device due to some change in Windows 7 (which it doesn't seem to have issues doing under XP,) or if the UVC driver for Windows 7 is missing something in comparison to the one used for Windows XP. Anybody else had issues getting newer UVC cameras to work in newer operating systems?
I don't think that technical support for your driver issue is a good reason to post on /.
You must be running Linux, why don't you just be safe and come back to Microsoft, all hardware vendors make sure that their kit works with Microsoft Windows. Oh, wait .....
Now with more tech support!
Since when did slashdot become a desktop support forum?
cheap Chinese
there's your problem...
Which has more power: the hammer, or the anvil?
I've gotten this a lot with devices besides cameras (eg. an LG G3 phone), even when plugged into a 3.0 port. It seems to be caused only by devices with a standard micro-USB connector, not a full-sized one. My thought is that the device's USB chip is 3.0-capable, but the connector and/or cable don't have the extra pins/wires for 3.0 so the device is reporting itself as 3.0 but can only run as 2.0 which makes Windows complain. I haven't seen any problems because of it, even under Windows (I normally connect the devices to Linux machines).
yes this forum is totally windows tech support I just hope your post feels welcome
User wants help with cheap USB camera off ebay, only works in Microsoft Windows XP. Results in a wordy plea for tech support. This must be a new low.
have you tried running the consumption (camera) apps in XP compatibility mode?
Windows has 100% perfect driver support and supports all hardware ever made. You're not actually using Windows, you're using Linux, which can't even install a hard drive without recompiling the kernel.
Once you get the right cable you won't have to worry about your camera issues anymore!
I am Slashdot. Are you Slashdot as well?
You're probably going to have better luck at one of Reddit's tech support forums.
get the hardware id's from device manager, and check www.pcidatabase.com
Now I sit here broken hearted
came for an insightful comment,
yet found only fartheads.
and to remain true, hardware standards and software implementations, they're crappy. We do not live in a utopia, so people complain, and even less gets fixed so we have more to complain about.
It would be nice if all the hardware that was sold came with the schematics, specifications and programming/interfacing documentation.
That way the terrorists would be able to make their own nuclear veapons, and nuke us all from orbit, whilst sitting in their lunar base, sipping their earl-grey tea.
have a nice day.
ssssht!
You buy crap at el cheapo and then whine because they're not supported? Slash your wrists with a razor, stab your throat with a broken bottle, set yourself on fire, drink paraquat, just remove yourself from existence, you stupid shit.
By not posting stupid tech-support questions... some random guy's hare-brained scheme... or pseudo-science that isn't backed up by common sense.
You need a the right usb cable.
You will have to import the cable if you are not in the united states.

Fuck you, Khyber. Fuck you very much. Go post your tech support requests somewhere else, douchebag.
Also, where did you get the idea that Slashdot was your personal tech support forum? Give us a valid credit card number and maybe we'll do something for you, buddy, otherwise suck it up and figure it out yourself like the rest of us do.
Dude in 2015 you bought a device that only works on an unsupported 15 year old obsolete and now dangerous OS for internet streaming??! Seriously
If the camera was from the XP era I could understand. If you want to keep it then get an ancient XP box and DMZ the LAN behind a firewall to prevent internet access. But if you purchased this to use over the internet then the manufacturer gave you a shoddy and liable product that is negligent.

Actually no, not welcome. I'll bet there are some great Windows tech support related sites out there. Maybe start here:
https://technet.microsoft.com/...
Or more likely here:
https://www.google.com/
So there's your advice.
I was going to take the opportunity to launch into a full tech-support monologue but it brought back too many old and bad memories.

By using let me google that for you.

If that doesn't work maybe someone has a GeoCities site about this issue.
In these parts, 'Khyber' is CRS for 'arse'. Also on /. it would seem.
use a usb hub with nothing else plugged into it

I wonder if there's an inverse version of shibboleet that would be helpful when newbies ask for support in knowledgeable forums.

Barring the argument that Slashdot is not your personal tech support site, there's literally nothing to go on in your description. What's the manufacturer and model of these cameras? Are you using the drivers provided by the manufacturer, or did you rely on plug 'n' pray to find a driver for you and just use whatever it found? Do other devices in that port function as expected (correct speed)?
If you didn't explicitly install USB 2.0 and 3.0 drivers from the CD that came with your motherboard, then windows 7 will recognize it is USB 2.0 and 3.0 but won't actually allow you to run it.
Can anyone help me get this WinModem working under linux?
32bit Windows version might have a bit better luck, you might try running an XP driver under 7 32bit although playing with the USB stack or an on-board USB controller in that way may be ugly or bork things horribly.
Windows 10 probably fixes this.
I'd just go ahead and upgrade if I were you.
Couldn't hurt...
I went back through the archives to read Roland Piquepalle's last 50 posts to cleanse my brain from this level of Zika virus induced retardedness.
Trolling is a art,
I've had similar issues with flash drives. I'm one of those nerds who like to load external hubs with older flash drives and thrash them until they die. Thing is, they all need power. USB2 spec is 0.5A per port, but if you're running a passive hub off one port, each port on that hub has to share the power available. Eight hub ports splitting that half an amp can get a bit tricky, especially on USB2. Usually what happens is it hits a low threshold and drops to USB1.1 which requires less power to run.
On the same subject, Win7 seems to be a bit broken when it comes to USB power management (device sleep/standby), I have external hard drives randomly go into standby mode (it's irregular and unpredictable) which occasionally results in bugchecks.

...and will fail 64 bit versions.
I have a couple of older video capture card that won't work under 64 bit, either xp or 7.
Both work fine in 32 bit.
The only other thing I could suggest is a utility to switch the usb mode, or force a different speed.
Making a custom Linux or XP virtual session might be easier to do.
Good luck!

turning it off and on again?
You actually did a decent job. I hadn't had much coffee when I wrote that.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
User Grog6 noted that it would likely work in 32-bit Windows 7 and fail to work entirely under 64-bit Windows 7.
This ends up being correct. There is something off between the 32-bit and 64-bit usbvideo files that makes this particular set of camera glasses not function 100% under 64-bit Windows.
Now for the fun part: figuring out whether or not the difference is so drastic that I can't hack in the missing code, and whether or not I can fake the Microsoft driver signature so WFP doesn't flip its lid (and I'm not going to turn WFP off, sorry!)

Maybe you should upgrade to Windows 10.
XP camera drivers are typically VFW (Video for Windows) based, meaning that the camera talks directly to the video for windows interface. Later camera drivers typically piggyback on the Directshow interface and offer input pins which are configured from within the Source and Format dialogs. One single Directshow interface typically talks to the VFW interface.
If your Directshow drivers aren't behaving, look at the Format and Source dialogs and see about setting the resolution and bit format to something widely compatible (ie: 320x240, RGB24).
If that doesn't work, download a VFW driver like ManyCam and let it figure out the best settings.

It is funny if it was any other OS, we would not be having this talk.
Than there are the idiots that will defend the OS for dropping any legacy drivers.
That is why I will just say move on to another OS.
But since you are not here, what you can do.
If you want to use this crap of an OS, use Yaw cam http://www.yawcam.com
This will at least let you use any camera, for any use that you may please.
And to the other imbeciles why brag of what you know not.
If it is not a point and click it will never work for you.
This speaks highly of how much you do know, and is expected of you.
...who are complaining that Khyber's question/post is stupid, etc -- YOU ARE THE PROBLEM,
*NOT* KHYBER. Slashdot used to be a valuable resource for questions like this. Try and Contribute something useful to the discussion IF you have any knowledge worth sharing, or feel free to go elsewhere and post your useless whinging somewhere else. This falls under "Stuff that matters."
--Even tho I don't have any skin in this game, I learned something useful reading the responses that actually tried to help the guy with his situation - i.e. Win32 works, Win64 doesn't. Linux works. THAT ALONE makes it worth the submission, so GTFO if you don't like it.
