I just obtained a new (special-purpose) webcam, and it doesn't seem to
work at all. On kernel torvals/linux.git next branch, it doesn't even
really connect, on 3.13 (which I'm running on my laptop) I get errors
like this:
xhci_hcd 0000:00:14.0: ERROR Transfer event TRB DMA ptr not part of
current TD
when running uvccapture. When running e.g. cheese or the like, the
screen stays blank. uvccapture also reports:
ioctl querycontrol error 22
and then the kernel message repeats forever, while I can't even exit
uvccapture unless I kill it hard, at which point I get
xhci_hcd 0000:00:14.0: Signal while waiting for configure endpoint command
usb 1-3.4.4.3: Not enough bandwidth for altsetting 0
from the kernel.
The device really is detected as UVC, of course:

(see also full lsusb below)
I see a device from the same manufacturer has a kernel driver as a
vendor device but actually being UVC, but this one reports being UVC and
doesn't really work.
Any thoughts? Just to rule out hardware defects I connected it to my
windows 7 work machine and it works fine without even installing a
driver.
I can arrange remote access to the device (maybe as a VM to be able to
experiment with the kernel more easily?) if anyone wants it.

This looks like low-level USB issues, CC'ing the linux-usb mailing list.

Could you try connecting it to an EHCI controller instead of XHCI on a Linux
machine ?

Indeed, that works! Interestingly, it works neither on a USB3 port
directly, nor on a USB2 hub behind the USB3 port.
Thanks,

I would thus be tempted to classify this as an XHCI controller issue. linux-
usb should be the right list to get help. I've CC'ed Mathias Nyman, the XHCI
maintainer.
Johannes, could you enable USB debugging in the linus/master kernel and
provide a kernel log ?

Yeah, I tend to agree.

Sure. Note that linus/next is having even more issues with this device,
to the point where I couldn't even get the lsusb I pasted into the first
email. I used 3.13 (because I had it installed on the system in
question) to get that.
It was also throwing an autosuspend warning:
http://mid.gmane.org/1402177014.8442.1.camel@jlt4.sipsolutions.net
I'll try to get some logs (wasn't there tracing added to xhci too? will
check)

Here we go - log + tracing:
log: http://p.sipsolutions.net/d5926c43d531e3af.txt
trace: http://johannes.sipsolutions.net/files/xhci.trace.dat.xz
I plugged in the device, waited a bit, tried to run a camera application
(didn't work) and then ran lsusb -t and lsusb -v.

Mathias, would you have time to give this a quick look ?
