[SOLVED] USB sound broblem.

Greetings everyone. Kinda sucks making my first post on new boards this way.

Can't say I am very experienced linux-wise, but until now I successfully overcame all problems I've encountered. On this one I can't even think where to start, because all this kernel stuff is kinda complicated to me yet.

After initial install all hardware were detected and working well. During days of polishing system I lost track of changes and can't really say what triggered my USB sound card disappearance. At first I was blaming ALSA, but then I checked kernel.log:

As you can see: there is no usb 6-1 "After". Let ALSA messing alone (because it seems unrelated) so far I tried:
- different USB ports
- reinstalling kernel

Any tips or solutions are welcome.

Re: [SOLVED] USB sound broblem.

After reinstalling udev, I atleast started to getting following things:

Oct 15 18:22:36 localhost kernel: usb 7-1: new full speed USB device using uhci_hcd and address 2
Oct 15 18:22:36 localhost kernel: usb 7-1: device descriptor read/64, error -71
Oct 15 18:22:36 localhost kernel: usb 7-1: new full speed USB device using uhci_hcd and address 3
Oct 15 18:22:36 localhost kernel: usb 7-1: device descriptor read/64, error -71
Oct 15 18:22:36 localhost kernel: usb 7-1: new full speed USB device using uhci_hcd and address 4
Oct 15 18:22:36 localhost kernel: usb 7-1: device descriptor read/64, error -71
Oct 15 18:22:36 localhost kernel: usb 7-1: new full speed USB device using uhci_hcd and address 5
Oct 15 18:22:36 localhost kernel: usb 7-1: device descriptor read/64, error -71

I tried echo -1 >/sys/module/usbcore/parameters/autosuspend as somewhere suggested, but didn't help a bit.
There is also solution to disable USB 2.0 via modprobe -r ehci_hcd, but I cannot allow that because through this device I stream much bigger bandwidth, than USB1.0/1.1 can handle.

EDIT:
- tried to remove and modify /etc/modprobe.d/usb-load-ehci-first.conf to ohci load first
- tried to add "irqpoll" as kernel option
- echo Y > /sys/module/usbcore/parameters/old_scheme_first
No luck.

EDIT2:
Alright people. The device is gone for good. Other computers cannot see it as well, neither Windows 7 on media center or Ubuntu on laptop. Dunno if Arch fried it somehow ^_^

Re: [SOLVED] USB sound broblem.

Maybe too obvious, but could it be broken  connectors/cables?

Re: [SOLVED] USB sound broblem.

Is it still under warranty? If so, let a technician have a look at it.
