OpenSUSE ehci module (usb) suddenly shuts down

Dimanche, octobre 12th, 2008

I have been experiencing one of the most annoying bugs on linux so far. Usually the only worse of not working is if something is working just slow. When I switched on the computer, the usb devices are stopped to work (every single time) after a while, then after about 3-5 minutes they have started to work again (!), only they were impossibly slow (FullSpeed, about 800k). As I had two usb harddisk attached, this has been unacceptable.

The cause of the problem was that I plugged an usb hub into an other one. However the primary hub was self powered (plugged) into electricity, the system got confused. The second hub, and this is important, was a keyboard with usb connectors. As a solution, I have plugged the keyboard into the computer instead of the hub.

I have recently purchased a motherboard with ATI digital sound and I have lot’s of trouble getting it run on OpenSUSE 11.0. I wanted to use it on skype, but the microphone was not working. After playing for a few HOURS, I have managed to get it run in the front mic, but the sound quality was very poor.

The solution was annoyingly simple. It has to be set up in YaST. I didn’t try YaST auto config, because I supposed that, the same script is run at installation. It can also interfere with VirtualBox. So if you don’t need it for all price, then just shut it down.
