I have an USB soundcard that causes trouble. It's the Creative Audigy 2
NX USB, and I know that this beast is a pain in the ass because Creative
doesn't really care to follow USB audio standards.
Anyway. I have a Gentoo box, kernel 2.6.7, a laptop with USB2 and
hotplugging is running. When booting the box alsa loads and the device
works. But then I unplug the USB cable of the Audigy and the trouble
begins. The first thing I get is that no keyboard, neither the laptops
own keyboard nor the plugged in Cherry USB keyboard, works anymore....
Interesting. Maybe that ALSA driver has some problems. Does the
other usb audio driver behave for you?
I've had a few reports of unplugs triggering some rude errors
that add up to IRQ lossage ... and at least one of them was
unquestionably when using an audio device. That was with OHCI,
and you're using UHCI.
