I just upgraded an Inspiron 7500 laptop from RedHat 9 to
Centos 4.3 and the external USB sound no longer works. It worked
fine under RedHat 9. Now my toddlers cannot watch their DVDs
so please help me :-).
The 2.6.9 CentOS 4.3 kernel starts up usb and goes into a loop
adding and removing the external audio box:

The speakers just click every few seconds and the device gets added and removed
by the kernel.
Doing some research, I found mention of problems with overcurrent detection
for some hardware, and I am definitely getting a message to that effect,
so I upgraded the kernel to the latest -- 2.6.20-rc2 -- to
see if the (new) ignore_oc flag would fix this. It changed the behavior but
didn't fix the problem. Looking at the light on the USB audio box it looks like
it is just enabling and disabling the peripheral at much higher speed. Here
is the appropriate part of the syslog:
