While running a descriptor dump (code attached) on my USB speakers with
the hiddev ioctl()s in 2.4.5-ac7, I hit the following oops using JE's
UHCI. Repeatable on this HCD, not tried on OHCI or GA's UHCI.
>>EIP; 00000000 Before first symbol
Trace; c885d423 <[hid]hiddev_ioctl+293/920>

Trace; c014e8b7 <sys_ioctl+237/2c0>
Trace; c0107437 <system_call+33/38>
On a related note, what is the concensus about whether speaker HID
should be directed to input or to raw HID events? I am currently
thinking input events, because that would allow common work with
equivalent buttons on a keyboard.
