Description Stuart Hayes 2005-01-25 15:27:42 EST
Description of problem:

We have a Dell Chicony USB keyboard (model KU-9985) which fails to 
work when plugged in.  There are ugly messages in /var/log/messages, 
and "lsusb" will hang.

It turns out that this keyboard says that it has both a keyboard and 
a mouse, though there really is no mouse at all (no PS/2 port, no 
mouse).  When Linux issues a "get_report" for the mouse reports, the 
keyboard stalls, and things go downhill.

This keyboard works fine if we add it to the blacklist with 
the "NOGET" quirk.

Version-Release number of selected component (if applicable):

How reproducible:
Very easy.

Steps to Reproduce:
1. Boot up system.
2. Plug in KU-9985 Chicony usb hub keyboard.
Actual results:
Keyboard doesn't work, there are ugly messages, and "lsusb" will hang.

Expected results:
Keyboard should work, lsusb should work normally.

Additional info:
I will attach the patch.

Vojtech accepted this but did not notify me. I'm going to post
this to review in a few hours. U2?
Comment 3 Stuart Hayes 2005-03-16 10:07:57 EST
U2 is fine.  Thanks!

Modified in 2.6.9-11.30.EL (actually before that, but I have verified
it on this version).
