Description Raphael RIGNIER 2006-02-02 08:39:42 UTC 
Most recent kernel where this bug did not occur: 2.6.12?
Distribution: Debian SID
Hardware Environment: USB only micro touwer PC (HP Du520) Intel P4 based machine.

Problem Description:
Hello!

My PS2 mouse and Keyboard are plugged into a composite USB to PS2 Adator.
When the kernel loads the usbhid driver, those input devices don't work anymore...

Here is en extract of dmesg output :
------------------------------------------------------
usb 2-1: new low speed USB device using uhci_hcd and address 2
usbcore: registered new driver hiddev
input: Composite USB PS2 Converter USB to PS2 Adaptor  v1.09 as /class/input/input0
input: USB HID v1.10 Keyboard [Composite USB PS2 Converter USB to PS2 Adaptor 
v1.09] on usb-0
000:00:1d.1-1
input: Composite USB PS2 Converter USB to PS2 Adaptor  v1.09 as /class/input/input1
input: USB HID v1.10 Mouse [Composite USB PS2 Converter USB to PS2 Adaptor 
v1.09] on usb-0000
:00:1d.1-1
usbcore: registered new driver usbhid
drivers/usb/input/hid-core.c: v2.6:USB HID core driver
--------------------------------------------------------- 

Steps to reproduce:
Plug a compsite USB to ps2 adaptor in any usb port, plug PS2 mouse and Keyboard
in it, and boot  the PC....

I thought it was udev's fault, but same config with 2.6.12 kernel works just fine!

Remove clear-halt from HID core

This attachment is a patch that has already been accepted in the 2.6.16
development kernel.  There's a good chance it will fix your problem.
