Re: Mouse and keyboard troubles with USB -> PS/2 adapter

Hi!

Svetoslav has been helping me a lot off-list, but touched by your 
attention, I guess I can bring it back on... :-)

I've upgraded to 2.4.22, Marcelo's tree, and patched with the latest 
bruby patch now, and I haven't seen this message since. (The patch 
didn't apply cleanly to the debian kernel-source, but nevermind).

I guess this fixed that problem.

The current status is (on the surface) that X starts OK on both screens, 
but only the main PS/2 keyboard works. There's no output from the 
devices in /dev/input/ except event1, which is the PS/2 keyboard. The 
primary mouse (on the PS/2 port) is dead, not even giving output to 
/dev/psaux (and haven't for a few different configurations...), and the 
secondary keyboard and mouse are also quite dead...

A new set of logs and config files (aka "More about my system than would 
be good for anybody's sanity) is to be found at 
http://dev.kjernsmo.net/tmp/multi-user-logs3/

Yup, the funny thing now is that my non-bruby 2.4.22 kernel detects both 
the mouse and keyboad on this device:
input: USB HID v1.00 Keyboard [Tangtop Generic USBPS2] on usb1:2.0
input: USB HID v1.00 Mouse [Tangtop Generic USBPS2] on usb1:2.1
whereas the bruby kernel only detects the keyboard. 

That is, in dmesg I see
keyboard.c Tangtop Generic USBPS2 vc:17-17
input: USB HID v1.00 Keyboard [Tangtop Generic USBPS2] on usb-00:04.2-2

(so, I'm now starting the second X-server with vt17, OK?)

One of the recent things I've done, following Svetoslav's advice, is to 
add
above hid usbcore
to modules.conf (or rather /etc/modutils/local, that's how I understand 
the Debian Way... :-) ).  I was for a while seriously confused, as 
KEYBDEV was not available in the kernel, but HID wanted it... :-)

Allthough the above looks like the keyboard it least should be loaded, 
there is little to be seen in 
http://dev.kjernsmo.net/tmp/multi-user-logs3/proc.bus.usb.devices
Mmmm, I much prefer the way it looks in /proc/bus/usb/devices of my 
currently running non-bruby kernel:
P:  Vendor=0d3d ProdID=0001 Rev= 0.01
S:  Manufacturer=Tangtop
S:  Product=Generic USBPS2
C:* #Ifs= 2 Cfg#= 1 Atr=a0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=01 Driver=hid
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=10ms
I:  If#= 1 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=01 Prot=02 Driver=hid
E:  Ad=82(I) Atr=03(Int.) MxPS=   5 Ivl=10ms

Currently, /dev/input/mouse0 is my USB mouse with the non-bruby-kernel. 

There are a couple of lines in the bruby-kernel dmesg that looks 
somewhat suspecious...:
usb-uhci.c: interrupt, status 2, frame# 658
hid-core.c: ctrl urb status -75 received
I can't see that in my non-bruby kernel dmesg (ok, since I'm talking so 
much about it, I've dumped that too on my website)... 

I think I'm getting close now... :-) Help for the final bit would be 
greatly appreciated!

Best,

Kjetil
