Hi everybody on this list.
I have a strange problem with:
a USB Logitech optical wheel mouse
+
a Sony VAIO Picturebook C1VE laptop
+
any recent linux kernel (currently 2.4.16...)
The problem is that the mouse is sometimes not recognized.
This can happen on the laptop boot (with the mouse attached),
or later when plugging it. It happens about 10% of the time.
I can reliably reproduce this using this in a script:
while /bin/true; do
rmmod hid
rmmod mousedev
rmmod input
rmmod usb-uhci
sleep 2
modprobe usb-uhci
sleep 5
done
When it fails, I have those messages in kernel logs:
...
usb.c: registered new driver hid
usb-uhci.c: interrupt, status 3, frame #1181
usb.c: error getting string descriptor 0 (error=-84)
usb-uhci.c: interrupt, status 2, frame #1186
usb-uhci.c: interrupt, status 2, frame #1190
and so on...
...
The strange thing is:
1. using the same mouse on several other boxes (including
laptops and workstations) doesn't exhibit the bug.
2. using another Logitech optical wheel mouse (same as mine,
but having firmware 3.20 instead of 3.10) on my laptop
doesn't exhibit the bug either...
So I'm pretty puzzled, does anybody have an idea on what is
happenning or something ?
Thanks.
As a side note, if I do in my script, after the "modprobe usb-uhci"
, a modprobe of input, mousedev and hid after a few loops I get a
kernel oops in usb.c:usb_find_interface_driver. This is also
reproductible but I think it's not related to my particular
hardware.
Stelian.
