I am not subscribed to the list. Please CC replies to me. Thanks. I am using a Logitech MX700 mouse, attached to the onboard USB controller of a VIA motherboard. Apparently at random, the mouse will stop sending events, or the USB controller stops receiving them.
This only started when I upgraded from kernel 2.6.5 to 2.6.7. I have another system running kernel 2.6.7 on a different computer using a Logitech MX900 mouse with a OPTi USB controller and it has no problems, so I suspect that the VIA controller driver is the problem. I can make the mouse start working again by doing cat /sys/bus/usb/devices/2-2/product. Now I'll attach all the messy details that REPORTING-BUGS says to include. :-) Thanks for your time. -- Zan Lynx <[EMAIL PROTECTED]>
