Bug#314954: [Linux-usb-users] Re: logitech usb mouse "dies"
To get more information, turn on USB verbose debugging (CONFIG_USB_DEBUG)
in the kernel configuration and rebuild the USB drivers. Post the kernel
or dmesg log showing what happens when the connection is lost.
I've used the debian source for that. They currently don't patch
anything usb-related. I've set CONFIG_USB_DEBUG=y and changed the
processor family to Pentium M. These are the only differences to the
distributed debian kernels.
Unfortunatly, when the connection is lost, there is no message in dmesg.
And there's also no message when the connection is reactivated. (By chvt
1 && sleep 1 && chvt 7)
when I unplug and replug the mouse, the following happens:

Is there some usb sniffer for linux around? Maybe that would shed some
more light on this issue.
