Comment 14 for bug 518234

No, I use a quite old Microsoft IntellyEye USB mouse.

If disconnecting mouse/tablet can cause this, then maybe I'm affected as well. I'm regularly getting messages in system log about disabled USB ports/hub (mainboard internal stuff) due to EMI. Depending on where my mouse is plugged in, my keyboard gets reset as well. I noticed it as the EL-backlight gets turned on every time it happens, which is quite annoying due to the inverter's high frequency noise. It could be either my mouse going bad or the mainboard's usb hardware.

well, I did a few tests. It seems that at least 2 of the mainboards onboard usb ports have this problem, and my mouse happens to be in one of them.

Tomorrow I'll install 0.48 on my laptop and see how it works there.
