USB optical mouse stops working when plugging pendrive


I have a Logitech usb optical mouse. It appears that when I plug an USB 2.0 pendrive the red light under the mouse turns off and it stops working. I have these messages in /var/log/messages:

Nov 24 09:12:42 Paradise usb 2-1: new low speed USB device using uhci_hcd and address 61
Nov 24 09:12:43 Paradise drivers/usb/input/hid-core.c: ctrl urb status -71 received
Nov 24 09:12:43 Paradise input: USB HID v1.10 Mouse [046d:c03e] on usb-0000:00:1d.1-1
Nov 24 09:12:43 Paradise usb 2-1: USB disconnect, address 61

These messages keep on appearing with the address gets increasing 61,62,63,64 etc until I unplug the pendrive.
Moreover the system slows down and I find this processes running with the state S<:

udev input
udev input
udev usb

When I unplug it the system is still slow (the mouse pointer doesn't move smoothly) and I get these processes:

30582 ?        S<     0:00 udev usb
30583 ?        S<     0:00 /sbin/udev_run_hotplugd usb
30585 ?        R<     0:00 /bin/sh /etc/hotplug/usb.agent

I have udev 0.71 (but it was happening also with '0.68') and kernel

This appears very often but not always. I'm sure it's not an hardware incompatibility issues because when I was running Slackware with the same hardware (mouse included) I didn't have this problem. Does anyone have a clue ? On the net I didn't find anything.

Really thanks to anyone can help me,

Re: USB optical mouse stops working when plugging pendrive

sounds like an IRQ conflict. See if disabling plug and play in the bios solves it. Arch's kernel provides this already.

Re: USB optical mouse stops working when plugging pendrive

Getting rid of hotplug should also help.
