USB devices not working once plugged out

Hi,

Once I plug out any USB device, that was working before, and plug it in subsequently it stops working. For example, I am able to use a mouse, and than I plug it out and plug it in, and now it stops working. Even its IR sensor is powered off.

When I look into dmesg output the following messages appear:

[  435.000070] usb 7-2: USB disconnect, device number 2
[  437.146705] uhci_hcd 0000:00:1d.1: PCI INT B disabled

The kernel version as reported by uname -r command is 3.0-ARCH.

Moreover, the problem seems to disappear when I use LTS kernel.

Can somebody please suggest a fix to the above problem.
