Dmesg error - mouse does not work after suspend

[fdservices]

This appears to be a known kernel problem, from googling, but I cannot find a solution. Can anyone point me in the right direction?

Dmesg shows:

[drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking

which may or may not be related to the problem that the usb mouse stops working after a suspend on my hp pavillion dm1 laptop.

Thanks

It looks as if the two incidents are not connected.

If I unplug the USB mouse after the resume, and plug it back in it is not recognised.

BUT if I plug it into a different port it is.

Now, how do I do that from the command line?

just try to run lsusb after resume...

It is quite interesting actually, lsusb shows the logitech usb device before suspend, but not after.

Re-plugging the usb key still does not show it up.

Plugging it into a different usb port and it shows up until the next suspend.

I only have three usb ports so after three suspends I have run out.

All the usb ports are set to persist==1

Thanks for the response
