Subject: 2.6.33: Intel DP55KG - USB still not fixed: USBDEVFS_CONTROL failed
 cmd usbhid-ups rqt 161 rq 1 len 4 ret -110

Hi,

Feb 28 19:39:10 p34 kernel: [274199.684428] usb 2-1.7: usbfs: USBDEVFS_CONTROL
failed cmd usbhid-ups rqt 161 rq 1 len 4 ret -110

I know the DP55KG has USB problems (still, apparently) but was curious 
what the (above) error means?

In addition, this occurs when the CPU is maxed out, this still occurs
(many interrupts/from a backup etc), someone at Intel needs to run
nut with a UPS and then run some heavy CPU-bound processes and they will
see the same problem.
