Arnaud,

do you know the cause of these errors?
usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd newhidups rqt 128 rq 6 len
255 ret -110
usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd newhidups rqt 161 rq 1 len
8 ret -110

These messages "pollute" my messages-files; is this hardware/software?
A problem with the USB-interface of the MGE-UPS?
I'm running 2.0.3 with the fix for this bug and it's been running
flawlessly with the exception of all these messages.

Rgds,
N.
