Nut upsuser - Jan 2008 - USBDEVFS_CONTROL error ?

Does the following error message have a specific meaning:

usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 161 rq 1 len 2 ret
-75


I get two of these messages every time I run the following:

/lib/nut/usbhid-ups -u root -DDD -a trippy



The following is the output from the above command:

The UPS is sending us here more data than we expect. The size of reports
is calculated from the 'report descriptor' we retreive from the UPS.
Apparently, when asking for this data, it returns more data than we
expected and therefor this error will be shown.

Unless some vital information about the state of the UPS is missing, I
wouldn't worry too much about it. Most probably, it is a bug in the UPS
firmware (which is all too common) you can't fix yourself.

Best regards, Arjen
