System log error messages

[WS Grave]

Hi, I'm getting every 15 minutes an alarm peep by my Alix-1D and a lot of these messages in the system log:
Aug 18 16:26:34 meteohub kernel: usb 2-4: usbfs: USBDEVFS_CONTROL failed cmd hidlog3 rqt 33 rq 9 len 8 ret -110

What do they mean (can't find it in the manual).

I'm using version 4.6m alix-1D and WMR200.

error message is ok, as ALIX throws some errors on USB HID conncetion. No reason to worry.

Alarm beep sounds strange to me. Does the unit do an automated reboot or what is happening exactly.
