Which kernel version?
This is a "stock" 3.2.0-4-686-pae but was the same on 2.6.18 from debian 6
squeeze.
It happens several times a day that I get a message about

Error -110 is indeed a timeout, but it is not directly coupled to pollinterval.
NUT 2.7.1 increases most of the USB timeouts from 4000 to 5000 ms, but
if this error is after the driver initialization has completed, then the
increased timeout is not as likely to help.

This problem is between your USB hardware and your kernel. (The previous error
may be related.)
Without knowing your USB host controller, I'd say it might be a USB

cable or port issue. Try another USB cable (preferably shorter), and
also try a different port. If that doesn't fix it, you probably want to
OK, you are right, I'll try that.
check with the linux-usb list to see if there is a known issue with your
kernel version.
Understood.
There really isn't much that NUT can do there, besides recover
gracefully. The reconnection logic should be in usbhid-ups.
