+.SS "Repetitive timeout and staleness"
+
+Some models tends to be unresponsive with the default polling frequency.
+The result is that your system log will have lots of messages like:
+.nf
+ usb 2-1: control timeout on ep0in
+ usb 2-1: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 128 rq 6 len
256
+ ret -110
+.fi
+
+In this case, simply modify the general parameter "pollinterval" to a higher
+value (like 10 for 10 seconds). This should solve the issue.
+
Should we make this the default for this driver? For instance, by adding
poll_interval = 10;
in upsdrv_makevartable? It would still allow people to override this
(driver specific) default value, but might be a safer default than the
present default that is set in main.c and main-hal.c.
Best regards, Arjen
