[Bug 915985] [NEW] usbhid-ups regression (APC BE525-RS)

[Dmitry Andreychuk]

Public bug reported:

Ubuntu 11.10
nut 2.6.1-2ubuntu2
UPS model: APC Back-UPS ES 525 (BE525-RS)
driver: usbhid-ups

I get the following error approximately every 30 seconds:
usb 4-2: usbfs: USBDEVFS_CONTROL failed cmd usbhid-ups rqt 161 rq 1 len 2 ret -75
The simalar error is described in the driver's known issues but increasing pollinterval doesn't help - the interval between error messages just increases accordingly.
I also noticed that battery.charge returned by upsc doesn't change when the UPS is actually discharging. I called upsc, unplugged UPS and called upsc again after a while: ups.status, battery.runtime and input.voltage reasonably changed but battery.charge stayed at 100%. So maybe the retreiving of this variable is working incorrectly.
Part of my ups.conf:
[be525]
  driver = usbhid-ups
  port = auto
  pollinterval = 60

Output for "sudo /lib/nut/usbhid-ups -u nut -a be525 -DDDD" is attached.

I've tested a few other versions and got this:
2.4.3-1ubuntu3.1 - ok
2.6.0-1ubuntu3 - ok
2.6.1-2ubuntu2 - error
2.6.2-1ubuntu1 - error
2.6.3 (upstream) - error. Actually I didn't manage to run daemon that I built from source, so I ran just the driver and it reported the same error.

Looks like this problem appeared in v2.6.1.
