[Nut-upsdev] libusb_get_string: invalid argument

Hi - I just installed NUT from source, using the usbhid-ups driver for
a tripplite UPS (i compiled with the appropriate flag for the USB
device).
NUT version is 2.7.3. I
UPS is AVR900U

System is archlinux - fully up to date, running on an ARM device.
Linux <Systemnameomitted > 3.1.10-35-ARCH #1 PREEMPT Fri Jan 23
19:14:18 MST 2015 armv5tel GNU/Linux

I can communicate with my UPS - no problems

But in my system log i constantly get: "usbhid-ups[27732]:
libusb_get_string: Invalid argument"


command to launch: /usr/local/ups/sbin/upsdrvctl start

-------------------------- ups.conf:

[tripplite]
        driver = usbhid-ups
        port = auto
        vendorid = 09ae
        maxreport   # This was added as per the manual, as a
workaround for some bug. It didnt have any effect here

--------------- upsd.conf is fully commented out right now

------------Driver debug log

Here is the driver debug log. If I just let it run, it pops up with
libusb_get_string_invalid argument over and over again, mixed in the
debug output. seems to be several issues reported in the log, but they
arent easily interpreted.

Does the libusb_get_string error occur only every 30 seconds or so?

The entries with hex numbers in the path aren't important - the driver tries
to dump them once at startup, then does not refer to them again.

I think this is from trying to retrieve the value corresponding to
"device.part" - which should also only be attempted once at startup.

Try the attached patch?

Also, I would be interested in the output of "lsusb -vvv -d 09ae:" for
your UPS.

Yes - thats correct. perhaps more like every 15 sec.
