[Nut-upsuser] freenas USB connection error

Hi all,

I'm a new user trying to get a Proline UPS I1000 UPS to work with freenas
9.3
over USB. When running upsdrvctl I get a permission denied error.

Required debug info:

    OS name and version,

# uname -a
FreeBSD freenas.local 9.3-RELEASE-p5 FreeBSD 9.3-RELEASE-p5 #2
r275790+f84e770: Tue Dec 23 23:35:33 PST 2014    
root at
build3.ixsystems.com:/tank/home/jkh/build/93/FN/objs/os-base/amd64/fusion/jkh/93/FN/FreeBSD/src/sys/FREENAS.amd64
 amd64

    exact NUT version,

Network UPS Tools - UPS driver controller 2.7.2

    NUT installation method: from source tarball, package or Subversion,

package

    exact device name and related information (manufacturing date, web
pointers, ?),

Proline UPS I1000 UPS, purchased mid 2014. rebranded something, not been able
to discover what. http://www.pinnacle.co.za/#!/product/1685

    complete problem description, with any relevant traces, like system log
excerpts, and driver debug output. You can obtain the latter using the
following command, as root and after having stopped NUT:

It appears that there is a problem with reading/writing to the usb for this
ups.

NOTE: I tried the UPS with my laptop running mint linux and nut 2.7.1 and
there were no problems with the USB interface.


Any ideas?

Here's the strange part: the driver successfully queried the UPS once, and
got a valid string back.

However, this part indicates that there is a disconnect between the NUT driver
(which printed "Permissions problem" due to an EPERM return code
somewhere), and the kernel driver, which returned EIO.

Sadly, all nonzero error codes get mapped to EIO here:

   http://fxr.watson.org/fxr/source/dev/usb/usb_generic.c?v=FREEBSD92;im=10#L911

If we look further into the kernel driver, it appears that there are some
debugging messages:

   http://fxr.watson.org/fxr/source/dev/usb/usb_request.c?v=FREEBSD92;im=10#L393

It is unclear as to whether this can be enabled with a sysctl (hw.usb.debug), or
if additional #defines are needed. For this, you might want to check with the
FreeNAS folks, or try the FreeBSD USB list.

This is a bit of wishful thinking, but NUT 2.7.2 also has a newer driver for
Megatec equipment: nutdrv_qx. While I don't recall any FreeBSD-specific
tweaks to it, trying it would probably be faster than recompiling the kernel,
and there is little to lose.
