I'm attempting to get a HP R1500 G2 UPS working with Solaris 10
connected via USB.
Thanks to Arnaud's patch to drivers/tripplite-hid.c found at
http://lists.alioth.debian.org/pipermail/nut-upsuser/2010-February/005887.html
things mostly work.
upsc ups01 shows a couple of things that don't look quite right.
[....]
battery.temperature: -234.1
[....]
ups.alarm: No battery installed!
But the real problem I'm having right now is it does not want to turn
off the UPS.
--------< ups.conf >--------
[ups01]
driver = usbhid-ups
port = auto
desc = "HP R1500 G2"
offdelay = 120
----------------------------
Here is the last part of the log from
"/opt/mt/nut-svn/libexec/usbhid-ups -DDDDD -a ups01 -k"
.....
opening /dev/usb/3f0.1fe0/0/cntrl0
opening ep0 failed, -1

usb_error(): error=22

0.018193 Failed to open device, skipping. (Invalid argument)
0.018350 No appropriate HID device found
0.018511 No matching HID UPS found
.....
And running it under truus I see thih line
838: open("/dev/usb/3f0.1fe0/0/cntrl0", O_RDWR) Err#16 EBUSY
So it looks like maybe it was opened in exclusive mode.
Any thoughts?

(Technically, the interfaces are opened exclusively, but most UPSes have only one HID interface, and that's what we use.) The intent for the "-k" flag is that the system is ready for the power to be cut, so the first thing I'd check is whether there is another usbhid-ups driver still running. If not, you might need to use "lsof" or something similar to see what else might have claimed the device/interface in the mean time. -- - Charles Lepple
