Howdy nut-users :)
Got a problem with nut detecting my UPS.
Here's my scenario.
Base platform is a HP ML350 G6.
UPS is an APC Smart-UPS 1000.
Base OS is VMware ESXi 5.0 with all current patches.
I've created a virtual machine using the VMWare supplied VMA.
USB passthrough is configured to pass the UPS through to the VMA.
So I essentially have a SLES 11 (x86_64) server with a USB connected APC Smart-UPS 1000.
I've tested nut installed from package and from source (2.6.5).
Here's the diagnostic detail:

So we can clearly see the ups on the USB bus
/usr/local/ups/etc/ups.conf contains
[apc1000]
driver = usbhid-ups
port = auto
vendorid = 051d
desc = "Local APC SmartUPS 1000"
joavma01:/usr/local/ups/bin # ./usbhid-ups -DDDDD -a apc1000
Network UPS Tools - Generic HID driver 0.37 (2.6.5)
USB communication driver 0.31

1.042272 i=0, extra[i]=09, extra[i+1]=21
1.042278 HID descriptor, method 2: (9 bytes) => 09 21 00 01 21 01 22 03 02
1.042281 HID descriptor length 515

1.044252 Checking device (0E0F/0002) (002/003)
libusb couldn't open USB device /dev/bus/usb/002/003: Permission denied.

1.044481 Failed to open device, skipping. (Permission denied)
1.044487 No appropriate HID device found
1.044493 No matching HID UPS found
So ignoring all device except (002/002) since the ups user doesn't have access to them the problem appears to be:
1.044215 Unable to get Report descriptor: Broken pipe
Any ideas?
