Just built and installed nut 2.4.1 with a usb.conf that looks like
driver = usbhid-ups
port = auto
desc = "Tripp Lite SmartPro 2200RMXL2U"
The OS is Ubuntu 8.04.2 with kernel version 2.6.24.
When trying to start the driver I get
$ sudo ./upsdrvctl start
Network UPS Tools - UPS driver controller 2.4.1
Network UPS Tools - Generic HID driver 0.34 (2.4.1)
USB communication driver 0.31
Can't claim USB device [09ae:3012]: could not detach kernel driver from interface 0: Operation not permitted
Driver failed to start (exit status=1)
The UPS is detected when connected. From the output of dmesg
[689484.575866] hiddev96hidraw2: USB HID v1.10 Device [Tripp Lite TRIPP LITE SMART2200RMXL2U ] on usb-0000:00:03.0-2
lsusb also lists the UPS.
