Trying to get a Tripp-Lite to work with nut--Ubuntu 10.10. I was getting the error message "unable to claim USB device", tried to unbind the drivers to that device, and had the following delightful experience. In short, continue to get the same problem, and the drivers bound themselves back.
Any suggestions? ----------- usb.conf has the following: [Tripp-Lite] driver = usbhid-ups port = auto vendorid = 09ae productid = 2009 -------------- below is my terminal exchange with the computer --------------- rory@ubuntunas:/etc/nut$ ls -l /sys/bus/usb/devices/6-2*/driver lrwxrwxrwx 1 root root 0 2011-02-13 17:11 /sys/bus/usb/devices/6-2:1.0/driver -> ../../../../../../bus/usb/drivers/usbhid lrwxrwxrwx 1 root root 0 2011-02-13 17:11 /sys/bus/usb/devices/6-2/driver -> ../../../../../bus/usb/drivers/usb rory@ubuntunas:/etc/nut$ sudo sh -c "echo '6-2:1.0' > /sys/bus/usb/drivers/usbhid/unbind" rory@ubuntunas:/etc/nut$ ls -l /sys/bus/usb/devices/6-2*/driver lrwxrwxrwx 1 root root 0 2011-02-13 17:11 /sys/bus/usb/devices/6-2/driver -> ../../../../../bus/usb/drivers/usb rory@ubuntunas:/etc/nut$ sudo sh -c "echo '6-2' > /sys/bus/usb/drivers/usb/unbind" rory@ubuntunas:/etc/nut$ ls -l /sys/bus/usb/devices/6-2*/driver ls: cannot access /sys/bus/usb/devices/6-2*/driver: No such file or directory rory@ubuntunas:/etc/nut$ sudo /lib/nut/usbhid-ups -DDDD -a Tripp-Lite -x exploreNetwork UPS Tools - Generic HID driver 0.34 (2.4.3) USB communication driver 0.31 0.000000 debug level is '4' 0.002409 upsdrv_initups... 0.313715 Checking device (1D6B/0001) (008/001) 0.313846 - VendorID: 1d6b 0.313873 - ProductID: 0001 0.313893 - Manufacturer: unknown 0.313912 - Product: unknown 0.313934 - Serial Number: unknown 0.313952 - Bus: 008 0.313973 Trying to match device 0.314024 Device does not match - skipping 0.314060 Checking device (1D6B/0001) (007/001) 0.314120 - VendorID: 1d6b 0.314141 - ProductID: 0001 0.314158 - Manufacturer: unknown 0.314176 - Product: unknown 0.314192 - Serial Number: unknown 0.314210 - Bus: 007 0.314226 Trying to match device 0.314248 Device does not match - skipping 0.314278 Checking device (09AE/2009) (006/002) 0.314342 - VendorID: 09ae 0.314363 - ProductID: 2009 0.314380 - Manufacturer: unknown 0.314397 - Product: unknown 0.314414 - Serial Number: unknown 0.314431 - Bus: 006 0.314473 Trying to match device 0.314570 Device matches 0.314602 failed to claim USB device: could not claim interface 0: Operation not permitted 0.314630 failed to detach kernel driver from USB device: could not detach kernel driver from interface 0: Operation not permitted 0.314655 failed to claim USB device: could not claim interface 0: Operation not permitted 0.314681 failed to detach kernel driver from USB device: could not detach kernel driver from interface 0: Operation not permitted 0.314710 failed to claim USB device: could not claim interface 0: Operation not permitted 0.314739 failed to detach kernel driver from USB device: could not detach kernel driver from interface 0: Operation not permitted 0.314765 failed to claim USB device: could not claim interface 0: Operation not permitted 0.314794 failed to detach kernel driver from USB device: could not detach kernel driver from interface 0: Operation not permitted 0.314816 Can't claim USB device [09ae:2009]: could not detach kernel driver from interface 0: Operation not permitted rory@ubuntunas:/etc/nut$ ls -l /sys/bus/usb/devices/6-2*/driver lrwxrwxrwx 1 root root 0 2011-02-13 17:16 /sys/bus/usb/devices/6-2:1.0/driver -> ../../../../../../bus/usb/drivers/usbhid lrwxrwxrwx 1 root root 0 2011-02-13 17:16 /sys/bus/usb/devices/6-2/driver -> ../../../../../bus/usb/drivers/usb
