i am trying to use ndiswrapper on the backtrack 3 final usb with a pci netgear wg311v3 wireless card, and i cannot understand why it isnt working, here is what i get.

bt ~ # ndiswrapper
install/manage Windows drivers for ndiswrapper

usage:
ndiswrapper OPTION

-i inffile install driver described by 'inffile'
-a devid driver use installed 'driver' for 'devid' (dangerous)
-r driver remove 'driver'
-l list installed drivers
-m write configuration for modprobe
-ma write module alias configuration for all devices
-mi write module install configuration for all devices
-v report version information

where 'devid' is either PCIID or USBID of the form XXXX:XXXX,
as reported by 'lspci -n' or 'lsusb' for the card

bt ~ # ndiswrapper -i /root/folder1/wg311v3.inf
installing wg311v3 ...
couldn't open /root/folder1/wg311v3.inf: No such file or directory at /usr/sbin/ndiswrapper line 181.

bt ~ #

i went to line 181 and it didnt tell me anything but the command line used to display the error given above

please, i would appreciate any help that can be given.
