Problem with usb in FreeBSD 4.8....help!!!

[jitendra pande]

Hi Toni,
 
Thanks a lot for the information.
 
My device is the one which supports control transfers only thus i understand that for a second device i need to use /dev/ugen1 and so on.
 
Does that mean, i need to explictly make a node /dev/ugen1 and /dev/ugen2 and so on for  every newly added USB device using MAKEDEV script. 
 
Please advise me , if there exist some better way of handling the situation. Is there some sort of modification that i can make to libusb to handle the situation.
 
Thanks and regards
Jitendra

Note that the port version of libusb (0.1.7_1) ignores device endpoints
(/dev/ugenX.Y), so it may be necessary to find and open them by yourself.

Also note that opening the control endpoint (/dev/ugen0) instead
will prevent libusb from finding the device, because FreeBSD allows
the control endpoint to be open only once:

usb_os_find_devices: couldn't open device /dev/ugen0: Device busy

Also note that on 5.x (or -CURRENT) there are other problems to
watch out for:
