I was redirected to this list as per the suggestion from the libusb mailing list.
It will be greatly appreciated that someone can suggest how to debug this problem?
With the new USB stack installed, do like this:
sysctl hw.usb.debug=15
Then run you program.
Then get all the lines with "ugen()" in the debug output.
sysctl hw.usb.debug=0
--HPS
Thanks for the fast reply.
