I think I'll try to attempt to redo your libusb hack by copying it from the older gnuradio recipes and attempt to use the original USRP USB driver if the problem ends up being too major ... unless you want to do that as a favor to me and push the recipe into the openembedded tree !!! pretty please :)

Al,
Which USB port are you using to connect the USRP1? What kernel version?
Can you run dmesg and see if there are any usb related messages at the end?
