Hi Joe, It feels like this error comes from libusb. Moreover, it feels like a deployment issue, try to install libusb 0.1 from sources. If it doesn't work, try to backtrack a few libusb minor version and try again. Whatever, it is maybe a good to report your problem to libusb mailing list. If you know a bit of C language, you could try to write a little program que calls usb_bulk_read, just to see if the system can resolv the symbol...
