    _______________________________________________________

Details:

Currently "usbdev_open" attempts to open a device before check that the USB
VID/PID combo match the required programmer.

This patch checks the USB VID/PID combo before attempting to open the device. 
This allows an error message to be generated for when the correct device has
been found on the bus but the user can't access it (for example due to
permissions).
