I contacted Digi about this issue and the tech rep indicated that he had no record of the device number previously reported by me (0x0288). I was provided with a file of Digi devices as far as he was aware. Shall I send this file to linux-usb@xxxxxxxxxxxxxxx or a particular address? >From this file I performed the 'echo' suggested by Greg earlier with a device number that was in the file as follows: %Ep4rDeviceName% = Edgeport.Install, USB\VID_1608&PID_0202 With 0x0202 as the device, my con was filled with messages when I plugged the Edgeport/4r in. Then the system froze. Let me know what other diagnostics you'd like me to perform.
