USB -> Unknown Device (Nano V3.0 + DFRobot I/O Expansion
pchalermwat 2011-04-28 08:39:14 7185 Views4 Replies Hello Please Help!!,
I've got my new Arduino Nano V3.0 and it works fine alone. My computer recognizes it when connect to USB port. But when I snap the Nano to DFRobot I/O Expansion (Roboduino Nano Expansion) 2009 the computer reports "Unknown Device" when trying to connect it via USB cable. I appreciate any suggestions/work around.
Thanks,

pchalermwat 2011-05-01 02:29:40 Nothing on the I/O board. I also try various combination of jumpers on the board but wouldn't help. I'll try another USB cable as per your suggestion. Thanks for your feedback. pchalermwat
pchalermwat 2011-04-30 01:15:25 Do you have anything that attached on your IO board?
And, one good tip is to try another USB cable. We found the cable do influence something sometime. R2D2C3PO
