Problems communicating with Arduino Uno

Help & Support Robot Parts

Hi All,

Received my Arduino Uno today after having ordered it Friday. Talk about fast delivery!

I hooked it up and tried to install the driver, but I’m not having any luck. I’ve got the Arduino IDE (release 0022). Windows identifies the board as an ATmega8U2 DFU under “Other Devices”. I don’t get any ports mapped to the board either.

Following the Arduino instructions (arduino.cc/en/Guide/Windows) I tried to install the drivers, but nothing gets recognized. Checking the Drivers directory under the Arduino software, I do see the Arduino UNO.inf (as well as an Arduino MEGA 2560.inf) but nothing gets recognized as the correct driver.

Any suggestions? BTW, I’m running Windows 7 on an HP laptop.

Thanks,

Fred

Windows does detect the board. The Device Manager detects ATmega8U2 DFU under “Other devices” but does not show any COM ports at all. Device Manager does not even show a “Ports” heading to list the COM ports under. The Arduino IDE has disabled the Serial Port menu selection under Tools - apparently because it doesn’t find any COM ports.

Got my new board from Robotshop already - only about 24 hours later.

Plugged it in and it works like it should. The new board says it is an Arduino Uno versus the old (defective) board saying it was an ATmega8U2 DFU.

Drivers installed and example code tested. Works like a charm. Old board is on it’s way back.

Thanks Robotshop! Overall I must say the service was excellent, both from Technical and Customer Service Support.
