I have an arduino nano which connected to my ubuntu 10.10 perfectly work. But if my arduini nano 3.0 is externally powered, there is an error:
[39779.161295] usb 2-2.2: new full speed USB device using uhci_hcd and address 11 [39779.573023] usb 2-2.2: device not accepting address 11, error -71 [39779.574357] hub 2-2:1.0: unable to enumerate USB device on port 2
If i connect my arduino usb and after i power on externally, that's work??
What's the matter?
