I was working with my Arduino Nano V3.0 (Funduino not Gravitech... :0) and everything was fine. I changed a few wires on my breadboard and then the next time I plugged in the PC's USB cable into the Nano, the Nano wasn't detected. No sound from Windows XP fo USB device plug in notification.
The board still seems to function in a weird way though. I noticed that with USB power, the blue power LED on the nano is lit but much dimmer than normal. And also, the TX and RX LEDs are flashing simultaneously and at a dim level also. Reset doesn't fix the problem.
I tried powering the Nano with a 9volt battery only and the power LED lights up at full brightness, the TX and RX LEDs are inactive, but my last loaded sketch doesn't work.
I tried searching the internet for answers but there's no clear solution since I can't figure out if I did something wrong or if the board simply failed. Any replies to this is much appreciated.
