After a day of tinkering with my Arduino Nano, I think I have somehow damaged the USB connector and can no longer make it connect to my PC. When I plug it in there are no lights on the board, and my PC does not detect the device at all.
The Nano its self appears to still function, when it is powered via the 5v and GND pins it lights up and interfaces with my hardware as it should for the last sketch I had uploaded to it. It seems to just be the USB connector which are dead. I can't see any damage at all to the Nano and honestly have no idea what happened (I disconnected an external LED from pin13 and heard that familiar "USB device disconnected windows" sound, and haven't been able to get it going via USB since). My other Arduino is still connecting to the PC fine, so the PC is OK.
I am wondering if there is a way to upload a sketch to the board without using the USB connection? Something similar to burning a bootloader to it using another Arduino as ISP (which I have done before, and do have another Arduino which I can use for this purpose).
I'm hoping I haven't turned it into a teeny-tiny brick. Cheers in advance for any help!
