I'm running Win 7 x64, and working with a LOT of individual Arduinos and Arduino variants. Everything was going swimmingly, until I high COM255 and wrapped around to COM3 or so. After that, my computer detected the FTDI chip just fine but failed to assign a COM port to it. When I tried hitting update driver on the USB Serial Port, it timed out. I tried rebooting the computer, no dice. I tried uninstalling and re-installing the driver, which did not change anything. I removed all of the phantom devices, no change. I updated to the latest driver, no change.
Any thoughts on what I should do?
