If you have a AVR ISP programmer (like USBtinyISP, or USBASP), you can program the microcontroller directly without using the USB port on the controller. I think this may help fix the issue. If you don’t want to do this yourself, you can send a support ticket to support.opensprinkler.com and send the controller back to us so we can take a look.
