Hi. I recently purchased x2 18v15 to drive some motors. these motoers draw about 2 amps under load each. I have only been able to bech test a test motor i have, with initially everything ok. I acciedenlty shorted out the 1st motor controller and now it is completley dead, no leds or anything. The second 18v15 has a permanant red error led stsying on and i cannot figure out what is causing this. I have plugged it back in several times and windows does not recognize usb device. It will also not recoginsie it in pololu simple motor controller software. I spent a considerable amount of money and just havent had any sort of joy. Any help/advice would be much appreciated.
Thankyou
