Axeman Falcon Posted May 18, 2015 Report Share Posted May 18, 2015 Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed. AVR usb is recognized but FPGA gives me a device not recognized.I have uninstalled and reinstalled all software 3 times.I disable the enabled but that didn't work. I've tried uninstalling all usb drivers then installing only what the computer installs automatically then reinstalling software and driver but that didn't work.The user led is blinking, jumper is in correct position for FPGA USB. In device manager i'Ve checked show hidden devices under view. Two driver for papilio DUO FPGA serial converter A and B show up.I Have tried plugging directly into computer usb3 and usb2 and also tried usb hub for extra power but still no luck. I'm using windows 8.1 any suggestions on what i might try next. Quote Link to comment Share on other sites More sharing options...
