Hi attila, I tried to get the board running again on a different PC with Windows 10 Pro but I still have the same problem. I also tried a different power supply. I cut the trace between Jumper 1200, powered the board and connected it to the PC and this is what I get from the device manager: Hardware IDs: USB\DEVICE_DESCRIPTOR_FAILURE Device Instance Path: USB\VID_0000&PID_0002\5&39acf2ce&0&1 I then started the reprogramming tool but no device was listed there.

Hi attila, I tried the procedure, but unfortunately the reprogramming tool does not show any devices in the list. I excuted steps 1 to 4, started the reprogramming tool, disconnected the board, clicked next and reconnected the board, but no device is listed. Are there any other possibilities to solve this problem?

Hi Attila, thank you very much for your reply. I tried different usb cables and all USB ports on my laptop but this didn't solve the problem. My board ist Rev H, should I still try to reprogram the device? I didn't try it yet.

Hi, I bought an Electronics Explorer Board and it worked just fine until recently. Now when i plug in the board to my laptop it is not detected by the pc or waveforms anymore. When i go to the device manager, it says "Unknown Device" and when i look for the Hardware ID it say "USB\UNKNOWN" The yellow LED for USB and the red LED for power are on. Could someone please help me with this problem? Thank you very much in advance.
