I am attempting to run the various USB example programs on the nRF52840-PDK USB, but my nRF usb device is not being recognized (in windows OR linux device tree). Is there anything I need to change on the dev board itself? I have tried running various examples, and I don't see why I would be having trouble with the USB HID devices.

Thank you!

You are connecting the nRF52840 PDK to your computer through the nRF USB connector and not the one USB connector that goes to the interface MCU?

Yes, I am connecting through the nRF USB. Thank you.

OK, so NRF Power Source(SW9) is is set to VDD and SW6 is set to Default. If I flash the USB HID Generic Example to the nRF52840 PDK, then a mouse (nRF52 USB HID generic Demo) is added under Devices and Printers in Windows 7 .

I've tried this all with no luck. The program flashes fine, but I've tried plugging it into multiple Windows 7 machines and always get the same error: Error Code 43, USB device not recognized.

Are you using one USB cable to flash the nRF52840 and then you re-connect it to the nRF USB connector? Or are you using two separate cables?

I have tried both methods with no success.
