Unknown USB Device (Device Descriptor Request Failed) with nrf usb port after sniffer firmware

[[email protected]]

I am using nrf52840 pdk for sniffing zigbee network. After flashing firmware from this link on board . After connecting  nrf usb port to  pc , windows giving error "Unknown USB Device (Device Descriptor Request Failed)"

The nRF52840 Preview DK is no longer supported or recommended to use, since it is based on preview silicon with many issues in general (due to issues in hardware and incomplete test program). Please order a new nRF52840-DK.

Best regards,
