nRF52840 board is not detected via USB

[Kavya]

Hello, 

LED 5 blinks fastly and LED 1 blink slowly on nRF52840 and I cannot see the device via USB. I have previously flashed zephyr blinky example code few days back and it worked well. Later Today, I connected the board to PC to flash new code and device is not detected on PC via USB.

I have tried to enter bootloader mode and placed .bin as suggested in other threads. But did not work.

I have also check the USB cable and USB port. There is no issue here. 

Please help me in solving this issue.

Thanks

Hello,

Issue is resolved. I used a virtual machine to flash earlier and now I am trying to connect to host PC directly. As i did not turn off the USB on VM, nordic board is automatically connected to VM and not to host. Issue is resolved when USB on VM is turned off.
