Finally, after 2 days crashing my head with the board, I find out the issue (which is related to all 3 nrd52dk original boards I bought). I read from another thread that sometimes there are issue with the boot loader and PCs, so I decided to reboot the board holding the reset button. The boards appeared as bootloader into my USB devices, and I drag and drop the latest J-Link OB-SAM3U128-V2-NordicSemi 170724.bin and power-of-power-on the nrf52dk. Finally it appeared as JLINK and com3 port device!

These are two PCs with Windows 8 and without having ne ed USB device issues. The strange thing is not only the reboot issue, but also the fact that the PC does’not boot until the usb Device is removed...I suspect a sort of “cpu” direct access from usb/jtag device...tibia possibile?did you see something similar? One pc is lenovo z500 with i7 cpu, while the other is an HP with Intel cpu

PC details - operating system, etc ?

Do these PCs have similar problems with any other USB devices ?
