RedBearLab nRF51822 shows fail.txt with "timeout inside"
After working for a few weeks, my nRF51822 stopped connecting to my computer. When I plug in the USB cable to the computer, the new drive appears, and then I hear a disconnecting sound after a minute or two and the drive gone. Afterwards, the drive continues to reconnect. I have tried different computers, and different cables, all to no avail. I have not been able to upload sketches and drop .hex files so please help.

Right click on your device, Choose a safe removal device.
This will no longer cause problems with re-reading the device. And there is a COM port, which can be burned normally.
對著你的裝置按右鍵, 選擇安全的移除裝置。
如此便不會再出現一直重新讀取裝置的問題。 並且有COM port、可以正常燒錄。
