obskyr:
While a CH340 Arduino clone is connected to the computer, trying to enter sleep mode causes the computer to start but never actually finish entering sleep mode, and eventually crash with the bluescreen "DRIVER_POWER_STATE_FAILURE"
The same thing happens here on Windows 7: when I want Windows to shut down it takes 10 minutes or so before I see a BSOD, and then the PC reboots (!). The only solution I could fnd is just disconnecting the USB connector...
