Fails to remove device / doesn't detect power-on

[KevinGelking]

The script detects a valid GPU, tries to dump the vBIOS, sees the vBIOS is too small and then tries to remove the device and suspends the system, waiting for the power button to be pressed.
However, it fails to remove the device with an error and when the power button is pressed and the system powers on, the script doesn't continue execution.
