I have USB DVB-C TV Stick tuner and it has a problem with returning from windows stand by mode.
[english: This device is not working properly, because Windows can not load the correct driver for it. (Code 31)]
To reproduce error, the tuner must be in use (for example, running ProgDVD) when you're moving PC into stand by mode.
To fix problem I disable device in Device Manager and then enable it again.
My software configuration:
Windows 7 X64 Professional
USB DVB-C TV Stick driver ver. 22.214.171.124
