changing OS from 32 bit to 64 bit.

I had a doubt that you will not hide microsoft drivers. So I made it bold. Still you ignored/overlooked it.

Is it any of these? https://www.nuvoton.com/NuvotonMOSS/...a-0d33583c2797

Search for any possible driver update for it. If no update is found there, better you dont use it.

And, Disable USB Selective Suspend too.
USB Selective Suspend - Turn On or Off

Nice. Let us know for any other issue, when all the suggestions are done. :)

the multimedia controller info. is 102F + 01BA
and the unknown device is ACPI\ TOS6205

It is Bluetooth. ACPI\TOS6205 drivers

You may get it from http://aps2.toshiba-tro.de/bluetooth...wnload-toshiba

But if Bluetooth is not a must for you, you may let it remain as it is.
