You did spot my mention of the MANY HOURS I spent reading and trying to downgrade BIOS? ;-) My son and I concluded that the only remaining POSSIBILITY to downgrade would be to deliberately flash a corrupt BIOS to then allow the Recovery Flash to put a new one on and then use an older version. I am not the kind of person to give up but believe me I tried everything I could to downgrade... If you can manage it then you ARE a better man than me!!!!
Thanks for the Plist.. yes thats the one I wanted...
There is also another USB EHCI type flag if memory serves. Might work? I'll try myself shortly... assuming I get the resolution etc working with the Plist!!
For the USB, tried each one individually, and all together...still no work...
USB Bus Fix
EHCI Acquire Fix
UHCI Reset Fix
USB Legacy Off
Perplexing, but we are living in an imperfect world...
