Hi,
I am facing the same issue.
My main work is on windows and there are lot of tools that are required to be connected to USB. None of the drivers are now working.
Just need to know, this system is now totally unusable or is there any update or so that may happen in near future to handle drivers issue.
Same like, applications are emulated, can't the drivers be?
Else it is going to be a total waste of money for me spent on both MacBook Pro and Parallels
