As per topic as there are not driver for my tablet trust tb-4200 and pinnacle usb pctv hybrid pen for windows xp x64,I was wondering if the driver for vista x64 that are present could work.

yeah!!! depending the hardware.. for example I have an HP laserjet 1020 with XP X64 using Vista X64 driver and it works well.

Is this a personal experience or could you explain me why? Thanx by the way

This is a really good question from topic starter.

Just for my knowledge. All my hardware runs fine under X64 except the AKA0110 device. I don't know exacly what it is, but my system runs fine without it . the only thing I know is that there's in Vista a fix for it and for x64 not. It is a motherboard device, but the function of it is still unknown by me

I ment it has something to do with ACPI, but the sleep function in X64 works excellent.
