RealTelstar, I have been running the v1.10 bios for a few days now and I have yet to come across any USB issues. My g700 mouse works fine wired or wireless as does the MS X4 keyboard, a few USB flash drives, an Xbox360 controller and my mobile phone. Once I come across any USB problems with any other devices I'll post here. I am running Xfast-USB on my Z68X4G3 and still tinkering with OC settings (at 4.7ghz @ 1.40v right now; 4.8ghz @ 1.425v is not quite stable for my i5-2500k yet without temps getting to almost 90c).

Ket, I see you summed up some issues with the gen3 boards for Asrock support: I have a Creative X-Fi Platinum PCI card in the bottom PCI slot on my board but I'm not running the official creative drivers for win7x64. Instead I used "PAX PCI XFI ALL OS Driver V4.60" and it seems to be running well without any installation issues. Perhaps you are right and it could be a driver issue causing conflicts?

I haven't had any other major compatibility issues with this board yet, although I was thinking about installing a Sata3 SSD like a Vertex3 but after having a look through the OCZ forums they seem awash with people having problems and BSODs. It seems to do with the latest sandforce controller not playing with the Z68. I guess I'll wait for a while and do some more research...
