Help, the Windows update on the 8th of June knackered my touchscreen and USB functionality (including the xHCI driver) on my brand new laptop.
Rolling back does not fix it and although I've managed to get the mouse working again it has very limited functionality with no scroll wheel and this is one of the newer Microsoft mice so its not out of support.
Everything was working correctly before the update and came with 8.1 installed so its not like I was the victim of a problematic upgrade, my desktop machine has experienced no such problems so I'm thinking this is to do with the components of the laptop motherboard somewhere.
My machine is a Dell 7737 17" with core i5 4210, I'm not willing to let the Dell idiots into my machine as they always say upgrade the BIOS (mine is at the latest version) or do a factory reinstall (yeah right that would fix it until the next update ran and broke it again!).
I'm pretty savvy with fixing software and update issues but this one seems very hard to nail down, device manager says that I have an Unknown Touchscreen (well it knew what it was before the update on the 8th!) and the transciever for my mouse is not functioning.
