Hi can anyone ps help me? I have just built a pc and i cannot get any of my USB's to work from any of the hubs i have. All usb's are working at back of case but on top of case wont turn on, nor will the ones on my Dell monitor which ive used for last 5yrs on XP. I am using Win 7 and have one of those new Asus M4A89GTD-pro-USB3 mobo's. I have also double checked that the USB leads are on correct plugs on mobo. I have also tried enabling plug and play in bios to no effect. Ps can you help as its a nuisance connecting at back of pc all the time?
