Friend's got a new Tiny laptop (yes I know!) Tried to use 4 usb ports - nothing doing - on device manager I can't see usb controller or anything mentioning usb. Is it possible they're not connected on motherboard? Or is there a driver we need to download from somewhere in cyberspace? We have utility cd that mentions usb2 but can't work out how to install it from there. Laptop's just come back from factory once because, quote 'bios wasn't flashed correctly' thanks!
It all depends on the motherboard make, model and the type of BIOS so there isn't any specific advice I can give. You need to look at each page and look for something to do with USB. You don't need to worry too much about legacy USB as that is just for USB keyboard or mouse at startup (mine is set to AUTO). On one of my PCs with an AMI Bios, USB is listed on the ADVANCED page and has the following settings:
USB Function [Enabled]
USB 2.0 Controller [Enabled]
USB 2.0 Controller Mode [Enabled]
Your BIOS could have these settings or different ones. Just don't change anything that you don't understand and if you get into a mess just use the EXIT WITHOUT SAVING option and it will all revert back.
