Re: USB keyboard and mouse not working
Depending on the device, some need to draw power from the USB port. I have
a Razer Diamondback gaming mouse that will only work from a powered USB
port. Most hubs do not provide power. You can buy powered USB hubs. This
could be worth a try if they're not too expensive. Bear in mind you'll have
to find another mains socket for it though.
USB extension cords might be a more practical (and cheaper) alternative.
Most ordinary mice do not draw as much power as mine, by the way. My old
Intellimouse Explorer worked fine from one of the USB ports built into the
keyboard. The keyboard should be plugged directly into the PC though,
especially if you have a BIOS that's able to detect it.
Another good reason to have your most important devices plugged directly
into the PC is that hubs introduce delay. Your keyboard and mouse are vital
to the operation of your PC and should be among the first things it finds.
How many USB ports (not counting the hub) does your PC have? There may be
some spare headers on your motherboard enabling you to add some more.
