Yes, USB.
2 ports in the front and 2 in the back. I tried all 4 and nothing works.
I'm not sure what you call it but I have this thing you plug into one USB port and it gives you 4 USB ports. Only in 2 of the inlets the light on my mouse turns on but it still doesn't work. If I plug my mouse into any other USB ports my mouse light doens't come on.
On the back of the computer I also have 2 other inlets (mouse/ keyboard) with the older style plug. I found an older style mouse to plug in and this also doesn't work.
Since it is a work computer all the data was wiped out before they were given to the employees. I'm wondering if there was any sort of mouse driver that was wiped out?
