have this weird problem that i realised today. been connecting usb #1 for my laptop cooler and #2 for my usb dongle (prolink wireless mouse). so today when i tried to connect my usb dongle on my #1 usb port it just cant detect my mouse at all. it works fine when i use the dongle on my #2 usb port. i tried using a thumbdrive on #1 use port and it works so i dont know whats the problem here. can anyone give any solution? *theres no driver to download for my mouse online and i never install windows on my mbp.
