I'm currently not able to use any USB devices on my computer I have tried quite a bit of things.
1. system restore back to when they were working, temporary fix stopped working after that
2. uninstalled all usb controller as well as the usb x hci compliant host controller
3. updated everything windows recommened and required in windows update
4. install the bluetooth, card reader, and chipset driver from the acer website according to my model still is not working. Bluetooth doesn't work either.
