Dear Customer,
Thank you for contacting Acer America. I apologize for the inconvenience that you have experienced. I suggest removing the USB drivers from the device manager and restart your computer. Here's how:
1. Unplug any devices you may have attached to the USB ports.
2. Click on Start, the right click on My Computer and choose Manage.
3. In the computer management window that opens, on the left side, choose Device Manager.
4. Look for the Universal Serial Bus Controller heading in the list on the right. Click on the + next to that heading.
5. Right click on item listed under this heading and choose uninstall. It may ask if you are sure you want to remove it, say yes.
6. After all items are removed, close that window and restart the computer. As it reboots, it will reinstall the drivers we just deleted. When it is completely started up, try your USB ports.
If this does not resolve the issue, please contact Acer Technical Support at 1-800-816-2237 Mon-Fri 7am-9pm CST and Sat-Sun 8am-5pm CST excluding holidays. Currently we are experiencing high call volume, so please expect your hold time to be longer than normal. It will help to expedite your call if you have the following information available in front of you when you call in: Your contact information, physical shipping address (no PO boxes are accepted), your Acer product.
