Thumb drive not recognized in two of three ports

Hello, I have an Acer 5230E-2177 which has a usb port in back that if I plug in my thumb drive I can get all my files. But if I plug into either of the usb ports on left side nothing happens. Went to Device Management by way of Computer:Manage, and only three drives show up usually which are: Recovery Partition, Acer C: , System Reserved Also, when I look at drives in Computer I get C: and D: (DVD) and if I plug in the thumb drive into back USB I get E:. So why don't the two USB ports on side work? Thanks

Hi Maxie, I only have three usb ports on my laptop. The thumb drive works just fine on back usb one but nothing on the side two which may be a usb 2.0 (maybe) because when I plug the thumb drive in back it says there is a faster usb to plug into. I just unplugged my wired mouse and plugged into one of side ports. A notice popped up if I can remember which said wasn't recognized or driver not installed. So I tried updating driver in Driver Manager. Didn't work. Then I uninstalled driver and rebooted and still says USB DEVICE NOT RECOGNIZED When I plug in thumb drive into side port, I get no notice of wrong driver or Device not recognized. Thanks

Hi Maxie, I have the ScreenShot saved to desktop but none of the formatting buttons including the paperclip to attach the file will work. Not sure why Sorry for trouble...

Hi Maxie, There was a yellow triangle with exclamation when the mouse was plugged in. Not when thumb drive plugged in. USB ports are not blue. Thanks. When I plugged mouse into the back usb port the yellow exclamation went away.

Is the model number something other than Acer 5230E-2177 in first post?
