Front USB might not be able to provide sufficient power to run your Pendrive.

Front USB are mostly not USB 3.0. But they should work with USB 2.0 speeds.
My pc has usb 2.0 ports but it aint recognizng my usb drive

The front usb port of my acer pc won't recognize usb3.0 drives most of the time. I have to slightly pull out/push in the drive to get it detected. Looks like a problem with loose contact.
You are a lifesaver man, it worked

thanks
