Express randomly disconnecting from computer

Hey guys, need help with a problem with my sansa express. When it’s plugged into my usb it randomly disconnects and reconnects constantly. Doesn’t matter if I’m transferring or just charging. I have tried the soft reset, and found a post that gave instructions on how to prevent your computer from limiting power output to the usb port but it is still happening. It hasn’t really ruined anything yet, just more of a general annoyance.

Thanks for any help.

I had this issue with one of my older computers… I found it easier to just get a USB hub with it’s own power supply…
