G900 possible cable issue

I've had my G900 for 1-2 years. Recently, perhaps for a few months, I've had an issue with increasing frequency. Sometimes the mouse will cease working, and I'll hear the audio cue of a USB device being unplugged. Count to five and it works again, but it really screws me over during games.

I'm not sure if it's cable or port related, or something completely different. Note that I've almost always used the mouse exclusively with the cable. It's hard to imagine the cable having been damaged with the way I have my stuff set up, but you never know. Switching ports haven't had any effect.
