800w USB disconnects

[rprockey]

I connect my Treo 800w to my work PC and my Laptop and I've noticed some odd behavior from the device, active sync and internet connection sharing. Sometimes when I move the device on my desk the Treo reconnects and Sync software re-initializes. Other times the device is just sitting there, connect and syncd, and out of nowhere windows reports that an unrecognized USB device was plugged in and active sync goes grey. With my Laptop, I'll fire up ICS on the device, teather it, and sometimes neither the Treo or the Laptop seems to recognize the connection. The laptop doesn't recognize and new hardware and (this is weird) on the Treo, the battery icon gets the bolt but the LED truns neither green nor red, it just remains off. I can unplug and plug back in and everything works as expected. Sometimes I have to repeat.

I've tried toggled "Enable advanced network functionality" but it has no effect.

I'm suspecting that something may be wrong with my USB cable or the device's USB port. After writing all of this out, It clear to me that I need to visit a Sprint Repair Center. Uhg.
