Sorry for the wall of text, just wanted to give a little back story, might help a little bit:
The company I work for builds computerized inventory control machines, and I've semi-recently been moved to building and imaging computers. We stick a flash drive inside of the computers to back up the core files for our program, the flash drive is plugged in to an internal USB expansion. We've been having read/write errors and discovered that the internal ports are only putting out 3.3v rather than 5v like the front and back panel ports. We slowed down the USB ports from 2.0 to 1.1 and the back up/restore works fine, albeit very slowly. The controller is linked to the front panel ports though, which could cause issues with the thumb print readers, proximity readers, etc. We are trying to find a flash drive that can operate at only 3.3v rather than use the more expensive solution one of our engineers came up with. (Sucking additional power out of the second SATA port for the USB wires)
If you know anything about this sort of thing your help would be much appreciated. Is it possible, or will we have to use the second wire? We can't put the flash drive on the outside because we need as many external ports open as possible.
