After spending several evenings exploring the motherboard of my Asus 701 (Eee) for USB signals and 5V (off in standby) hereís what Iíve discovered.

Thereís a 5V trace (off in standby) thatís available without draining current from the existing USB connectors - take a look at the picture above, snapped with my Sony Ericsson K850i (then scaled to 640◊480 and annotated).

There are 8 USB ports provided by the Intel chipset:
- 3 are the existing USB connectors
- 1 is used by the SDHC/MMC card reader
- 1 is used by the webcam
- 2 are used by the mini PCIe card slots (1 for each)
- 1 is still unknown (debug connector, perhaps?)

I damaged a USB Bluetooth module while looking for USB signals on the debug connector - doh! Consider this a warning

The MDC card slot does not have USB signals available, but both mini PCIe card slots doÖ

The Atheros mini PCIe wireless card does not appear to use USB signals (only PCIe signals):
