tnkgrl spent some time exploring the motherboard of her Eee PC. Looking for available USB ports, she was able to hijack the USB trace that goes to the mini PCIe slot used by the Atheros wireless card. Since the Atheros doesn’t use the USB signal, the card will still function without it. This gives you a spare USB port, perfect for embedding a tiny USB Bluetooth module!

If you don’t mind soldering a few traces, you can add a built-in bluetooth device to your Eee PC. You’ll still have the external ports available for other devices, and your wireless card will still function. The only difference is that when you can’t find a hotspot, you’ll be able to get a cellphone uplink and jack in using your new bluetooth connection.
