I have installed an USB hub inside my aspire one. The hub I used was
A-link HUBU4. There is now two internal USB ports behind the 3G modem hatch (idea stolen from eeeuser.com

). Here are some photos:

The hardest part was to unsolder USB connectors from USB hub without damaging the soldering pads on the PCB. When I was unsoldering the last connector, I accidentally removed one of the soldering pads, and when I tested the hub there was an "unknown device" in the device manager. I managed to fix that by soldering a small jumper wire to the hub's PCB (you can see it on the image below). I also needed to remove the crystal oscillator temporarily from the center of the PCB.

All wires soldered and added some glue from a hot glue gun.

My original plan was to route the internal USB webcam wires through the USB hub, but I found it too difficult to do (I think that four wires on the right of the connector belongs to the webcam, not sure though).

Second plan was to route the wires from external usb port so that the external port remains usable, but finally I gave up and soldered the wires directly to the USB port. Well, two external ports should be enough for everybody


USB ports in place.

The hub fits nicely inside the aspire. I attached it with a very strong douple sided tape.

8GB USB flash drive and Trust USB bluetooth adapter in the 3G modem slot.

Windows XP recognized the hub and the attached devices.
