Hi,
I want to share a mod that I did yesterday on the w500gp.
I wanted to add an internal 2,5 HD into the w500gp.
So I bought a USB/ide interface(already had a 2,5 80Gb disc) and decided to try to see how I might
insert the HD into the case.
The next challenge was to see If I could use the internal USB ports on the VIA VT6212L ( which is a PCI USB 2.0 Controller chip).
There are 4 USB ports on that chip and only two are connected.
So I got the Data sheet and found a couple of solder points to try out. USBP4+ and USBP4-.
See attach 1
Data sheet:

I soldered the VCC and GND to one of the existing USB connections.
As long as the device uses 100ma i think it will be fine. Else I would think that the port will be closed(according to USB spec.).
See attach 2
I did the soldering and I needed to actually get external power to the HD from the 5v connection in the 500gp directly and that worked fine. Couldn't get it to work from the USB connection directly.
So this configuration seems to work and the final product looks like attach 3.
Cheers
/P
