Sorry, but this is wrong! I have the same problem with an USB extension cable. When you insert the extension cable, a new entry appears in the device manager labeled "USB 2.0 Hub". Unfortunately, Windows 7 is unable to find a suitable driver for it. The same cable works with XP, which is able to find the right driver...
If this can help!
Also, I would be interested if someone has found the right driver for Seven!
