N410C WiFi USB W200 Multiport Modification ZD1211B

Hi there!

I'm trying to add USB WiFi module instead of original W200 multiport
module. I bought WiFi with ZD1211B chipset. It's working great when
plugged to the normal USB 2.0 port on the side of laptop. When
attached to multiport connector, windows reports unknown device
So, I decided to sacrifice one of the USB2.0 ports on the docking
station. Basically these "docking station" usb connectors
are routed through docking station connector from the bottom side of
the notebook's motherboard. I found the correct pins and soldered two
wires on it.

Result? I tryied to connect my USB wifi module to it and it is
completely silent, nothing happening. When plugged to the docking
station's usb port, works fine - even with wires connected to the
motherboard. I have checked with the scope that the signals on the
usb wifi module D+ and D- are the same as on my wires. For the moment
I'm completely unsure why it is not working. I'm taking power for usb
wifi module from original multiport connector. Any ideas?
