Okay, so i'm trying out the usb host mode on my n770 running OS 2006, but the 770 isn't recognizing anything. The OS itself is newly flashed, so it's pretty clean. I have enabled r&d-mode and usb-host-mode through the flasher. Hardware wise, i'm running a modified radio shack 4-port powered usb 1.1 hub. I desoldered the upstream port and one of the downstream ports. I connected the two upstream data lines and the two downstream power lines to the 770s USB connector (following the pinout, of course). I get absolutely no response when a thumb drive is plugged in, not from the hub (it has activity lights), nor the 770. All of the hardware components have been tested individually and they all work fine, and i'm pretty sure it's not a soldering error.

I assume I have some drivers to install, but I honestly have no idea where to go from here.
