I followed the instructions posted in various places to enable my Nokia 770 to use a USB keyboard. In particular, here's what I did:

* updated firmware to version 3.2005.51-13 (European version)

* turned on default root access (via flasher utility)

* enabled USB host mode (via flasher utility)

* built a power supply and female connector for the USB bus by splicing the power cable and piping it through a 5V regulator

Each of these steps seems to have been successful in itself, but nothing happens when I plug in a USB keyboard. With my hardware hack in place, the USB icon appears in the upper righthand tray to indicate a "PC connection active," but this happens with or without the keyboard plugged in. Is there something I've missed? Is there somewhere in /sys/bus/usb I should be looking to check that the keyboard is at least recognized?

Thanks,
