I would guess that usbohcd.sys was the cause of your system failing to 
boot when using the usbhcd11 build.

Builds 8 through 11 inclusive failed to boot here with the problem 
resolved by reinstalling the IBM usbohcd.sys driver.

However, using usbhcd12 drivers the system is booting fine and working 
with the only usb1 device I have - a trackball.
