Similarly, you will need to recompile any ports you may have using ugen*. I don't know what your main problem is though - the patchset works well for me, but I don't normally use USB mice. I just stole one off a windows machine, and I can reproduce the problem - if the mouse is plugged in, the kernel appears to hang on boot after probing uhub0, but after waiting about 30 seconds it logs "uhub0: device problem, disabling port 1" and then successfully probes the LPT adaptor plugged in to the other hub port. Once booted, there are regular errors logged every few seconds until I unplug the mouse: uhub0: device problem, disabling port 1 uhub0: port error, restarting port 1 I am not sure that this problem is down to mouse support as such; I don't have ums in my kernel, and things have gone wrong before usbd has had a chance to auto-load it. Maybe it's support for low-speed devices in general that is broken? Unfortunately I don't have any other low speed devices to test this theory; all my keyboards are PS/2.
