Arno Klenke has completed his work on the PCI and USB bus managers for Syllable. Not only does this simplify the internel managment of devices in Syllable, it also means USB UHCI support. The current implementation is a port of the Linux UHCI driver which has been re-written by Arno as a Syllable bus manager, and a native USB mouse driver.
