With my latest USB patches, that I just sent out, UHCI support is probably as good as it gets. I tested all kinds of devices with Linux and XP guests and things are solid. Host USB is now fully async and I do not see any delays/jerkiness anymore.
However, overall performance can certainly be improved by supporting EHCI (ie usb-2.0 stuff). For example native performance of an external USB hard drive is ~28MB/sec (measured with hdparm). The same drive attached to the Linux guest gives me about 500KB/sec. Huge difference. So I'm going to start working on EHCI (starting tomorrow). If somebody has any EHCI code I can use let me know.
