I compared the Qemu USB controller with the Bochs one using Ralph Brown's pcifg utility and found two different things. - Bochs USB appears at function 2 of the PIIX3 - Bochs USB uses PIRQ line INTD You can find both things in the PIIX3 documentation. I tried the Qemu USB implementation with Win98 here. The hubs are detected correctly, but it makes Win98 hang on shutdown. > - Linux host USB redirector to use the USB 1.1 host devices which are > not requested by the host OS (i.e. no host driver is loaded for them). > It is *very* limited and buggy at the moment, but I was able (once !) to > mount a disk-on-key flash device. I guess the host OS doesn't like modifing data on a mounted devices. It might be okay for input-only devices. I cannot try it here, since it requires root permissions. -- Bye Volker _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
