Dear list,
Just a quick note to let you know I have almost
finished an implementation of an EHCI host controller for USB (usb-ehci.c) for
qemu. I am testing with an XP guest and so far I have a mass storage
flash key, a mouse and a tablet working. I haven’t yet implemented
isochronous or split transactions though. It doesn’t do companion
controller hand-offs for low or full speed devices either but Windows XP doesn’t
mind that I am attaching low/full speed devices through EHCI (I believe Linux
guests won’t like this).
I have asked the company I am working for to give me
permission to GPL the module and so far they are agreeable. So I am
planning to clean up and have an initial version for check in early in the new
year. If anyone has any inputs, please do let me know. I’m
new to qemu development so am not sure of checkin etiquette, etc.
Pointers in that regard appreciated too.
Cheers,
Mark
