[Qemu-devel] USB EHCI development nearing completion

[Mark B]

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
