Hi,
This patch unfortunately is somewhat invasive, since makeing the qemu
usb core deal with this requires changes everywhere. This patch only
prepares the usb core for this, all the hcd / device changes are done
in such a way that there are no functional changes.
/me likes it.
When touching this _anyway_: How about making usb_handle_packet and
->handle_data callbacks return void (or bool for completed/async) and
expect drivers to fill the fields in USBPacket instead? That would kill
a little annonying difference in sync/async packet handling.
Ok, I've redone the patchset making usb_handle_packet and
the device's handle_control and handle_data methods return void, to
make the sync/async packet handling more alike.
This turned out to be quite a bit of work! But is all done now,
and it has been thoroughly tested (although with a subset
of all supported / emulated qemu usb devices, see the
commit message).
