[Qemu-devel] [PATCH 0/7] usb: packet pipelining

[Gerd Hoffmann]

  Hi,

After a bunch of usb core restructions since release 1.0, this patch
series now puts the last bits into place, then flips the big switch.
usb can do pipelining now, i.e. have multiple usb transfers in flight
the same time.

Pipelining is supported by usb-host, uhci and xhci.  ehci can't handle
it yet.  Great opportunity to check out xhci ;)

The patch series features some xhci bugfixes too, with them applied xhci
and usb-host play alot better together.

please test & review,
  Gerd
