Description Hans de Goede 2013-11-21 14:41:58 UTC

USB-3 has a new feature called bulk-streams. Bulk stream support is necessary to add full USB-3 support for the usb-redirection code for qemu.

Note bulk-streams support requires kernel and libusbx changes (for usb-host) and usbredir (for usb-redir) changes to be in place before it can be added to qemu.

My current qemu tree has patches to add it (tested with a locally build kernel, libusbx and usbredir):
http://cgit.freedesktop.org/~jwrdegoede/qemu/log/

Work to get this upstream is in progress, the kernel patches are scheduled to go into 3.14, once those are in place the rest can be pushed upstream pretty quickly.

Planning for 7.1, imho not important enough to squeeze into 7.0 post-beta.

Agreed, that was my intention all along, esp. since some bits are not upstream yet.
