[Qemu-devel] USB: 2 bug-fixes, for master *and* for stable-1.1

[Qemu-devel] USB: 2 bug-fixes, for master *and* for stable-1.1

[Hans de Goede]

Here are USB 2 bug-fixes, please also cherry-pick these into the
stable-1.1 branch, esp. the second one as that fixes an easily triggerable
assert.

Note these patches are against 1.1.0, not against master, but they are relevant
for, and should apply to, master too.

Regards,

Hans

[Qemu-devel] [PATCH 2/2] usb-ehci: Fix an assert whenever isoc transfers are used

[Hans de Goede]

hcd-ehci.c is missing an usb_packet_init() call for the ipacket UsbPacket
it uses for isoc transfers, triggering an assert (taking the entire vm down)
in usb_packet_setup as soon as any isoc transfers are done by a high speed
USB device.
