[Qemu-devel] [PATCH 19/20] xhci: fix control xfers |
Date: |
Wed, 7 Mar 2012 14:05:19 +0100 |
Use the new, direct control transfer submission method instead of
bypassing the usb core by calling usb_device_handle_control directly.
The later fails for async control transfers.
This patch gets xhci + usb-host combo going.
