Hi Mathias && Balbi and ALL,
We hit one hang issue when using DWC3 XHCI host mode to play Video
for Isochronous transfer.
Both usb-audio module and XHCI driver output errors.
Our kernel version is 3.18.x.
And already include Mathias's commit:

Hi ALL,
One question for you guys,
does the current kernel USB stack support H264 USB camera by default?
Did some basic check but not found clear result.
Help will be very appreciated!
Thanks!

Hi Greg,
Thanks for quick reply.
Actually we are now only planing to do such device which support H264,
but we wonder if the kernel USB host stack can support such case.
Thanks!
