Hi,
I'm running Xen v4.9 on DRA7 (OMAP5/ArmV7) with Linux kernel v3.14 (yikes!!) on
dom0 and domU.
I'm struggling to get USB passthrough working using pvUSB.
My domU config file contains
usb = 1
usbctrl = ['type=qusb,version=2,ports=4', 'type=qusb,version=1, ports=4', ]
I can see the vusb-0 and vusb-1 platform devices in /sys/devices
And the following message on domU kernel log
[ 1.849572] xenbus_probe_frontend: Device with no driver: device/vusb/0
[ 1.849627] xenbus_probe_frontend: Device with no driver: device/vusb/1
This means that there is no device driver for the vusb host controllers.
What is the way forward? Do I need to apply some patches to the domU kernel to
add support for the USB frontend HCD drivers?
This is one mandatory step, yes. You'll need:

The question is whether this will be enough for you to make it work: the
pvusb backend is qemu based. I'm not sure this will just work on ARM.
Backends in QEMU should just work with ARM. Although, I haven't tried
the PVUSB one.
