Hi All,

Finally I was able to pin-point the issue.

Just in case ones needs this.

ovirt by default enables USB 1.0 controller.

To enable USB 2.0 controller go to

At ovirt engine at config file below, change the controller from piix3-uhci to piix4-uhci as below:

piix4-uhci is still USB1 controller

the one we use is still the most compatible default, we do not test any other (other than set of USB2 and USB1 companions when using SPICE)

you’re welcome to overwrite it (not by changing the defaults which gets overwritten on upgrade, but rather extending it by your custom properties, ideally per OS type where you need that change)

You can use all the QEMU supported controllers, e.g. xhci if you want USB3 

Thanks,

michal

/etc/ovirt-engine/osinfo.conf.d/00-defaults.properties

os.other.devices.usb.controller.value = piix4-uhci

then restart engine:
systemctl restart ovirt-engine

USB device then is attached successfully at Windows VM.

Hi All,

I have Ovirt 4.1 with 3 nodes on top glusterfs.

I Have 2 VMs: Windows 2016 64bit and Windows 10 64bit

When I attach a USB flash disk to a VM (from host devices) the VM cannot see the USB drive and report driver issue at device manager (see attached). This happens with both VMs when tested.

When testing with Windows 7 or Windows XP USB is attached and accessed normally.

Have you encountered such issue?

I have installed latest guest tools on both VMs.

Many thanx
