Description Markus Armbruster 2013-08-26 14:06:10 UTC

The following USB host controller devices should be removed or made unavailable with -device / device_add:

name "exynos4210-ehci-usb", bus System
name "xlnx,ps7-usb", bus System
name "vt82c686b-usb-uhci", bus PCI
name "piix4-usb-uhci", bus PCI

How reproducible:
Always

Steps to Reproduce:
1. for X in the above devices: -device X

Actual results:
-device X is accepted

Expected results:
-device X is rejected, just like -device nonexistant

Additional info:
Equally unwanted pci-ohci, sysbus-ohci are tracked seperately (bug 903914).

Comment 3 Markus Armbruster 2014-04-29 12:00:15 UTC

The time for cutting unwanted devices has passed.  We'll have to live with these, just as in RHEL-6.

Comment 4 Markus Armbruster 2014-07-29 13:04:25 UTC

Clarification on WONTFIX: "exynos4210-ehci-usb" and "xlnx,ps7-usb" are actually gone (fix for bug 1001216 got rid of them).  Only "vt82c686b-usb-uhci" and "piix4-usb-uhci" are still around.
