Red Hat Bugzilla – Bug 1001113
Disable or remove USB host controller devices we won't support
Last modified: 2014-07-29 09:04:25 EDT
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
Steps to Reproduce:
1. for X in the above devices: -device X
-device X is accepted
-device X is rejected, just like -device nonexistant
Equally unwanted pci-ohci, sysbus-ohci are tracked seperately (bug 903914).
The time for cutting unwanted devices has passed. We'll have to live with these, just as in RHEL-6.
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.
