Long answer: There is no usb3 support in RHEL-6, and that isn't going to change. Closing. Target for RFE's is RHEL-7. Should things not work on RHEL-7 feel free to file a RFE (or reopen this bug & move to RHEL-7). Whenever the usb3 pci card is bootable or not doesn't matter at all (unless you pci-assign host controller to the guest). Problem most likely is that some quirks must be applied to the usb descriptors when attaching a usb3 device to the guests usb2 controller. On RHEL-7 those quirks are present and there also is a virtual xhci (usb3) controller you can use instead of ehci (usb2) for better compatibility with usb3 devices.

Tried SL7. I liked it a lot. But I had to rip it out as it does not support Wine 32, which is a complete and total deal killer. Total pity, as I thought EL 7 was really sweet, although useless as a workstation. > Long answer: > > There is no usb3 support in RHEL-6, and that isn't going to change.

Well, hopefully those actually able to upgrade to RHEL 7 will benefit from this. Thank you for considering it. -T |
