Description of problem: Only support the usbdk driver in RHEV-M 4.0 or newer. The usbdk driver supports more devices than usbclerk (WinUSB). Also usbdk is installed once using an MSI installer. UsbDk is supported since RHEV-M 3.6
oVirt 4.0 Alpha has been released, moving to oVirt 4.0 Beta target.
Will 4.0 UsbDk installer also replace usbclerk installations (and possibly old redirector installations), to ease the transition?
(In reply to David Jaša from comment #4) > Will 4.0 UsbDk installer also replace usbclerk installations (and possibly > old redirector installations), to ease the transition? No, users would need to remove it manually. If both usbclerk and usbdk are installed, usbdk is to be used for spice usbredir by remote-viewer.
