Follow-up Comment #2, bug #55288 (project grub): I just downloaded XCP-NG and it freezes at the GNU GRUB.
I have a small server with only USB 3.0. When I disconnect the keyboard, there's no problem booting and I can reconnect the keyboard and it works.

Once I pass by grub, Linux kernel has no issues and Windows on different laptop has no issues with hub and keyboard.(hence why I got it, i got 6 ports used up, more than laptop has, plus i change hub between home pc and work PC, so i can reuse my nice webcam/soundcard/mouse/keyboard/etc) > > I can do extra tests to isolate issue to either hub or to keyboard (I have second keyboard somewhere in the house). > And I suspect its USB1.1 or 2 or whatever the hell it is, with USB3 host controller. > > Grub reliably hangs the moment count down and rest of non graphic interface is visible.
