Had the problem where the Supermicro IPMI keyboard wouldn't work on some

Turns out adding the following to loader.conf does fixes the issue:

So the question is why would this help?

Surely disabling one controller shouldn't make devices attached to
another work?


The USB device is failing to enumerate. Are you sure there is no XHCI
controller on this device?
I did try removing xhci from my kernel config, but that had no effect,
only when I disabled the ehci controller did it correctly enumerate the
devices attached to the uhci controller.

Attached is the outuput from pciconf -l -v in case that helps. If
there's anything else I can provide which will help just let me know.

For reference I'm currently testing 10.1-RC4 on this box.


Maybe you can check the PCI IDs with Linux EHCI driver, if your hardware requires some special quirks?
I cant find any mention of quirks for the Intel USB controller PCI IDs but I might be looking in the wrong place, do you have a link to what I should be searching though?

I did however find the following which is for the exact device I'm having issues with and seems to indicate the HW might have an issue with HighSpeed mode.


Which makes me wonder if hw.usb.ehci.no_hs=1 would also result in a working device.
