Default Minimal kernel options for USB keyboard?
I have a USB keyboard, printer and mouse which are working under GENERIC. At startup it probes a bunch of USB stuff and takes for ever so I would like to remove everything but those devices from the kernel.

I tried just these devices:
uhci, ehci, sb, ukbd, ulpt, ums.

But it hangs on startup with this:

Code:
Root mount waiting for: usbus4
It just hangs there and gives that message every few seconds. My fstab only has one device, my root drive (SATA).

Possibly looking for USB disks, which need at least a couple of SCSI devices:
Code:
device scbus
device da
device pass

Thanks, but is there any way to disable that probing? I'll never have a USB disk and takes a while (even in GENERIC) for all the USB stuff to come up.

Hmm. Try this:
/boot/loader.conf
Code:
hw.usb.no_boot_wait="1"

Thanks. I tried that and also turned on USB Debugging. Same thing happens. It doesn't really give any indication on what's going on. Just the same message over and over. Any other tips?

Here is dmesg | grep -i usb:

Sorry, I've got no other ideas. The freebsd-usb mailing list is likely to have better answers.

Ok, thanks. This can be marked as solved. I don't think it was a USB problem at all, but had SCSI_DELAY set to 0. Setting that to 2000 or higher fixes it. This can be closed.
