There are plenty of scenarios that don't use usb_drv, at least when ps2_drv is an option. run/demo, run/framebuffer, and run/ahci_bench are a few examples.

It looks like the Out_of_caps warning is common with usb_drv, and appears even when the driver is working properly.

This is interesting.  I get the same error message in a VirtualBox VM using the "ICH9" chipset.  (It doesn't happen with the "PIIX3" chipset, but the block device isn't found using that.)

How did you disable "usb_drv"?  (I tried a few things, but they all hung the system.)

No. I can use platform_drv just fine without usb_drv, and even with fb_drv.

    if you don't load the usb_drv, does the platform_drv still run out

        Also, I get the following message in dmesg on linux (from
        drivers/usb/host/pci-quirks.c), but not from usb_drv:
        QUIRK: Enable AMD PLL fix

        What might be going on? Why would usb_drv cause platform_drv
        to run out of CAPs, even when I assign it 2000 CAPs (instead
        of 800)?
