Problem attaching USB keyboard

[Philipp]

Hi everyone,

the following problem occurs on the amd64 version of

	FreeBSD 9.2-RC4,
	FreeBSD-9.2-PRERELEASE-20130831-r255108,
	FreeBSD-10.0-ALPHA2, and
	FreeBSD-10.0-CURRENT-20130907-r255342.

I simply can't use my keyboard (Lenovo Prefered Pro USB). I used the
FreeBSD memstick ISO to install the system. I had no problems using
the keyboard within the memstick version (bsdinstall, and so on). But on
the installed copy of FreeBSD I get the following error when I try to
attach the keyboard:

usb_alloc_device: device init 2 failed (USB_ERR_IOERROR, ignored)
ugen0.2: <Unknown> at usbus0 (disconnected)
hub_reattach_port: could not allocate new device

I had to set debug.acpi.disabled to "hostres" on all version, in order
to boot the system. [1]

This error does not occur on 9.1-RELEASE.

Mainboard: Intel DQ87PG (Keyboard is connected via the USB 2.0 port)
RAM: 32 GB
