			Description:
			A raw device name of a disk does not always point a same disk
			each boot-up time. Therefore, users have to use persistent
			device names, which udev creates when the kernel finds a disk,
			instead of raw device name. However, kernel doesn't show those
			persistent names on its messages (e.g. dmesg).
			This file can store an alias of the disk and it would be
			appeared in kernel messages if it is set. A disk can have an
			alias which length is up to 255bytes. Users can use alphabets,
			numbers, "-" and "_" in alias name. This file is writeonce.

			What: /sys/bus/pci/drivers/ehci_hcd/.../companion
			/sys/bus/usb/devices/usbN/../companion
			Date: January 2007
			KernelVersion: 2.6.21
			Contact: Alan Stern <stern@rowland.harvard.edu>
			Description:
			PCI-based EHCI USB controllers (i.e., high-speed USB-2.0
			controllers) are often implemented along with a set of
			"companion" full/low-speed USB-1.1 controllers. When a
			high-speed device is plugged in, the connection is routed
			to the EHCI controller; when a full- or low-speed device
			is plugged in, the connection is routed to the companion
			controller.

			Sometimes you want to force a high-speed device to connect
			at full speed, which can be accomplished by forcing the
			connection to be routed to the companion controller.
			That's what this file does. Writing a port number to the
			file causes connections on that port to be routed to the
			companion controller, and writing the negative of a port
			number returns the port to normal operation.

			For example: To force the high-speed device attached to
			port 4 on bus 2 to run at full speed:

			echo 4 >/sys/bus/usb/devices/usb2/../companion

			To return the port to high-speed operation:

			echo -4 >/sys/bus/usb/devices/usb2/../companion

			Reading the file gives the list of ports currently forced
			to the companion controller.

			Note: Some EHCI controllers do not have companions; they
			may contain an internal "transaction translator" or they
			may be attached directly to a "rate-matching hub". This
			mechanism will not work with such controllers. Also, it
			cannot be used to force a port on a high-speed hub to
			connect at full speed.

			Note: When this file was first added, it appeared in a
			different sysfs directory. The location given above is
			correct for 2.6.35 (and probably several earlier kernel
			versions as well).
