+Description:
+ EVM protects a file's security extended attributes(xattrs)
+ against integrity attacks. The initial method maintains an
+ HMAC-sha1 value across the extended attributes, storing the
+ value as the extended attribute 'security.evm'.
+
+ EVM depends on the Kernel Key Retention System to provide it
+ with a trusted/encrypted key for the HMAC-sha1 operation.
+ The key is loaded onto the root's keyring using keyctl. Until
+ EVM receives notification that the key has been successfully
+ loaded onto the keyring (echo 1 > <securityfs>/evm), EVM
+ can not create or validate the 'security.evm' xattr, but
+ returns INTEGRITY_UNKNOWN. Loading the key and signaling EVM
+ should be done as early as possible. Normally this is done
+ in the initramfs, which has already been measured as part
+ of the trusted boot. For more information on creating and
+ loading existing trusted/encrypted keys, refer to:
+ Documentation/keys-trusted-encrypted.txt. (A sample dracut
+ patch, which loads the trusted/encrypted key and enables
+ EVM, is available from http://linux-ima.sourceforge.net/#EVM.)

+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).
