		device.  This is useful to ensure auto probing won't

		match the driver to the device.  For example:

		# echo "046d c315" > /sys/bus/usb/drivers/foo/remove_id

What:		/sys/bus/usb/device/.../avoid_reset

Date:		December 2009

Contact:	Oliver Neukum <oliver@neukum.org>

Description:

		Writing 1 to this file tells the kernel that this

		device will morph into another mode when it is reset.

		Drivers will not use reset for error handling for

		such devices.

module loaded, the device will sometimes stop responding after unloading the

driver and it is necessary to unplug/remove power to the device to fix this.

Note: support for cxacru-cf.bin has been removed. It was not loaded correctly

so it had no effect on the device configuration. Fixing it could have stopped

existing devices working when an invalid configuration is supplied.

There is a script cxacru-cf.py to convert an existing file to the sysfs form.

Detected devices will appear as ATM devices named "cxacru". In /sys/class/atm/

these are directories named cxacruN where N is the device number. A symlink

named device points to the USB interface device's directory which contains

* adsl_headend_environment

	Information about the remote headend.

* adsl_config

	Configuration writing interface.

	Write parameters in hexadecimal format <index>=<value>,

	separated by whitespace, e.g.:

		"1=0 a=5"

	Up to 7 parameters at a time will be sent and the modem will restart

	the ADSL connection when any value is set. These are logged for future

	reference.
