-Firmware is required for this device: http://accessrunner.sourceforge.net/
-
-While it is capable of managing/maintaining the ADSL connection without the
-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
-several sysfs attribute files for retrieving device statistics:
-
-* adsl_controller_version
-
-* adsl_headend
-* 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.
-
-* downstream_attenuation (dB)
-* downstream_bits_per_frame
-* downstream_rate (kbps)
-* downstream_snr_margin (dB)
-	Downstream stats.
-
-* upstream_attenuation (dB)
-* upstream_bits_per_frame
-* upstream_rate (kbps)
-* upstream_snr_margin (dB)
-* transmitter_power (dBm/Hz)
-	Upstream stats.
-
-* downstream_crc_errors
-* downstream_fec_errors
-* downstream_hec_errors
-* upstream_crc_errors
-* upstream_fec_errors
-* upstream_hec_errors
-	Error counts.
-
-* line_startable
-	Indicates that ADSL support on the device
-	is/can be enabled, see adsl_start.
-
-* line_status
-	"initialising"
-	"down"
-	"attempting to activate"
-	"training"
-	"channel analysis"
-	"exchange"
-	"waiting"
-	"up"
-
-	Changes between "down" and "attempting to activate"
-	if there is no signal.
-
-* link_status
-	"not connected"
-	"connected"
-	"lost"
-
-* mac_address
-
-* modulation
-	"" (when not connected)
-	"ANSI T1.413"
-	"ITU-T G.992.1 (G.DMT)"
-	"ITU-T G.992.2 (G.LITE)"
-
-* startup_attempts
-	Count of total attempts to initialise ADSL.
-
-To enable/disable ADSL, the following can be written to the adsl_state file:
-	"start"
-	"stop
-	"restart" (stops, waits 1.5s, then starts)
-	"poll" (used to resume status polling if it was disabled due to failure)
-
-Changes in adsl/line state are reported via kernel log messages:
-	[4942145.150704] ATM dev 0: ADSL state: running
-	[4942243.663766] ATM dev 0: ADSL line: down
-	[4942249.665075] ATM dev 0: ADSL line: attempting to activate
-	[4942253.654954] ATM dev 0: ADSL line: training
-	[4942255.666387] ATM dev 0: ADSL line: channel analysis
-	[4942259.656262] ATM dev 0: ADSL line: exchange
-	[2635357.696901] ATM dev 0: ADSL line: up (8128 kb/s down | 832 kb/s up)
