Is it possible you are running into this warning from the kernel documentation, cxacru-cf.py? # Warning: cxacru-cf.bin with MD5 hash cdbac2689969d5ed5d4850f117702110 # contains mis-aligned values which will stop the modem from being able # to make a connection. If the first and last two bytes are removed then # the values become valid, but the modulation will be forced to ANSI # T1.413 only which may not be appropriate. # # The original binary format is a packed list of le32 values. And this about a change in the firmware from cxacru.txt 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: I didn't look deep enough to determine what the error codes mean (-104), (-32). They could be because of the above. This might answer your request to simulate unplug/plug. 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) _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
