    Exclamation EVDO Datacard not recognized (Anydata ADU-520A)

    Dear All,

    I used to connect my computer with a EVDO data Card (Anydata ADU 520A) without problem on 9.04

    Since update to 9.10, the datacard is not recognized and it's not possible anymore to connect.

    Can you provide help?

    Hi, golgot04!
    Probably this howto works not only with 10.04, but also with 9.10
    Edit system udev rules file:
    sudo gedit /lib/udev/rules.d/61-option-modem-modeswitch.rules
    and comment the line with #:
    ATTRS{idVendor}=="05c6", ATTRS{idProduct}=="1000", RUN+="modem-modeswitch -v 0x%s{idVendor} -p 0x%s{idProduct} -t option-zerocd"
    install special usb-cdrom to usb-modem mode switching software:
    sudo apt-get install usb-modeswitch usb-modeswitch-data
    create a new kernel driver parameter file
    sudo gedit /etc/modprobe.d/usbstor.conf
    and plache this text into:
    options usb-storage option_zero_cd=2 delay_use=5
    Reboot the system (or umount all flash drives plus execute a command: modprobe -r usb_storage;modprobe usb_storage).
    Plug AnyData 520A device into usb port wait about 10-20 seconds, check /dev/ttyUSB* devices / or NetworkManager Mobile broadband device)
