Pantech UM175 modem problems??
  • gamfaspats1gamfaspats1 January 2010
    I use a Pantech UM175 usb modem to connect to my mobile broadband provider and I am having problems with it in Slitaz.
    I am using Slitaz 2.0. When I plug the modem into a port on other distros, the device /dev/ttyACM0 is created. I can then set up a ppp connection using that device and connect. This doesn't happen in Slitaz. When I plug it in while booted into Slitaz, I get the following msg. in the error logs.

    user.err kernel: hub 2-0:1.0: unable to enumerate USB device on port 2
    user.info kernel: usb 6-2: new full speed USB device using uhci_hcd and address 2
    user.info kernel: usb 6-2: configuration #1 chosen from 1 choice

    What am I missing here?

    This package is required for usb wifi/dialup modems

    tazpkg get-install usbutils

    follow that with

    lsusb

    then

    tazhw detect-usb

    Wish I could help more but I've never setup one of those devices.

    Please post back with how you got it to work.

    Thanks

    I have been able to get it working....

    I installed the usbutils package (I wondered where the lsusb command was) and here is the output from lsusb and tazhw detect-usb...

    lsusb can see the device...it's the device...

    "Bus 002 Device 005: ID 106c:3714 Curitel Communications, Inc."

    but Siltaz still could not work with it. Still no /dev/ttyACM0. I then did a Google Linux search on "ttyACM0" and found that the module cdc_acm has to be loaded. So, it appears that the problem is that SliTaz does not realize that device needs the cdc_acm module. After I modprobe that module, the /dev/ttyACM0 device is created and things start working.

    Where is the proper place in the SliTaz boot scripts to load the cdc_acm driver?
  • mojomojo January 2010
    To load modules from gui

    subox tazctrlbox
    Initialization tab , add cdc_acm with a white space to

    Load Modules:

    click the Change button

    The file your configuring is /etc/rcS.conf

    To do it with a text editor add to LOAD_MODULES=

    Found some 3G modem tazpkgs that may be of use

    Thanks for your helpful feedback.

    I checked out the 3G packages you referenced and the usb_modeswitch doesn't work with my modem. I checked the web site for that app. and my modem isn't listed. The other two apps. are just ppp dial-up apps I believe. I use scripts written by Sierra Wireless for cdma devices. I just key in "pppd call cdma" and I am connected.

Howdy, Stranger!
