[SOLVED] 3G modem not visible as /dev/ttyUSBX

Aldebaran · 01-26-2011, 02:12 PM

Hi.
I'm currently trying to get my Option 0505 3G modem to work in Slackware 13.1.
My Problem is that when I plug the device in no /dev/ttyUSBX appears.
I're read quite a few threads as to connect these modems, but none seems to cover my problems.

This is my dmesg after plugging in:

PHP Code:

usb 1-1: New USB device found, idVendor=0af0, idProduct=d055

CE: hpet increasing min_delta_ns to 33750 nsec

I then try "#modprobe option", and get output for dmesg:

PHP Code:

I'va also tried to prevent the hso module to load by blacklisting it, and only use the option module, but without any luck.

This is #lsusb:

I've also set the usb_modeswitch to logging, this is my /var/log/usb_modeswitch:

As far as I can deduct anything from the usb_modeswitch log, it seems to be able to find the device and switch it, but something else outside is not able to create the /dev/ttyUSBX link.

I'm using the 2.6.33.4-smp kernel that came with the distro.

Ah, one more thing: when i uninstall usb_modeswitch and plug in the 3G modem, it is recognized as a usb memory stick.

The computer is a Lenovo Ideapad S10-3.

Some (alot) of this info may be of no use, but I hope someone may present a solution to my existential, all consuming problem....

Best regards

Your device should be handled without issue. It appears that udev is detecting the device but that usb_modeswitch is unable to access the serial modem port. Perhaps this is relevant.

From http://www.draisberghof.de/usb_modeswitch/#hardware

Quote:

Annother way of influencing the kernel behaviour is the parameter "delay_use" of "usb-storage" which sets the time in seconds after plugging when the storage device will actually be used (and probably automounted). The default value is 5; this might affect the switching result under certain conditions.
To change the default add in /etc/modprobe.conf:

options usb-storage delay_use=1 (or 10, or other)

Hi

You don't need your modem to show as ttyUSBx. Option modems show as ttyHSOx and the corresponding hsox interface is used instead of pppx; all you need seems to be there:

Thanks for good replies.
As You mentioned the device came up as /dev/ttyHS0 thru /dev/HS3.
I read further and came over an article that suggested to do: #ln -s /dev/ttyHS0 /dev/modem.

This because the KPPP does not have /dev/ttyHS0 as an option in modems.
I've not been able to get the HSOconnect up and running yet. And as far as i know its possible to use the KPPP.

So when i start the KPPP, after setting it up, it states that the modem is found, and ready, but I get an error when dialing:

PHP Code:



ATZ 
OK 
ATM1L1 
OK 
ATDT*99# 
ERROR

I'm guessing it's caused by a minor error in the set up of KPPP. Anyone know how to set this up?

As far as my original question is concerned, I know it's solved, but I'll wait a few hours to see if this last minor problem also gets solved before I change the status.

Best Regards

Follow the manual, should be ok. I haven't been using hso-based modems for a couple of time so I'm pretty suprised that HSOConnect has graphical interface now

Try it instead of kppp.
