Disappearing Modem on USB port

[PJJ]

Still working on getting the U600 Franklin Wimax modem to work. I believe I have not been able to flip the USB stick into modem mode, though I have seen a device "sg0, type5" mentioned after the storasge section is shown.

The modem somehow appears to be around. Look at this dmesg printout:

sudo dmesg|grep -i ttyUSB
[ 29.497757] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[ 29.498090] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB1
[ 29.500987] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB2
[ 191.857639] option1 ttyUSB0: option_instat_callback: error -108
[ 191.857872] option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0
[ 191.859622] option1 ttyUSB1: GSM modem (1-port) converter now disconnected from ttyUSB1
[ 191.860575] option1 ttyUSB2: GSM modem (1-port) converter now disconnected from ttyUSB2

May question now is: Why does it get disconnected before I can do anything?
Cannot even get to KPP to attempt a connection.

According to Sprint it is necesary to first get the 3G modem to work before the 4G part can be installed. There is a driver for the 4G modem in the staging drivers section.
It is said to work. I got it installed together with a GUI and the wimax daemon is running. But still no modem to connect to.
See above!

Any ideas that could put me on the right path?

I'm curious what the output of dmesg | tail shows. Unplug the modem for a little while and then plug it in and try dmesg.

Thanks for the reply. I do not klnow what happened but today I get this:
Here it is. Note that I had to use the 'option' driver to get this:

1.957773] usb 1-2.2: New USB device found, idVendor=1fac, idProduct=0150

And with the 'option' serial added:

lsusb shows trhe unchanged USB stick:
Bus 001 Device 009: ID 1fac:0150

Doing the dmesg command with the actual modem product number (0151) results in identical responses. This modem just does not want to flip. I beginning to wonder whether something in my laptop setup might prevent it.

The more I try, the more confused I am getting. Obviously.

What happens? I have something going on with KPPP here. It will only run when launched through a Konsole/Terminal. Runs fine that way.

I've had Modem-Manager work for a while and then quit working at all. No idea why, so I use Konsole to launch KPPP. Which works absolutely fine.

I have a solution to the vexing problem of how to get the Franklin U600 modem to work on Kubuntu 12.10. A detailed report on what I did and who helped me to get there will follow soon.
