And a tip, you also need firmware
gobi-loader
gobi-firmware

Make the qcserial module to the kernel.

Okay. Here we are:

lsusb:
Code: [Select]
Bus 002 Device 002: ID 03f0:201d Hewlett-Packard un2400 Gobi Wireless Modem (QDL mode)

dmesg:
Code: [Select]
usbserial: USB Serial support registered for Qualcomm USB modem
qcserial 2-5:1.0: Qualcomm USB modem converter detected
usb 2-5: Qualcomm USB modem converter now attached to ttyUSB0

QDL mode means that modem now ready to get flash firmware.  Gobi Wireless Modem has no it's own firmware, and need to be loaded each time as modem power on. There is gobi_loader utility which load firmware files amss.mbn, apps.mbn and UQCN.mbn.

So i have got it all from https://wiki.archlinux.org/index.php/Gobi_Broadband_Modems. gobi_loader was successfully Compiled. I Flashed modem by

Code: [Select]
/lib/udev/gobi_loader /dev/ttyUSB0 /lib/firmware/gobi/
rmmod qcserial
modprobe qcserial


but nothing have happened. Theoretically after flashing additional ttyUSB* has to appear. But no. I still have only
lsusb:
Code: [Select]
Bus 002 Device 002: ID 03f0:201d Hewlett-Packard un2400 Gobi Wireless Modem (QDL mode)

dmesg:
Code: [Select]
usbserial: USB Serial support registered for Qualcomm USB modem
qcserial 2-5:1.0: Qualcomm USB modem converter detected
usb 2-5: Qualcomm USB modem converter now attached to ttyUSB0

Any suggestions?

I am blind idiot, trying load Gobi2000 firmware to Gobi1000 device. Now it's OK. Two ttyUSB* devices has appeared and connecting via "microcom".
Code: [Select]
ATI

Manufacturer: QUALCOMM INCORPORATED

Revision: D1020-SUUAASGA-4352  1  [Apr 14 2008 19:00:00]
IMEI: 980049004712890
