Huawei e398 3G Stick

[ScottVega]

Hi Everyone For the last 6 hours I' ve been trying to get a Huawei e398 3G Stick to work with my FortiGate 100a 4.0 MR3 Patch11. Even though, the stick is listed in the list of compatible devices, it isn' t recognized until i manually add it according to this thread: https://forum.fortinet.com/FindPost/76983 Unfortunately this didn' t help. now the modem seems to be detected:

 FG100A2104400486 # diag sys modem external-modem
 External modem vendor: Huawei
 External modem model : E398
 

but when i start the diag command, I get this:

 FG100A2104400486 # diag deb en
 
 FG100A2104400486 # diag deb app modemd
 modemd debug level is 255 (0xff)
 
 FG100A2104400486 # exe mod dial
 
 FG100A2104400486 # redails:0 isp:0 dev:/dev/ttyusb0 tel:*99#
 mode=0, dial=2, autodial=1
 modem state changed: 5(hw_err) -> 0(uninit)
 modem state changed: 0(uninit) -> 1(inactive)
 modem: Launch modem due to manual dial.
 modem: unable to open modem device - check hardware.
 modem state changed: 1(inactive) -> 5(hw_err)
 scan_usb_dev():597

Then I tried to install it on my computer. there it works just fine. so i guess it must have something to do with my configuration... here' s the config:

 FG100A2104400486 (modem) # sh
 config system modem
 set status enable
 set pin-init " at+cpin=7216" 
 set auto-dial enable
 set phone1 " *99#" 
 set username1 " none" 
 set passwd1 ENC k0Qwbf15hb+HSIVhhPZEQCOB9VOFmOuEbHCfZ0S7pQi+Dza/o9zm30HLrlBs0XNJUFwiOgTJNeGc8FW/bwxuu9mENMqPEKxQz3zKVZcSDDlO6jmU
 set extra-init1 " at+cgdcont=1,\" ip\" ,\" gprs.swisscom.ch\" " 
 end
 
 FG100A2104400486 (modem) #
 
 FG100A2104400486 # conf sys 3g-modem custom
 
 FG100A2104400486 (custom) # sh
 config system 3g-modem custom

I hope you can show me a way to get that thing working... cheers ScottVega

Google search says there is " something" out there, but nothing from the official manufacturer' s website. If this was Windows, I' d would check the hardware device ID (VEN & DEC) codes then google search for alternate/rebranded names the chipset/device may be known under.

Hi Dave Hall Hi Selective So I' ve been doing a lot of googleing but as far as i can tell, i already got the latest firmware. it seems like fortigate is using a linux tool called usb_modeswitch. on the developper page i found a windows tool to capture the communication between the stick and windows xp. unfortunately the output is way too much to post here (about 23 Megs). the other thing is, that i simply don' t know how to get the message string out of the dump. i' ve found some strings that seem to have the same form as the ones mentioned before. on this site it is explained how to find that string, but it seems that i am unable to perform this task as it is way out of my league of troubleshooting. another thing i got is this, after trying different strings, maybe this is helpful as well:

 #diag deb application modemd 255
 
 # diag deb en
 
 # scan_usb_dev():597
 scan_usb_dev():597
 scan_usb_dev():597
 scan_usb_dev():597
 scan_usb_dev():612
 got one: 12d1:1505:08
 _usb_detach_driver(' usb-storage' )
 act_msg(): ep=1, len=31
 scan_usb_dev():597
 scan_usb_dev():612
 scan_usb_dev():597
 scan_usb_dev():612
 got one: 12d1:150a:ff
 act_msg(): ep=1, len=31
 _usb_bulk_write(1) failed: could not get bound driver: No data available
 

i will edit this post, as soon as i uploaded the dump file. thank you for your help! Here' s the link to the file: USB Snoop.zip

Hi Everyone I thought i check if there is any progress on this topic... but it seems like i' m out of luck with my 3g stick. does anyone have suggestions on how to get to that correct init string so the right driver will be loaded? thanks for your help cheers ScottVega
