Hello,

First I have to say thank you for the usb_modeswitch module and support.
I have been tried few weeks, but it still doesn't work for Huawei E1750 3G dongle on mips embedded Linux.
The following log shows below seems translate to modem mode from storage mode succeed.

Code: Select all

Mode switch succeeded. Bye.

And then I using the pppd module and command "pppd file wcdma"
Sometimes it shows as:

Code: Select all

/usr/local/sbin # pppd file wcdma
timeout set to 12 seconds
expect (^M)

^BOOT:32136169,0,0,0,26^M
 -- got it

send (ABORT^M)
expect (NO CARRIER)
warning: read() on stdin returned 0

Connect script failed

And sometimes I get this:

Code: Select all

NO CARRIER
 -- failed
Failed (NO CARRIER)
Connect script failed

Can't get terminal parameters: Input/output error

It's really confused to me for few weeks, I not sure if I lost something important?
Thanks for your support!

I'm not sure whether I setup the usb_modeswitch module or pppd well?
And does the usb_modeswitch works correctly?
Thanks for your support again!

[Josh]

Hmm, are you using ttyUSB0 or ttyUSB2?

Your last pppd log says "ppp0 <--> /dev/ttyUSB2", whereas your option file says "/dev/ttyUSB0" ...

Which ttyUSB port did you use when you got that very first log where it said:

"^BOOT:32136169,0,0,0,26^M
-- got it"

??

Because that was most likely not the correct port to use.

With Huawei, port ttyUSB0 is usually the one for connecting.

Hi, Josh,

Thanks for your reply,
I think that I posted the wrong ppp-on script log, it should be ttyUSB2 for my testing result.
I have tried ttyUSB0, ttyUSB1 and ttyUSB2 for test because I'm not sure which port is the correct port.
(I know for Huawei model is usually using ttyUSB0)
How can I verify which port should be correct?

And I have trying to rebuild pppd module including rp-pppoe,
I using ttyUSB0 and ttyUSB2 for script ppp-on and ppp-on2 seperately.
(the ttyUSB1 didn't show correctly log so I think it's not the port should be)
the log shows as:
(I have tried ppp-on twice and ppp-on2 once as the log below)

and I modify the ppp-on-dialer script as:

Do you think the problem is due to my embedded system didn't recongize or connect correctly with my 3G dongle?
Thank you again!
