Hello!

usb_modeswitch 2.2.0 doesn't work with my Huawei e1750 3g modem. Connection log is:

How to fix it?

[Josh]

Your problem is here:

Code: Select all

Driver detach failed (error -5).

It's an I/O error (whatever that means ...). Maybe there is a problem with the usb-storage driver.

One thing you can do is to play around with the "use delay" of the storage driver. There is a convenience facility in /etc/usb_modeswitch.conf to change the value.
Note that any changed setting will only be active for the second plug-in of the modem after the change.

[vzotov]

Some driver problems. Changed OS from FreePBX to Ubuntu Server and it worked! Thank you!

[vzotov]

Unfortunately there is another problem. I have now ubuntu server 14.04 i386 (usb-modeswitch v2.1.1) and my e1750 doesn't work properly:(

So, when I try to call from asterisk I have error:

Looks like the modem has resetted to an undefined state.

Are you on an embedded platform?
Make sure the modem gets enough power. Wireless modems need juice!

I have an Intel NUC system which has problems delivering a stable current to my Huawei E398. Using an independently powered USB hub helps.

[vzotov]

Thank you for reply!

I try to connect my 3g modem via powered usb-hub and now usb_modeswitch doesn't see e1750 at all (log when I connect E1750):

I run Asus notebook with ubuntu server 14.04 i386 installed by myself.

[Josh]

That is even stranger than before ...

The good thing is that the Huawei is in modem mode, so the mode switching has succeeded. However, the hub should never have triggered a usb_modeswitch run.

Have you altered the "rules" file of usb_modeswitch in any way?

What does "dmesg" show, right after the plug-in?

This is completely bogus. One interface, two drivers ...

Please post the output of "lsusb -v -d 12d1:1001" so that we can see the exact USB setup of the device.
