USB_ModeSwitch

Posted: **26 Jan 2013, 05:36**

This device manual says it works as a USB modem, but no word for Linux.

This is a link to the product, but it is in spanish:
http://www.huaweidevice.com.ar/celulare ... s/60-u2800

I connected it to my Ubuntu 12.10 laptop and nothing happens.
If I connect an Android 4+ instead and use USB tethering, Ubuntu recognizes a wired internet connection and in fractions of a second I can be enjoying the Internet.

Has anybody tested this phone?

Can somebody help me, Im not a tech guy, I could then post a guide for other people.

Thanks,

Post the output of "lsusb -v" when the phone is connected to the laptop, and we can start from there.

Your listing above only shows the TF/SD card in your phone and no modem.

From the manual:

"How to use the U2800 as modem to access the internet?
To use it as a USB modem, you need operate your phone
1. Phone setting: Main menu－＞Settings－＞Connectivity－＞Network Access Point "

If you didn't do that, then do it and show the new lsusb listing for the Huawei device.

Also, run "lsusb" in a root shell or with 'sudo' to get rid of the errors you are seeing.

Posting the output as text is fine. If you use the "

Code: Select all

" tag, the output will be nicely formatted.

We are still seeing the storage mode, though. Is there any setting to change the USB connection mode on the device?

There is no option on the menu for USB connection mode, I was looking for that from the beginning, I looked for it again and googled it but found nothing.
Being a chinese phone, its manual is terrible, it says when you connect to the PC it installs "PC suite" on the PC, I think they assume everyone has Windows so they don't mention any OS.
My Ubuntu 12.10 does not recognize a USB storage device either, in other words, nothing shows when I connect the phone.
Maybe that "PC suite" handles the communication ???
Should I test it in Windows? should it change the mode permanently?
Thanks,

Revisiting this topic after quite a while ...

If Prada is still listening:

Put the attached file on your Ubuntu system. Plug the phone in and wait a moment.

Run this command as root or with "sudo":

Code: Select all

# usb_modeswitch -I -v 12d1 -p 1805 -c 12d1.1805.txt

Any changes afterwards?

Hi Josh
"Put the attached file on your Ubuntu system": does it mean copy the file to the home folder?

I did it and below is what I got, but nothing happened, no usb drive detected and no option to tether, of course

I did not specify the target folder because it does not matter where the file is as long as you are in the same folder when running the indicated command.

Two more configuration variants to try below ...

Hi Josh, what should I expect after doing these steps?

Posted: **30 May 2013, 11:23**

If the phone is behaving like Huawei modem sticks, the USB ID should change and/or the detailed "lsusb" output should be very different from the one you posted.

This is just a guess though. There may be a different mode switch 'command' for this phone which can only be found by 'sniffing' the driver<-->phone communication on Windows.

Posted: **30 May 2013, 23:23**

I got it working.

Upon use Ubuntu 13.04 adds two /dev/ttyUSB? devices.

Both devices respond to AT commands.
