Has anyone got a HUAWEI E1820 working yet? This must be new because I can't find anything about it anywhere!

It doesn't work with any of the other HUAWEI configurations I've tried, so it probably has some new built in difficulty! The Windows software that came with the one I'm working on is called 'Tele2 Mobile Partner' but clearly made by HUAWEI.

I haven't managed to get any USB monitoring software to work on the windows machines I have at hand, but if I do and nobody else has already discovered the MessageContent, I'll post my results here.

I hope someone can help me here!

Why not just try the entry of the E1550 which looks identical to your's? It's in version 1.0.5 ...

I tried to use the usb_modeswitch (by hand) with the message given for the E1550 modem - to no avail.

The exact command given was:
usb_modeswitch -v 12d1 -p 14ac -W -M 55534243123456780000000000000011060000000000000000000000000000

One interesting thing I noticed is that the lsusb gave different readings (before running usb_modeswitch):
12d1:1446 at first
12d1:14ac after a short while (and then the USB disk got mounted)

I'm using Ubuntu 9.10.

Maybe you don't need to switch by hand.

The USB drive that is mounted could be a card slot in the device, and the device was switched all right, probably by the kernel.

If you try to switch the 0x14ac device you most likely treat the wrong part of the device.

You can try to bind the "option" driver to see if I'm right. Use trick with "new_id" as described in most of the recent threads in this forum.
