Huawei E1550 3G Modem

This page (http://live.gnome.org/NetworkManager/MobileBroadband) mentions to report all non-working "out of the box" modems to the vendor as a kernel bug so I'm doing that.

It does work you just have to use the usb_modeswitch workaround.

It should just work out of the box and be detected as a 3G modem for NetworkManager's use.

Comment 3 Pete Zaitcev 2010-03-10 00:18:39 UTC 
Thanks. I see this is 0x1446, which is beyond even what 2.6.33 includes into
the initializer list in unusual_devs.h. So, what do we do?

I am not the kernel maintainer, but I think we should add 0x1446 to F12
just to tide Jonathan over. Then, make sure that usb_modeswitch (maintained
by Huzaifa now) is well integraded with NetworkManager in F13 (Dan Williams,
right?) and so it works there. This may need cloning this bug or filing
a new one, against NM component.

BTW, I notified Dan about the obsolete language at live.gnome.org
and he said he would fix it.
Comment 4 Jonathan Pritchard 2010-03-10 10:47:28 UTC 
Thanks for jumping on this.

It's great that the E1550 works but like you say, I'm sure there's some way we can automate this usb_modeswitch. Which makes it pretend to be "Bus 001 Device 004: ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem" in lsusb.
Comment 5 Jonathan Pritchard 2010-05-15 15:38:51 UTC 
Using the newest non-stable NetworkManager packages and the newly released usb_modeswitch 1.1 everything is detected and configured automatically it appears. This is perhaps a result of my previously entered usb_modeswitch settings but it's all fluid, works out of the box now. I presume this will be the same for all users in Fedora 13.

Thank you to whomever got this magic to work.
