Sorry I did'nt see your post before. I was looking after the new Raspberry B+ to see if any body have post some news about usb_modswitch so I have see your post just now. With Raspberry A and B (first generation) there is a bug with the USB controller used in the Broadcom BCM2835. So I think nobody ...

For the power I have plug the E220, and before the E173S, to a powered usb switch with a 5V 3A power unit. As it works well when it is connected to a computer running Windows with the same powered usb switch, power issue should not be involved here. To be sure I have to make some test under debian a...

Hello Josh, thanks for the informations about huawei E220. I have done a lot of test with the Huawei E220, it's working perfectly with rasberry and raspbian. About 100 hardreboot (taking off the powercord), and 100 times the modem huawei E220 come up ;-) Tested on raspberry A and B with and without ...

Hello,

test done with raspberry model A, same behaviour.
It seems to be more often modem on, but I'm not sure of this, just a feeling

So I will probably use an usb 3G dongle like the Huawei E220, normally this dongle don't need to use usb_modeswitch.

Bests Regards,

Hello, Raspberry Pi has USB port problems (google it ) and that is likely the reason for the misbehaviour that you see. Erff this should mean it will be the same for all 3G dongle using the "ZeroCD (TM)" feature. I will "google it", and if there is no solution I will see if I can...

Hello, I have probably the same problem. I have a E173s 3G USB dongle (from Tmobile), on a raspberry with raspbian. When I start the raspberry sometime the E173S is in modem on, some time in modem off. When modem is off, dsmsg give : [ 0.000000] Console: colour dummy device 80x30 [ 0.000000] console...
