Status

The C290 can report 2 seperate USB device ID's. The mode the phone is in can be toggled with the moto4lin application. In either mode, I'm not yet able to see any data on the phone.

Vendor and Device ID

This phone changes it's device ID depending on the mode it is in. You can use moto4lin to change the mode between P2K & AT.

AT mode:  Bus 003 Device 014: ID 22b8:2ac2 Motorola PCS
P2K mode: Bus 003 Device 011: ID 22b8:2a21 Motorola PCS

Results with minicom

You can send AT commands to this phone if you use the device /dev/ttyACM0

This only seems to work when the phone is reporting it's device ID to be 2ac2. The phone will autodetect the speed you are trying to talk to it at. I tried 9600 and 38400 and they both worked.

OK

It looks like this switches the phone to device ID 2a21. At that point, AT commands don't seem to work anymore.

Normal output from powering on the phone while it's connected to the USB cable:
