At the moment i have two devices connected to the iMito MX1. These are:
Behringer U-Control UCA222 USB Audio Interface
I can wholeheartedly recommend this device to those looking for a external soundcard to use with their iMito. Sure, its almost half the price of the stick itself but has great features such as optical out and other connectivity options. Good, clear sound, headphone input with volume knob and according to some also works similarly to a cheap USB Dac although i havent really noticed any benefits in the audio on that level myself.
Also using the Logitech K400 mentioned in this thread earlier. That too a sweet piece of hardware. Both periphals worked right out of the box.
I have tried to get my Huawei E353 3g modem (Hilink) working. No success so far. Does the Imito even have support for external 3g? If so what might i be doing wrong? Only tried it connected to the different ports but it doesnt get detected.
Overall... Very happy with this device.
