I'm pretty new to microcontrollers and Arduino and since I can't find any satisfying information on my problem, I hope that you might answer them:
My project is actually quite simple: I just want to write out data over a serial connection via USB, the problem: My Arduino Nano has to run as USB Host. That's because the other device is a vacuum cleaner: Neato XV-25 with a mini usb jack. I was already able to 'talk' to it using a Raspberry Pi.
Since I don't have much knowledge about USB communication, I would like to know the following, before I start digging deeper:
I found out, that I would not be able to use the 'usual' usb port of the nano. But I've read a few things about that 'V-USB' library, but did not understand very much. Would it be possible to create a USB Host with this library, that can communicate via a virtual serial connection?
I stumbled across the USBHost for Android Nano. It's a shield, but I'm not sure if it would fit my needs. Is it able to handle serial communication? And is there somewhere a store where I can get it cheap? I think more than 20$ for a shield is a bit too much...
