===== USB Subsystem =====

Actually, USB subsystem has no role.

==== Behavior ====

Micro USB device connector, is routed to Carberry microcontroller, and acts as CDC Emulation terminal.\\
In fact, if you connect Carberry USB to a PC (Windows or Linux hosted) you can talk with Carberry, using the same syntax used for Raspberry Pi UART.\\

==== Drivers ====

Depending by OS used, you may need or not to install specific USB drivers.

==== Linux ====

With Linux host, you don't need any drivers to talk with Carberry via USB.\\
Just plug Carberry into USB host, and look at the new device.

  ls /dev
  
And you have to see something like /dev/ttyUSB1

==== Windows ====

With Windows host, you have to install this specific driver to talk with Carberry via USB.\\
Download {{:carberry:usbdriver.rar|USB drivers}}, plug Carberry USB connector into host PC, and install drivers when requested\\.
In Device Manager in Control Panel, you will have a new //COMxx// port installed.
