USB peripheral connection

Question

It seems that UsbManager has gone to assembly. How do we deal with usb peripherals now?

Things like usb-> serial etc. using https://github.com/mik3y/usb-serial-for-android

Answer 1

Currently, the HAL peripheral system does not recognize usberial based UART peripherals.

But if your USB device (for example: Arduino) provides separate UART TX RX contacts, you can contact it using the UART Peripheral API .

Protest:

• Remember to cross TX and RX when connecting peripherals to the UART board of your development board
• On the Raspberry Pi 3, the console must be disabled, see UART peripherals on Android Things for Raspberry Pi 3

Answer 2

In a known part of the article , it is noted that USB support is disabled in the developer preview.

However, I did a quick test on Pi3 and high-end peripherals such as a keyboard, and sent the correct events to the application. Only low-level access is disabled.

Answer 3

As @devunwired commented on in the Google IoT Developer Community : USB accessory support is not currently enabled - preview RC1.
