+# USB
+
+Neat and simple example of how the digispark can become a USB device and react to interrupts. Heavily based on http://codeandlife.com/2012/01/29/avr-attiny-usb-tutorial-part-3/
+
+## Usage
+
+Build the program and flash it as usual to the digispark.
+
+```bash
+$ make clean && make
+$ micronucleus usb.hex
+```
+
+After the program loads, you should see a new USB device:
+
+```bash
+$ lsusb
+Bus 111 Device 222: ID 16c0:05dc Van Ooijen Technische Informatica shared ID for use with libusb
+```
+
+You can now flip the LED by calling the test program, requires root privilege or proper udev rules:
+
+```bash
+$ ./usbtest on
+$ ./usbtest off
+```
