I did attempt the solution provided by darBis, but it didn't manage to get the PC to recognize it either.ДЄctive Oldest Votes.

In source files you have pointed out, there is everywhere sub class set to 0x You can try to find detailed information about usb descriptors at USB. I might be mistaken, but if you want your devide to be recognized during boot, it's bInterfaceSubClass should be 0x01 Boot device subclass. I have started using Teensy which is Arduino compatibleand it works pretty well. Arduino does not support the boot protocol.

The modifications I've made haven't helped, and I suspect it is because the Leonardo is a composite device which exposes the serial communication, keyboard emulation, and mouse emulation on the same USB port. I have been making modifications to the USB device descriptor of the Leonardo, trying to make it match a Dell L as much as possible. It is recognized as a generic HID keyboard and will type an 'A' every five seconds.

Now this example works great on my Windows XP machine. I have been playing with the Leonardo and wrote a very simple sketch based off the Blink example. I am trying to use an Arduino Leonardo for keyboard emulation since that is one of its advertised features.

You add a crystal, a few capacitors and that's it. These contain a built-in standard-compliant USB interface and a built-in 3.3V LDO to power it. A think there is also an ATmega8 or 16 U-something, very similar to AT90USB162. However, a slightly cheaper variant exists: AT90USB162. Quote from: magic on May 02, 2020, 06:48:05 am For production, that will be a lot of waste keyboards to dispose of As for USB on ATtiny85, the problem was that Atmel wants you to run the micro at 5V for more than 8MHz or so but USB 1.1 signals are 3.3V, which means: - the outputs of the micro ought to be clamped to 3.3V with zeners or buffered by a suitable logic chip - the inputs to the micro may not reach the guaranteed Vih threshold unless they are shifted to 5V by a suitable logic glue chip In practice, however: - USB ports are mandated to withstand 5V continuously for 24 hours on any pin - 3.3V will generally register just fine as high on CMOS running at 5V - I have overclocked a few AVRs to 30~40MHz and even there, 5V or 3.3V made little difference - YMMV ATmega32U4 is not a cheap solution.
