[AVR] reading keyboard via AT90USB1287

[banner]

Hi there
As stated in datasheet AT90USB1287 has OTG USB....but i can not understand from the datasheet that can I read a keyboard via this port or not?
Actually this link confuse me : https://blog.harrylau.com/2011/04/understanding-usb-otg-difference.html
is it Dual-role or peripheral only? ad if dual-role how can i understand which devices does it support?

thanks in advance,

it's a limited HOST USB OTG device, it can't do a lot of complicated stuff, but it can work with any USB keyboard (boot protocol or HID parse)

according the definitions on your link, the AT90USB1287 is a dual role device. By the same pins, it can work as a DEVICE, or as a HOST, and it has the negotiation capabilities of a true OTG device, but it isn't a complete HOST, it has some limitations... but it works for most stuff!!!

anyway if you don't have where to start, I want to recommend the Dean's LUFA, the examples worked with minimum modifications (I made my own board so I needed to choose the NO BOARD definition) it's said that you can integrate LUFA to Atmel Studio, but I didn't read more on the topic, you can also look for that stuff too...
