Doc question

[jens breitenstein]

Hi LUFA users!

I am new to this topic but wonder about the docs, maybe you can help me.
Under "Supported Third Party Boards" I can see PJRC Teensy (1.x and 2.x versions).

Unfortunately Teensy 2.0++ makes use of an AT90USB1286 processor.
According to "Supported Microcontroller Models" AT90USB1286 is not listed as supported model for USB-Host-Devices, but AT90USB647 is, which Teensy does not use.

Same applies to ATMEGA32U4 aka Arduino Pro Micro which also lacks USB-Host support. AT90USBKEY is discontinued and AT90USBKey 2 is very expensive, can buy 2 Raspberry's instead.

Can anyone tell me a development board having a processor model with LUFA-USB-Host support?

Thanks in advance 

Jens

The 8-bit USB AVRs are a bit long in the tooth now, and I don't think the host-mode supporting chips ever had much traction.

The last I heard (years ago) was that Atmel stopped production of the AT90USB647 chips in favour of only producing AT90USB1287 chips for applications that needed the host mode, but I haven't seen any development boards using the latter for a long while now.

In general, people are migrating towards more powerful ARM chips if they need USB host mode, as the extra RAM/CPU power is useful in such applications where USB hosting is desirable.
