mbed keyboard I/O

Hi guys,

I was wondering if there were any libraries that allowed for keyboard in and out on the MBED. I've found libraries that do either/or and one that does keyboard with serial, but haven't found any others. The issue that I'm running into is that I need the MBED to show up as a keyboard on the output side and as a host on the input side. Hopefully that makes sense. I was also wondering if that's even possible through a single USB interface.

Thanks, Ankit

Regardless if it would be possible on the mbed (highly unlikely), then you would need to have two USB hosts on a single bus, that isn't supposed to be the case. You really need two seperate busses.

I figured that would be the case. I think I will just use a SPI-based USB peripheral chip to receive keyboard data. That should save me the trouble of cracking my skull open over this project. Thanks for the help Erik.
