Our goal

to create USB host device with

microcontroller ATmega2560

to create a device that benefits from all

ATmega2560 features

to create a device with SL811 USB

controller

to create a device for universal purposes

e.g. for WiFi connection, BlueTooth….

USB Stack

API similiar to libusb

(http://libusb.sourceforge.net/)

Support

– reading device, configuration, interface, endpoint and string descriptors – Control, Bulk, Interrupt transfer r/w

Isochronous transfers and timeouts are

not implemented yet
