I want to build a Hid report descripotr with more than 300 bytes, and then i meet the the limite of 255 bytes.
I need to modify the driver to send the report.
Does someone has hints ?

This is not currently supported by the driver. You would have to define usbMsgLen as 16 bit variable and update all accesses accordingly.

I've reworked some of the driver code and while doing this made the size of usbMsgLen a configuration option.

If you want a developer snapshot of this version, please let me know by e-mail (support system for avr-usb). The new version supports several kB of transfer size.
