Hi,
I tried to use the example code from
http://avrusb.wikidot.com/driver-api to "Sending data to the device". My Problem is, that i cannot compile the project. "VENDOR_RQ_WRITE_BUFFER" was not found.
i always get an error
../myUSBdev.c:27: error: 'VENDOR_RQ_WRITE_BUFFER' undeclared (first use in this function)
whats my failure?

This is example code only. When you write your own device, host and device must agree on numerical values for the requests. This define must be shared between host software and device so that both use the same numerical value.
