I'm using the freescale USB stack - hid keyboard  in one of our project(using MKL25). during the test , the reporting rate is some slow,  can only achieve about 100 keys /second. when we try to report faster, some keys will lost. so is there a way to speed up the reporting rate, say, to make it report about 300 ~500 keys/second. is it possible? according to USB2.0 spec, the reporting rate should be 1000Hz, but during our test, the FSL usb stack can only be about 60Hz. how to improve it?

thanks a lot
