Hello.

I am working with AT89C5131.
I am developing device with HID keyboard functionality but not exactly keyboard.
I have used code in ATMEL website but speed was too slow for my application.
It seems to send a character per a routine cycle and send unnecessary 0. I tried to fix it but it didn't work. I don't know why.
I found sample code of generic USB HID device, and tried to convert it to HID keyboard. I tried change of descriptor by comparing USB monitor result with that of ready-made product.
But the number of descriptor was too big, especially hid report descriptor and sometimes my PC hanged.
I don't know how I can solve this situation and if there is sample code of HID keyboard with fast speed, I think I can solve this problem.
Does anybody know good site or reference of HID keyboard?
Please answer.

Thanks
