quinton.smit@baesystems.com asks:
I am having difficulty in changing the report count to 64 bytes as this is the maximum size of the data packet sent over the usb from my host software. If I change the Report Count to 64 the usb still enumerates but does not send any data. Here is my code....Any suggestions?
