    Question how can I increase the size of HID usb buffer?

    hello everybody,

    I would increase the maximum buffer size of my hid usb device (18F2550)
    I used easyhid to write a little exemple

    I can increase the size to 64 (input or output) but not more
    I would a 128 buffer size input/output

    How can I do it if it's possible?

    thanks

    Send 2 reports of 64 bytes.

    HID is limited to 64 byte reports. You cannot increase it.
