I need to develop a USB HID project using LPCOpen/LPCXpresso and LPC4357. Starting from the example "usbd_rom_hid_generic", I slightly modified it to send 8 bytes to PC and to receive 64bytes (from the PC).

To speed up the USB communication, I changed the HID descriptors in this way and I improved the speed to a "decent level":
WBVAL(0x0040),//WBVAL(0x0004),/* wMaxPacketSize */
0x02,//0x20,/* 16ms */          /* bInterval */  //--++

Unfortunately I'm not an USB expert so, I'd like to have some suggestions to further improve the HID speed.
