Reading from a Vendor Defined HID device

Danny Wong

Hi,

I have a vendor defined hid device with Usage Page: 0xFF00 and Usage: 0x01. I can read it through CreateFile, ReadFile function on Windows XP. However, the data rate (500 msec after 2 packets received) is far lower than the MCU transmission rate (15-byte/packet in 5ms).

Could anyone give me a hint on this situation? Thanks a lot !!!!

Danny
