Problem with HID USB (PIC18F4550 and EasyHID)

easyhid

Hi everybody!
I have a problem when use EasyHID software to receive data from USB HID device. EasyHID generates a mcHID.dll file, a Visual C++ 6.0 project automatically. Read from and Write to USB HID device are the same as read and write to mcHID.dll file.
But problem occur when I transmit from USB HID device. Firmware which I use is ex_usb_hid.c, an example in CCS software (PIC 18F4550). When I transmit a large file (> 10MB) my PC program cannot receive all of data. But when I use USB monitor (HHD software) to manage data transfer over USB HID device, I see all of data, they've transmitted from USB device to computer.
(I use a count variable to count bytes transmitted from USB HID device. My firmware transmit N bytes but VC++ program received only N-m bytes, m is not stable)
I cannot fix this bug, please help me, please show me incorrect points.
Thank you very much!!!

Ok, the problem is with EasyHID. The host software could not handle that traffic. No one here wrote that EasyHID, so you should ask the author(s) of EasyHID for a solution. Or you could dig in the C code has been created by EasyHID and improve it.
