【HELP！！！】libusb_control_transfer returns -1

[Sleepingbug]

1，test environment：
windows 10 x64, libusb win32, visual studio 2017
lib-1.0.23

2，issue:
libusb_control_transfer returns -1.
I use a tool named Bus Hound to send the same data to my usb device, my device can receive the data and the data can be captured by Bus Hound.

@Sleepingbug Did you solve it? i have a same question. thanks

Try using HIDAPI and not libusb for HID device.
https://github.com/libusb/hidapi

[mcuee]

Also please read HID specifications here.

You have to know the communication protocol of the device. If not, no one can help you,

sorry, my english is poor。
first step:
i use bus hound to send a report like this:(this works)

then, second step:
i want use libusb or hidapi(Recommended by you) to send the same data to hid device。
but libusb_control_transfer(libusb) or hid_write(hidapi) getlasterror() return 1 (invalid function).
