Unable to open device (access denied)

akiller commented 4 years ago

Hi,

I'm attempting to access my keyboard to configure the RGB lights etc using DuckyAPI that makes use of your library.

I have One2 TKL which is different model of keyboard to the one this project was targeted to but the same manufacturer. I've updated to the correct PID for my device and and am hoping they use the same protocol for all their devices.

When I try and open my device hid_read_timeout() in hid.c executes res = ReadFile(dev->device_handle, dev->read_buf, dev->input_report_length, &bytes_read, &dev->ol) which is returning 0. Checking GetLastError() returns 5 (ERROR_ACCESS_DENIED). I'm running in an elevated administrator process.

Just to confirm I'm getting this same result when I compile the master branch of hidapi directly, running entirely separate from the DuckyAPI project.

Hopefully you can point me in the right direction as this is far beyond my knowledge set!

This is the output from hidtest:

Sorry I must have missed this wasn't being maintained. Thanks I'll try that instead.
