Libusbwin64develfilter1260exe New -

Once installed, you can write a simple C program to communicate with a USB device. Here is a minimal example that finds a device by Vendor ID (VID) and Product ID (PID) and prints its descriptor.

#include <stdio.h>
#include <libusb-1.0/libusb.h>
int main() 
libusb_device **devs;
libusb_context *ctx = NULL;
int r;
ssize_t cnt;
r = libusb_init(&ctx);
if (r < 0) return 1;
cnt = libusb_get_device_list(ctx, &devs);
if (cnt < 0) 
    libusb_exit(ctx);
    return 1;
for (ssize_t i = 0; i < cnt; i++) 
    struct libusb_device_descriptor desc;
    r = libusb_get_device_descriptor(devs[i], &desc);
    if (r < 0) continue;
    printf("VID: %04x, PID: %04x\n", desc.idVendor, desc.idProduct);
libusb_free_device_list(devs, 1);
libusb_exit(ctx);
return 0;

Compile with:

gcc -o usb_list usb_list.c -lusb-1.0

This works because the filter driver installed by libusbwin64develfilter1260exe new exposes the device to libusb’s user-space API.

Official libusb for Windows is distributed as: libusbwin64develfilter1260exe new

Notice that no official release uses the exact string libusbwin64develfilter1260exe. The format is odd:

This suggests the file may be a typo, a renamed executable, or malware disguised as a libusb tool. Once installed, you can write a simple C

The addition of the word new is a red flag in the open-source world. Why? Because the official libusb-win64 project has not had a release named "new". The last official binary release for Windows was v1.2.6.0 (hence 1260) from 2012, or later versions like v1.2.7.3 from the libusb/libusb GitHub repository using the libusbK driver stack.
