Libusbwin64develfilter1260exe New Link

The word "new" is ambiguous. It could mean:

Important: Because new is not standard, exercise caution. We will discuss security later in this article.

No single authoritative project uses this exact name widely; it is likely a packaged or vendor-specific installer that installs a libusb-based filter driver or helper for 64-bit Windows systems.

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. libusbwin64develfilter1260exe new

#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.

If you specifically need the legacy filter driver: The word "new" is ambiguous

Developers and hobbyists seek out libusbwin64develfilter1260exe new for the following scenarios:

Tools like dfu-util (Device Firmware Upgrade) require libusb to communicate with USB bootloaders. Important: Because new is not standard, exercise caution
