Possible Windows Rewrite of USB Product ID for Arduino Module
In this article, we will explore the possibility of rewriting the USB Product ID for an Arduino module on a Windows system. This process is also known as "spoofing" or "acting" as a recognized official mouse driver to read data output.
What is a USB Product ID?
A USB Product ID is a unique identifier assigned to a USB device. It is a 16-bit value that is used to identify the manufacturer and the specific product. The USB Product ID is used by the operating system to determine how to handle the device and what drivers to use.
Why Rewrite the USB Product ID?
Rewriting the USB Product ID can be useful in several situations. For example, it can be used to trick the operating system into thinking that a USB device is a different type of device. This can be useful when working with custom hardware or when trying to use a device with an operating system that does not have the appropriate drivers.
How to Rewrite the USB Product ID on Windows
Rewriting the USB Product ID on Windows can be done using various tools and techniques. One such tool is the "libusb" library, which allows developers to access and manipulate USB devices at a low level. Another option is to use the Windows Device Console (Devcon), which is a command-line tool that allows you to manage, disable, and enable devices on your system.
Using libusb
To use libusb to rewrite the USB Product ID, you will first need to download and install the library. Once you have installed libusb, you can use it to open a handle to the USB device and rewrite its Product ID using the following code:
#include <libusb-1.0/libusb.h>
int main() {
// Find the USB device
libusb\_device \*\*device;
libusb\_context \*context;
int r = libusb\_init(&context);
if (r < 0) return r;
// Find the USB device based on its Vendor ID and Product ID
r = libusb\_get\_device\_list(&context, &device);
if (r < 0) return r;
libusb\_device \*target\_device = NULL;
for (libusb\_device \*dev = device; dev; dev = dev->next) {
if (libusb\_get\_device\_vendor(&dev) == 0x1234 &&
libusb\_get\_device\_product(&dev) == 0x5678) {
target\_device = dev;
break;
}
}
if (!target\_device) {
libusb\_free\_device\_list(device, 1);
libusb\_exit(context);
return -ENODEV;
}
// Open the USB device
libusb\_device\_handle \*handle;
r = libusb\_open(target\_device, &handle);
if (r < 0) {
libusb\_free\_device\_list(device, 1);
libusb\_exit(context);
return r;
}
// Rewrite the USB Product ID
uint16\_t new\_product\_id = 0x9abc;
r = libusb\_control\_transfer(handle,
LIBUSB\_REQUEST\_TYPE\_CLASS & 0x40,
LIBUSB\_RECIPIENT\_INTERFACE,
LIBUSB\_CONTROL\_SET\_CONFIGURATION,
0, /* configuration value */
0, /* interface number */
(uint8\_t*) & new\_product\_id,
2, /* data length */
0, /* time-out */
0);
if (r < 0) {
// Error writing Product ID
libusb\_close(handle);
libusb\_free\_device\_list(device, 1);
libusb\_exit(context);
return r;
}
// Close the USB device
libusb\_close(handle);
libusb\_free\_device\_list(device, 1);
libusb\_exit(context);
}In this code, we first open a handle to the USB device using its Vendor ID and Product ID. We then use the libusb\_control\_transfer() function to rewrite the Product ID with the new value. Finally, we close the handle to the USB device.
Using Devcon
To use Devcon to rewrite the USB Product ID, you will first need to open a command prompt and navigate to the directory where Devcon is installed. Once you have opened a command prompt, you can use the following command to rewrite the Product ID:
devcon.exe update <device\_path> =product\_id 0x9abc
In this command, <device\_path> is the path to the USB device. You can find the device path by using the devcon.exe findall command to list all of the USB devices on your system.
In this article, we have explored the possibility of rewriting the USB Product ID for an Arduino module on a Windows system. We have discussed what a USB Product ID is, why you might want to rewrite it, and how to do it using libusb and Devcon. By following the steps outlined in this article, you can spoof a recognized official mouse driver and read data output from your Arduino module on a Windows system.
