Send command to USB device (FingerPrint Scanner) with no driver for Linux
Sending commands to a USB device like a fingerprint scanner with no Linux driver can be challenging and may not always be possible. However, you can try using the `usbhid-dump` tool to interact with the device at a low level and send raw USB HID (Human Interface Device) reports to it. Please note that this approach may not work for all USB devices, and you might need some information about the device's HID report structure. Here are the general steps to attempt communication with a USB device using `usbhid-dump`: 1. **Install `usbhid-dump`:** You can install the `usbhid-dump` utility on your Linux system if it's not already installed. Use your package manager to install it, or you can compile it from source. 2. **Identify the Device:** To communicate with the USB device, you need to know its vendor and product IDs. You can use the `lsusb` command to list all connected USB devices and find the appropriate entry for your fingerprint scanner. Note down the vendor and product IDs.
