 %description
-This package contains utilities for inspecting devices connected to a
-USB bus.
+USButils is a collection of tools that are designed to help users interact
+with USB devices on a Linux system. These tools provide a range of functions,
+including identifying and troubleshooting USB devices, monitoring USB traffic,
+and managing USB power.
+
+One of the key tools included in USButils is lsusb, which can be used
+to list all the USB devices that are currently connected to the system.
+This command provides detailed information about each device, including
+vendor and product IDs, device classes, and the driver that is being used.
+
+Another useful tool is usbhid-dump, which allows users to monitor USB
+traffic between devices and the host system. This tool can be used to
+debug USB communication issues and analyze data transmissions.
+
+USBdevfs is a virtual filesystem that provides users with the ability to
+interact with USB devices as if they were regular files. This tool can
+be used to read and write data to USB devices and can be used with Python,
+Perl, and other scripting languages.
+
+The usbreset command can be used to reset USB devices that are not responding
+or behaving abnormally. This command sends a USB-specific control message to
+the device, resetting it without requiring the user to physically disconnect
+and reconnect the device.
+
+Finally, the udevadm command is used to manage the udev device manager. This
+tool is responsible for detecting and configuring new hardware devices on the
+system and can be used to create custom udev rules for specific USB devices
+or modify existing rules.
+
+Overall, USButils is an essential set of tools for developers and system
+administrators who need to work with USB devices on a Linux system. These
+tools provide a range of functions that can help users identify, troubleshoot,
+and manage USB devices on their system.
