+# G-Wolves HTX driver
+
+G-Wolves USB Vendor ID: 0x33e4
+
+Product IDs:
+- G-Wolves HTX 4K Wired: 0x5708
+- G-Wolves HTX 4K Wireless: 0x5707
+
+## Features
+
+The device works using USB HID feature reports.
+
+The device uses only one feature report (report 0).
+The SET_REPORT command can be used, setting a command byte to the desired command,
+to get an output (for example, you set report with COMMAND_DPI_SETTINGS, and
+then get report to obtain a DPI_SETTINGS_REPORT structure).
