incorrect class name

[zakaria-chahboun]

Hi guys! I want to get a list of usb devices, Then catch my usb printer by it class
So i did this

package main

import (
	"fmt"

	"github.com/gotmc/libusb/v2"
)

func main(){
 
 	c, err := libusb.NewContext();
 	if err != nil {
 		panic(err)
 	}
 	
 	list, _:= c.DeviceList();

 	for _, device := range list {
 		d,_ := device.DeviceDescriptor()
 		fmt.Println(d.DeviceClass)
 	}
    
}

output:

Hub class.
Hub class.
Wireless class.
Each interface specifies its own class information and all interfaces operate independently.

its gives me Each interface specifies its own class information and all interfaces operate independently. instead of "printer" class!

in terminal i get:

❯ lsusb --verbose | grep "Printer"
  iManufacturer           1 Printer-58
      bInterfaceClass         7 Printer
      bInterfaceSubClass      1 Printer

Why? and Thanks!
