I am trying to decry all the usb connected to my pc using pyusb, but I have the following problems:
1.- you can not find all the devices (there is no hdd connected at the moment of execution)
2.- How can I get the iInterface (to detect the name of the device) try:
for cfg in dev:
print(cfg[0]['iInterface'])
here is the complete code
import sys
import usb.core
import usb.util
dev = usb.core.find(find_all=True)
for cfg in dev:
sys.stdout.write('hex VendedorID='+hex(cfg.idVendor)+'& ProductId'+hex(cfg.idProduct)+'\n')
print(cfg)
And this is what it returns:
