Περιγραφή:
The Discover your hardware docs say that the canonical model name of USB devices is determined by the "idProduct" field of lsusb's output. For at least one USB device (17e9:02ee DisplayLink VGA Display Adapter), that field is the empty string (tested on PureOS Byzantium), which presumably makes such advice suboptimal. lsusb seems to use the "iProduct" field as a fallback when displaying the device name in such cases. Is that fallback policy acceptable for h-node? (I'm happy to edit the wiki accordingly, but wanted to ask for feedback here before I make such a change unilaterally.)
