Neat trick. I did not knew this.
For more information about genuine Vendor IDs, look here

My Kobo provides:
Code:
USB Vendor ID (in hex): 0x2237
0x2237 translates to 8759 (decimal) which according the above mentioned list belongs indeed to Kobo Inc.

That also applies to USB cables (E-markers) in which Vendor IDs regularly identify themselves as 0x0000 indicating they are not genuine. Using the list above you can see whether obtained USB cables are indeed "official" ones.
