OK so I have finally purchased a cable tester and hopefully this will help me deal with the morass of "???" USB cables floating around my home. But… does anyone sell USB-capability stickers? 90% of these which don't have their own integrated badging are just going to be USB-2 cables of course but for the 10-20% which turn out to be 3.x, 4.x (20/40/80), or maybe even unbadged Thunderbolt of some stripe, I don't want to have to hand-write every one
