USB hub with LED?
i already have a usb hub, but i want to make mine so that a LED light turns on when u plug something into one of the hubs port. Mu hub has 4 ports, so i would have 4 lights. If this is too confusing, then think of it this way: if i put something into port 1, the light above port 1 should turn on. thanks in advance
Probably would not be worth the effort. I bought mine for a little over $20 and it has the LED’s built in. You would need room to open the unit and mount the chip and the wiring.
