Olimex USB-NeoHub

The USB-NeoHub is USB hub which is both USB 1.1 and USB 2.0 compatible. This is important as the Neo6502 modern retro computer uses an RP2040 to interface USB keyboards and USB Flash drives.

The RP2040 USB interface is USB 1.1…and for some weird reason not all USB hubs on the market support this standard which leads to incompatibilities. If you attach USB keyboard to the Neo6502 it works, the same is if you directly attach a USB Flash drive. However if you attach USB keyboard through a generic USB hub there is a 50:50 chance that it may or may not work!

The problem with RP2040 host with some USB hubs is explained here. There is no known solution, so, to save customer frustration, Olimex decided to find USB hub chip set which guaranteed works with the Neo6502…and this is how USB-NeoHub was made!
