FDTI only one of seven devices are showing up as an output.

[ping-mee]

I run OLA on a Raspberry Pi 4. I have connected seven FDTI interfaces to it (3 directly via USB and 4 over a USB hub). They all show up in /dev/.

Please can we have the olad -l 4 logs @ping-mee :
https://www.openlighting.org/ola/get-help/ola-faq/#How_do_I_get_olad_-l_4_logs

I suspect it might be down to a lack of unique serial numbers off the top of my head.

@peternewman you were right

How can fix this? Can I change the serial numbers or just give them aliases?

[peternewman]

It looks like you may be able to do it with FT Prog:

However if they've all got the same serial number they're probably cloned rather than genuine FTDI chips so I don't know if the tool will still work with them or it might even try and brick them!

@peternewman So I tried using FT Prog, but because these chips are emulators of the real FTDI chips, it doesnt work. I saw that the OpenDMX module uses the /dev/ path instead of a serial number. Is it possible to use more then 3 devices in the module?
