Arduino on Mac; serial adapters not recognized.
Posted: 05 Jul 2020, 09:01
Hi all,
The Arduino IDE on my Mac OSX (High Sierra) has developed a problem in recognizing any usb to ttl adapters, the only one that will work is an UNO tricked into thinking it is an adapter by grounding the reset. The other one I have is a FTDI adapter that does not seem to register as a port (as it used to).
I have also tried to connect a NRF Nano via usb and again no port seems to be available for selection.
The RF Nano has a CH340 chip, and I found this https://github.com/adrianmihalko/ch340g ... s-x-driver , so I followed that and removed the driver first, then reinstalled it again. But it is still not recognized and available as a port for downloading.
I have deleted and reinstalled the Arduino IDE, rebooted the OSX, all to no avail. Strangely enough, when I check the hardware overview, the adapters do show up as a connected usb device.

I can get by with the UNO as adapter, or using usbasp for loading sketches, but I would like to be able to use the regular porting as well, so if there is anybody that can shed some light on this I would be grateful.
Cheers,
Max.

I did install the latest FTDI driver for OSX High Sierra from SilLabs, again without succes.bluejets wrote: ↑05 Jul 2020, 03:06May not be related but a couple of years back, ftdi pulled a nasty and re-wrote the drivers at least for windows which made the use of clone usb/ttl units useless.
It was done on the sneaky side in an auto update and the screams from all over forced the mob to re-instate the originals that would support the clones.
