Adafruit boards not working with arduino on Mac

Post by smitheken »

I have a lot of adafruit boards and now none of them are working with arduino, I checked my arduino with a uno r3 and a 2560 and they both show up on the ports. I have a mac 12-4 OS, every thing was working before i upgraded now only adafruit boards are not working. It has to be some thing with a driver. I ls /dev/* to see a complete listing and when a adafruit board is plugged into the usb port it does not show up.

I could use some help and it seems like other people are running into similar problems.

The boards I used to are as fillows
1. Itsy bitsy 5.v
2. Metro MO express
3. metro ESP32-S2
4. Huzzah

all boards had program on them.

all of the boards were working before the upgrade to mac 12.4. This is the only change.

A Uno r3 works, 2560 works. Just none of the adafruit boards.

I figure it must be a driver issue and mac has eliminated some thing on there upgrade.

Some of the boards you listed use generic USB firmware, and others use the CP2104 USB-to-Serial converter. There's no common driver for them.

Try putting a cheap/old USB-2 hub between the Mac and the microcontrollers. USB-3 begins its hardware recognition process with a burst of 480MHz data. That's enough faster than the CPU clock of any microcontroller you listed to look like random noise. Sometimes that can make a bootloader's USB code crash. The hub will block those high-speed signals, giving the microcontrollers a better environment.
