any usb to serial cable driver for MACOS Montery.

when i had MAC bigsur everything was working perfect and i can console to my devices now i cannot anymore, this is due to missing usb to serial cable driver after the update to macos montery.
 
Where did you get the driver for Big Sur? Won't that work in Monterey?

I would be surprised if Monterey changed much to affect the serial driver. Perhaps you might reinstall Serial and see what happens.

Use Homebrew lsusb to see if the system sees the USB serial dongle:

https://formulae.brew.sh/formula/lsusb

Code:
lsusb -v
USB:

    USB 3.1 Bus:

      Host Controller Driver: AppleT8103USBXHCI

    USB 3.1 Bus:

      Host Controller Driver: AppleT8103USBXHCI

        usb serial converter:

          Product ID: 0x6001
          Vendor ID: 0x0403  (Future Technology Devices International Limited)
          Version: 4.00
          Serial Number: ftDI
          Speed: Up to 12 Mb/s
          Manufacturer: ftdi
          Location ID: 0x00100000 / 1
          Current Available (mA): 500
          Current Required (mA): 44
          Extra Operating Current (mA): 0

Then, see if a tty has been established usually using the serial number as name:

Code:
ls /dev/tty.usb*
/dev/tty.usbserial-ftDI

Then, test connection:

Code:
screen /dev/tty.usbserial-ftDI 9600

I use a Cables Unlimited USB-2920 that's plug and plug on Monterey, Windows, Linux, etc. and has been 100% reliable for data center/MDF/IDF stuff.

I've plugged a USB-Serial adapter into my Monterey MBP that contains an FTDI chipset. It's working as expected using the 'screen' utility in Terminal. The adapter is embedded in a proprietary board, but works with that chipset. To the OP, maybe trying something with an FTDI chipset? They are pretty common in the USB-Serial world in my experience. Note that I have an Intel MBP if it matters.
