I’ve adapted the electronics of that device (stripped the internal RS232 to TTL converter electronics for the uP, added the the USB socket and USB-TTL conversion with FT232R) to connect to modern computers. I’d send a (serial) “request” and the device will answer accordingly, e.g. The device is a test equipment with a serial port, originally RS232 (+/- 9V, DB-25). Nope, not visible in Finder or Disk Utility, it’s not a drive, it won’t reply without a command.
#Usb to serial mac driver driver
I’ve tried again and again, there is no FTDI or USBSerial device listed in /dev when I plug it in or switch it back from Win - I guess because the (OS X) driver isn’t correctly installed?

The installer always tells me “success” but I still can’t see the driver /System/Library/Extensions/FTDIUSBSerialDriver.kext (should it be there?) and the device isn’t accessible from OS X. I have also disabled (renamed) the AppleUSBFTDI.kext, restarted and installed the FTDI driver (version 2.3, signed by Apple). In OS X it seems to be unknown, however, the USB Device Tree reports the FT232R USB UART correctly with Product ID and Vendor ID from FTDI.īut I want to get rid of the Win (VM) solution and installed the FTDI driver for Mac, didn’t work. Using an old Windows (in a Parallels VM on the same Mac) I could (and still can) access the device, switch it back and forth between OS X and Win, and send commands to it using a terminal SW. QuickTerm didn’t list it, only the Bluetooth Port + Modem). I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.
