I’m on Mavericks (10.9.5) and fighting with a USB device with a “FT232R” chip (from FTDI) for USB to serial conversion.

To see if you have the latest, most compatible device drivers installed. It can determine which Gigabyte GA-8I945GZME-RH Motherboard Drivers For Windows 7 are either missing, corrupt, or have become obsolete. Canon drivers for mac. Before install the new drivers, Easy Driver Pro backs up your existing Drivers and settings to create a restore point just in case one of the Gigabyte GA-8I945GZME-RH Motherboard Drivers For Windows 7 turns out to still be incompatible. Next, Easy Driver Pro searches a database of over 11 million drivers and matches missing, corrupt, or obsolete Drivers to the latest, most compatible drivers for your operating system.

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.

In this tutorial, we’ll show you how to install FTDI drivers on windows operating systems. How to install Ftdi usb Driver?? 1.Uninstall any previously installed Ftdi Drivers.(Highly Recommended). The COM stands for 'communication', and each one has a unique number, known as the COM Port number. In this case the COM Port number is COM3. If you don't see the COM port verify the cable is plugged in, and check that you installed the VCP FTDI driver.

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.

But I want to get rid of the Win (VM) solution and installed the FTDI driver for Mac, didn’t work.

As suggested by FTDI for Mavericks

I have also disabled (renamed) the AppleUSBFTDI.kext, restarted and installed the FTDI driver (version 2.3, signed by Apple). 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've tested this on APs with Open, WEP, and WPA2 security, reset routers, etc. Intel wifi link 1000 bgn driver for mac. I've tried re-installing the manufacturer's drivers, installing Intel's drivers (which for some reason cause the adapter to be shown as an Intel Centrino-N wireless adapter rather than an Intel Wifi Link 1000), disabling 802.11n mode, disabling the 'Allow computer to turn off this device to save power', ensuring that transmit power is at the highest, roaming is at medium, switched through channels. Performance is exactly the same, basically bouncing off access points with four bars or less of signal strength. After a bit of trial and error I realized that, though the adapter detects all the networks it used to at the same signal strengths, it's unable to connect to anything that's basically not at full signal strength (pretty much beside the computer).

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?

Could someone help, please?

(I have little knowledge in OS X)

For a recent project, I needed to interface my computer to an embedded device over a RS-422 connection at 3.2Mbaud. Since this is a nonstandard serial rate, I set out to find a way to configure a relatively cheap USB UART bridge that supported communications at this speed.

FTDI makes a chip called the FT4232 that has four separate UART interfaces and supports baud rates from 3MBaud to 12MBaud using some extended clock settings. These extended baud rates are readily available with FTDI’s D2XX drivers, but I wanted to retain the ability to use a standard serial programming API to communicate with the hardware. As such, I was left with the task of aliasing some other standard baud rate to 3.2MBaud in the virtual com port drivers.
This is a task FTDI has outlined quite well for windows in an application note, and it is also buried in a application note for Mac OS X. I only located the Mac OS application note after figuring out the procedure myself, so I’ll break it down here for you.

Ftdi Drivers For Windows 7

1. Install the FTDI VCP Drivers for Mac OS.
2. Grab the VID and PID of your USB UART adapter, and convert them to decimal. These can be both be found under the device properties within the system profiler. Conversion to decimal can be done by googling “0xHEX_VALUE to decimal”. In the case of my FT4232, where I was interested in aliasing baud rates for port C of the device, the hex VID PID pair are 0x0403 and 0x6011, which translate to 1027 and 24593 decimal accordingly.
3. Open the FTDI driver’s Info.plist in your favorite text editor as administrator. The Info.plist file can be found at /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist
4. Locate the driver entry associated with the decimal encoded PID and VID of your USB device. The block of XML you’re interested in will look something like this:
   
5. Below the vendor ID configuration entry, add a new dictionary with a key of “ConfigData” to configure the baud rate alias you would like to set up. The last few lines of your device-specific configuration will then look like this:
   

   As you can see, there’s a new key called “BaudRates” with an extra dictionary mapping standard baud rates to custom ones. Here, I’ve aliased 300 Baud to 3.2 MBaud. This section can also configure other functionality of the device, for which you should refer to the FTDI docs.

6. Unplug your USB device.
7. Unload the FTDI kext bundle with
   sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver.
8. Reload the FTDI kext bundle with
   sudo kextload -b com.FTDI.driver.FTDIUSBSerialDriver.
9. Replug your USB device.
10. Celebrate! Any serial connection you open at the standard baud rate you’ve aliased should now use the other clock rate you’ve specified.

Take care when configuring arbitrary serial baud rates. The clock divisors in the FT4232 and other FTDI chips have limited configurability. As such, it can be very easy to wind up with large enough of a clock skew (1-3%) between two serial devices to cause communication issues. For details on the clock rates your particular FTDI chip can achieve, take a close look at the baud rate calculation section of the Windows baud rate aliasing guide.
