Windows:

Aug 13, 2016  The primary issue is that FLdigi or WSJT-X stop communicating with the PL-2303 USB driver when they conflict. (Start both Programs). When this happens I have to Force Quite the application. It however, fails to release the PL-2303 driver in the OS and it remains visible under System Information / USB. (It's providing Cat Control to a TS-2000).

No driver installation is necessary for Windows 10, 8.1, 8, or 7 computers that are connected to the internet. The operating system will download the correct drivers automatically when the Plugable USB to RS-232 DB9 Serial Adapter is plugged in. For all Windows XP and Vista systems and for Windows 10, 8.1, 8, and 7 systems that are not connected to the internet, please download and install the following driver:

This driver file contains the following software versions:

The adapter uses the standard USB Prolific VID and PID of 0×2303, which is recognized by all of Prolific’s standard drivers.

There are a couple different USB to serial adapters that you might use as a network engineer. The one pictured in the article is manufactured by Prolific, but sold by multiple different vendors. There’s also another manufactured by FTDI, which I’ve heard good things about, and of course the one built into recent Cisco hardware. The driver for the chip used by Cisco is conveniently included in OS X, but the FTDI and Prolific chips require their own drivers. Myself, I have used the Prolific cables for years and have been generally happy with them.

The best drivers for the Prolific come directly from the manufacturer, not the vendors that resell them. This is because the vendor provided drivers always seem to be out of date. However, the drivers from Prolific don’t work with all cables out of the box. I’m going to show you how to fix that.

1. Get the Driver

If you haven’t already, hop over to the Prolific site to download the driver and install it. Here’s the URL at the time of this writing:

If you are running OS X Yosemite, you may need to read this article to get the driver working: OS X Yosemite and Prolific USB Drivers.

2. Discover Magic Numbers

OK, the numbers aren’t really magic, but the driver will need them so that it can be associated with your USB device. Head to Apple -> About This Mac and and choose System Report. Select USB and scroll until you find your Prolific USB device. It should look something like this:

Watch for the Manufacturer (circled in blue). Then note the Product ID and Vendor ID (circled in red). Update flash mac os. We will be adding these to the driver.

3. Hex to Decimal Conversion

Calculator in hex mode

ExFAT also performs better than FAT32.You can format the drive from either the Mac or the Windows machine. However, if you want to use part of the drive for OS X's Time Machine backups, you should do this from the Mac, since there's an extra step to make the drive compatible for Time Machine. Mac os x format hard drive ntfs.

We need to convert the hex numbers to decimal. An easy way to do that is to run Calculator and hit Command-3. Click the “16” above the clear button to switch to hex and enter the number you want to convert (like 0x2008 from the example). Now click the 10 and you have the hex to decimal conversion. If you used 0x2008, you should get 8200. You need to convert both the product and vendor IDs.

4. Edit the Driver

At this point, you will need to either fire off a root shell or sudo everything.[1]

Safety First! Backup your Info.plist so you can fix the driver if you break it.

Edit Info.plist with your editor of choice. Scroll down and you will find a section that looks like this:
[code language=”xml”]
<key>0557_2008</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.prolific.driver.PL2303</string>
<key>IOClass</key>
<string>com_prolific_driver_PL2303</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>0</integer>
<key>idProduct</key>
<integer>8200</integer>
<key>idVendor</key>
<integer>1367</integer>
</dict>
[/code]

What you want to do is copy and paste that section. I don’t think the <key> actually matters, but you can change it to match the hex version of the vendor and product ID. So if your vendor ID was 0x2478 for Tripplite with a product ID of 0x2008, you can change the key for your new section to:
[code language=”xml”]
<key>2478_2008</key>
[/code]
Then you will want to put the decimal version of that you converted before into the idProduct and idVendor sections. So for the Tripplite example you only need to change the idVendor and it would look like this:
[code language=”xml”]
<key>idVendor</key>
<integer>9336</integer>
[/code]

So the final product for my Tripplite version of the Prolific adapter works when I have this section added:
[code language=”xml”]
<key>2478_2008</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.prolific.driver.PL2303</string>
<key>IOClass</key>
<string>com_prolific_driver_PL2303</string>
<key>IOProviderClass</key>
<string>IOUSBInterface</string>
<key>bConfigurationValue</key>
<integer>1</integer>
<key>bInterfaceNumber</key>
<integer>0</integer>
<key>idProduct</key>
<integer>8200</integer>
<key>idVendor</key>
<integer>9336</integer>
</dict>
[/code]

5. Kick the Driver
