Advanced Settings on the Prolific USB to Serial driver
You can change the port settings on the Prolific USB to Serial Adapter settings as shown below. You will need to click on the port options on the top of the menu and then click on the advanced options which holds the advanced port options on the Prolific adapter as shown below.
Note what each of these advanced port settings does as shown below:
- USB Selective Suspend Idle Timer
This is the Idle Timer for the PL2303 chip to enter suspend mode and the default for this is 10 seconds. You can change this on the Prolific USB to serial adapter. Check your chip as this does not work on the PL2303SA chip. Also note that for the PL2303HXD/EA/RA, you need to write to OTPROM first.
- Disable DTR/RTS INIT signal
By default this is enabled. This will disable the DTR/RTS pin initialisation signal during driver load to disable the serial mouse or modem from being detected. Check this setting if your Prolific USB driver is not detecting your serial modem or serial mouse. The Prolific USB to Serial Adapter normally has this enabled as stated before, however for troubleshooting it is always best to check the advanced settings.
- Change DTR/RTS INIT Level Shift
The signal needs to be enabled as the default for this setting is TTL=HIGH as well as RS232=LOW.
- Disable Device USB Serial Number in Windows Registry
This is very important if you have many devices. The default for this settings is enabled. If you check this it will ignore PL2303 device Serial Numbers. If you disabled this then each PL2303 device even with different USB serial numbers will be treated as same device. This is more for troubleshooting your serial devices.
- Driver Buffer Size
This will set the buffer size of the serial device. The default settings for this is 4096.

USB port types and names
USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model:
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.
Learn more about identifying the ports on your Mac, as well as the adapters and cables you can use to connect older devices to type USB-C ports.
USB specifications
USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2
Also known as USB 3.2 Gen 2
Up to 10 GbpsUp to 15W at 5VUSB 3.1 Gen 1

Up to 12 MbpsUp to 500 mA at 5V
To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
- Choose Apple menu > About This Mac, click Support, then click Specifications.
- Check the System Information app for more details, including about USB devices connected to USB ports on your Mac. Select USB in the sidebar, then select a USB bus on the right.
Get the best performance from your USB devices
USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.
If your Mac doesn't recognize a USB device after you plug it into your Mac:
- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.
