Prolific Usb To Serial Driver Ubuntu

Sharing a Prolific USB-UART Converter with VirtualBox 04 Apr 2016While creating a UART protocol for use in a new product, itbecame useful to connect a serial adapter from my host PC to the Vagrantenvironment which held the protocol code and its dependencies. This approachshould work regardless of the UART converter model/brand (Prolific, FTDI, etc)assuming that plugging the device in creates a /dev/ttyUSB0-9 entry.

Thisguide is written for a.nix host platform (Ubuntu).First Things FirstThe adapter which was used to test this approach is similar to theavailable on Adafruit; but any similar adapter should work. Step-By-Step.Plug in the USB-Serial adapter, and ensure that it shows up under lsusb, as well as creating a device entry similar to /dev/ttyUSB.Once the adapter is plugged in, execute chmod 666 /dev/ttyUSB0 (substituting ttyUSB0 for whatever USB. port the adapter enumerated to) on the host machine. Determine the adapter by observing what new entry is added to the outputof ls /dev/ttyUSB. when the adapter is plugged into the host machine.Alternately, ensure that the user running the VirtualBox on the host machineis in the dialout group ( sudo adduser $USER dialout).

This requires alogut/login cycle to take effect. In the VM VirtualBox Manager GUI, go to “Settings” for the machine whichwill receive access to the serial port, and navigate to the “Port 1” tab under“Serial Ports”. Set “Port Number” to “COM4” (corresponding to a guest VM serialport of /dev/ttyS3), leave IRQ and I/O port as their defaults, select“Host Device” as the Port Mode, and type the path to the serial port deviceon the Host machine under “Port/File Path”. In this example, this is/dev/ttyUSB0.On the guest sudo adduser $USER dialout will add the guest user to a groupwhich has access to the serial port interfaces (e.g. Execute this command, then log out and back into the guest machine.Ensure the TX/RX lines are connected together on the serial adapter forthe next step (a loopback test from the guest VM).Log into two separate terminal sessions on the guest VM, in the firstsession, type cat /dev/ttyS3. In the second terminal session, typeecho 'test' /dev/ttyS3.

If the serial device from the host is beingsuccessfully passed through to the guest, “test” should appear in the windowwhere cat is running.At this point, the guest VM has access to read and write to a USB serial adapterconnected to the host machine. Note that this approach does not require theguest VM to have any direct USB peripheral access to the host. Asides.is an extremely useful library for abstracting away most of thecomplexities involved with programmatically accessing a serial port for UARTcommunications.If also occasionally using the serial port outside of the virtual machine,note that if the virtual machine is currently accessing the serial port (e.g.the host is passing the serial port directly through to the VM) there will beproblems attempting to use it on the host at the same time.This approach might not be suitable for near-realtime response requirementson the serial lines.

Dear Customers,We are glad to announce the release of our Windows 10 WHQL driver for PL2303 USB-to-Serial/UART Controllers.The PL2303 Windows 10 driver can also be downloaded automatically via Windows Update. Just plug-in the PL2303 USB Serial device and Windows Update (Internet connection is required) will download and install the latest drivers.NOTE:. Windows 10 is NOT supported in PL-2303HXA/XA EOL (End-of-Life) chip versions. Prolific recommends to buy chip or newer generation chip versions.Or.
