Date: October 26, 2023 | Category: Drivers & Firmware | Reading Time: 6 minutes

Before You Begin

  • A Windows-based PC (Windows 10 or later recommended)
  • A blank USB flash drive (formatted to FAT32, minimum 8GB capacity)
  • Stable internet connection for downloading the software package
  • Admin access to the target device (if updating firmware)

4. Linux (Ubuntu/Debian) users

  • Fix: Do not download anything. The kernel includes CH340 and PL2303 drivers. Run: 
    sudo modprobe ch341
dmesg | grep tty
    Your device will appear as /dev/ttyUSB0.

1. Identify the Actual Chipset

The TPRD8503PB816 is almost certainly based on a common USB bridge chip. The most likely candidates are: tprd8503pb816 usb software download top

  • Prolific PL2303 series (very common for USB-to-serial)
  • CH340/CH341 (WCH, extremely common in cheap USB adapters)
  • FTDI FT232 (less likely but possible)

How to check:
Plug in the device. Open Device Manager → Right-click the unknown device → Properties → Details → Hardware Ids. Look for VID_xxxx&PID_xxxx. A Windows-based PC (Windows 10 or later recommended)

  • VID_067B = Prolific
  • VID_1A86 = WCH (CH340)
  • VID_0403 = FTDI

How to "Program" It (The Manual Method)

Since there is no USB software, all adjustments are done manually on the hardware: 4. Linux (Ubuntu/Debian) users

  • Operation: Press the button on the left side of the laser housing to turn it on. Press again to turn it off (some modes allow a double-tap for a pulsing beam).
  • Zeroing (Sighting In): You do not download software to align the laser. You must manually adjust the windage (left/right) and elevation (up/down).
    • Look for the small adjustment screws on the laser housing.
    • You will need a very small Allen wrench (often included in the box with the gun). If you lost it, a standard hobby Allen wrench set (usually 1.5mm or smaller) will work.
    • Adjust the screws while aiming at a target 10–15 yards away until the laser meets your point of impact.
