Only in very rare instances we have learned about problems with Docklight USB device drivers, which are installed automatically by Windows when plugging in the device.
If a Docklight hardware accessory is not accessible as expected, we recommend removing and re-installing the Windows 10 drivers, according to the “FTDI Windows 10 Installation Guide”, section 4, “Uninstalling FTDI Devices”:
1) Open the Windows Device Manager (Windows key + R, then type “devmgmt.msc”)
2) Find the device in the device tree inside the “Ports (COM & LPT)” branch, e.g. as “USB Serial Port (COM5)”.
3) Right mouse click and choose “Uninstall Device”.
4) In the “Confirm Device Uninstall” dialog, check the option “Delete the driver software for the device”.
(Using the FTDI utility “CDM Uninstaller” as mentioned in the FTDI guide is also possible)
5) Repeat steps 3+4 in the “USB Controller” branch where the device should appear as “USB Serial Converter”.
6) Unplug the Docklight Tap / Tap Pro / Tap 485 / Docklight RS232 Adapter device and replug in.
The device should appear now temporarily under the branch “Other Devices” as “USB Serial Port”.
7) Wait until Windows performs the automatic driver installation (Internet connection required).
