SRG50

I tried the FTDI driver and Win11 and/or the 23150 did not like it. However, Windows did offer me a solution which was to disable core isolation memory integrity. I did that and the 23150 led lit up and it had loaded the Lenz Win10 drivers. All good I thought until I tried to enable core isolation and it identified the Lenz and FTDI drivers as having issues that needed to be resolved before proceeding. Unless there are other suggestions, I think the solution offered by Iain of purchasing a 3rd party DCC USB interface may be the sensible route.

Thanks for all your assistance Iain. Several things for me to chase down. A search of the internet for a driver came up with website called DRIVERSOL and they state FTDI have updated driver for Lenz LI-USB as per the image below. I have no experience with DRIVERSOL or FTDI. When I clicked on 'INSTALL DRIVER" it gave me an updater.exe. I am wondering I should try the FTDI generic VCP driver and see what happens!

Unfortunately, my new laptop/computer does not have an ethernet port.

I recently upgraded from Win 10 64bit Pro to a new computer with Win 11 64bit Home. I had successfully installed the drivers for the Lenz 23150 on the Win 10 computer after disabling the requirement for signed drivers and all was well. I have been unable to locate Windows 11 drivers for the device. I tried installing on the Win 11 computer following the Win 10 protocols but Windows will not install the drivers and I receive a Code 39 error message. Is it the end of the line for my 23150? What are my options?
