Hi Lighting Controller
After spending many hours working on this problem I am convinced the Drivers.zip file (dated May 2018) you make available to download from this site and extract various driver file sets do not work under the latest Windows 10 version V20H2 64-bit, released February 2021.
I have tried installing each version of the 64-bit and 32-bit EFKcable and EFKusb drivers in turn and rebooting the PC on each install but I still get the error message in Driver Status that says:
The drivers for this device are not installed. (code 28)
There are no compatible drivers for this device.
To find a driver for this device, click Update Driver.
On each reboot after trying a different version of EFK driver, the Windows Device Manager displays a yellow ! against the USB Serial Port device name.
Removing the Xpress-100 USB-to-DMX cable from the PC makes the USB Serial Port device disappear from the Device Manager. This clearly indicates the PC is seeing the Xpress-100 when it is plugged into a USB port of the PC.
The latest version of ShowXpress (v9.2.23) is installed on my Windows 10 PC (AMD Athlon II X2 250 Processor 3.00GHz, 6GB RAM).
When the software is launched a ShowXpress Startup window briefly appears that states:
Starting...
default
1 Interface found
Xpress100
0 Artnetuniverse available
This indicates the software is detecting the Xpress-100. If ShowXpress is launched without the Xpress-100 plugged in the Startup window states:
Starting...
default
0 Interface found
0 Artnetuniverse available
The above information convinces me that ShowXpress is able to see the Xpress-100 cable but Windows 10 does not accept any of the EFK drivers you provide.
Are you able to provide a solution to this problem please?
Best regards
