I have removed the device (and drivers) several times, re-installed drivers several times, but still this issue persists. ShowXpress still cannot see the Xpress 100 Cable interface.
After removing the device and drivers in Device Manager, then plug my Xpress 100 device in. Windows immediately detects it, and installs drivers as shown ....
In "Other Devices" : "USB Serial Port", warning triangle : Properties say "The drivers for this device are not installed. (Code 28)", location "on CABLE interface 64bits (2017_07).
In "Universal Serial Bus Controllers" : "CABLE interface 64bits (2017_07)" : Properties say "This device is working properly."
At this point, I can start ShowXpress, and it DOES find the interface, and I can work with it. But this is not the latest driver software, and I still have that "USB Serial Port" entry in device manager.
So, I update the driver manually, from the Drivers.zip files you linked to, and then restart the PC (it tells you to).
After doing that, the "Other Devices" : "USB Serial Port" is not there in Device Manager, and the "CABLE interface 64bits (2017_07)" has been replaced with "CABLE interface 64bits (2018_04_25)", but this has a warning triangle, and the device properties say "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)", and of course ShowXpress cannot see the interface.
For now, I will use the "CABLE interface 64bits (2017_07)" driver, because it works, but there must be an issue with the "CABLE interface 64bits (2018_04_25)" driver.
