I am in the process of moving a virtual machine from a T7610 to a T7910. Both computers run Windows 10 Pro 21H2, but for some reason the T7910 refuses to perform a complete installation of the hardware lock driver required by software installed in the virtual machine. Here is a comparison after driver installation:
T7610 Driver Installation StatusT7910 Driver Installation Status
As can be seen, the “System” installs the USB driver on both computers without issue, but not the parallel driver. I should add that I am using a legacy parallel port adapter card installed in the PCI (not PCIe) slot, which allows the manual selection of I/O port addresses by the use of a jumper. When properly configured it appears as an ECP port in Device Manager. Both computers report that the ECP port is working properly with no conflicts. Moreover, the PCI slots are good, and the parallel port system driver is running in Windows, so what may be causing this behavior? Is the “System” Windows itself or the computer?
The BIOS is different in the two computers, but yes I did. The only thing related to PCI in the T7910 is the ability to turn the slot on or off. Are you thinking of something else?
Another possibility is to buy a newer T5820 or T7820 because they are the most recent models to include a PCI slot. Unfortunately, the T7920 no longer does. What’s in the BIOS of your T7820?
I know, just in general the settings being offered should be more or less the same. And maybe something else is set differently between the 2 units.... just thinking out loudly.
I don't remember specific pci settings here, aside the usual legacy rom
I have an idea! We should be able to test this on other T5810, T7910, T5820 and T7820 computers, WITHOUT installing any hardware, simply by adding an ECP port and then installing the driver. All this is free, safe, and fully reversible so please join in if you care to. I would especially like to hear from other T7910 owners, just in case I have a lemon. Thanks in advance!
STEP ONE: CREATE AN ECP PORT
Open Device Manager
Left click on your computer name;
Left click the “Action” menu and then “Add Legacy Hardware”, Next
Select “Install the hardware that I manually select from a list (Advanced)”, Next
Select “Ports (COM & LPT)”, Next
Select “ECP Printer Port”, Next and then Finish to create a new LPT3 port.
NOTE: In Device Manager the newly created ECP port will have an exclamation mark.
Right click it and select “Properties”
On the “Resources” tab click “Set Configuration Manually”
In the next dialogue highlight “I/O Range”, uncheck “Use Automatic Settings”, then click “Change Settings”
Select the range value (I use 0278-027A), make sure no devices are conflicting, then OK then OK

Hello,
have you tried comparing the bios settings in both computers ?
