UT-D04 cable refused to connect and therefore I was unable to collect data via USB from my UNI-T multimeter. The cable worked with previous instance of Win10 and still works when used under VirtualBox'ed Windows XP, so hardware failure was ruled out.
After quick internet search, drivers were the suspect.

this USB interface appears to be compatible only with Windows, including software to read and acquire data. The most serious thing is that the available drivers are compatible only up to Windows 7 and I have not been able to find a way to make the device recognized by Windows 10
Windows 10 seems to have multiple drivers for CH9325 USB interface chip. Look for a device with VID/PID 1A86:E008
- Verify how is the device currently indentified and what drivers are used.
If you see "USB to Serial" using
libwdi
driver, change it.
Right click > Driver> Update Driver > Browse my computer for drivers > Let me pick from a list of available
Change driver toUSB Input device
- Verify the chip is now listed as
Human Interface Devices (HID) > USB Input Device
with a Microsoft driver.
- sigrock-cli visibility verification
sigrok-cli.exe --list-serial
Following sigrock-cli command should detect the CH9325 even when using the libwdi
driver
C:\Program Files\sigrok\sigrok-cli>sigrok-cli.exe -d uni-t-ut71d:conn=1a86.e008 --scan
The following devices were found:
uni-t-ut71d - UNI-T UT71D with 1 channel: P1
