Linux Mint VirtualBox HOST + Windows XP 32bit GUEST. The 1st FTDI based adapter I purchased didn't want to find a driver (from the FTDI site - not clear AT ALL!) that would allow it to function. It essentially worked with Linux etc... but not specifically here, in my specific setup. This UGREEN adapter worked PERFECTLY. The driver was clearly marked and installed like a dream on XP. A rule in life: Not all things work all the time in every situation. Even identical items. p.s. The Ugreen (non-TEMU) packaging was first class and the physical cable was, wait for it... yes, 1st CLASS :) Even if had not worked, you felt like it could have and it had to be the installers fault.
