I use the old version PL2303 in a some homebrew projects here (unrelated to the TX500); with Windows 10 64 bit version, I found it was necessary to uninstall/remove any driver PL2303 Windows 10 tried to install on it's own, then manually install the old version PL2303 driver (I believe 1.5.0 but the driver from LAB599 would work too), then "disable automatic driver downloads" (a setting in Windows 10). This worked (that is, stayed operational across reboots and shutdowns) UNTIL I did a feature update for Windows 10, at which point I had to repeat this entire procedure as the feature update evidently brought with it the automatic-but-nonfunctional driver.

This is very well-known issue with prolific. Can't recall details, but they essentially blacklisted older models because they were cloned too much. Doesn't matter if you have genuine version or "pirated" clone, it's in blacklist.
I have bunch of those USB-COM adapters and they all do that, despite being genuine.
My tx-500 was supplied with FTDI-based cable so it doesn't have this problem.
Has you tried manually overriding drivers with ones provided by lab599?
If this fails, i can send you old (2008) drivers that works with olded PL2303 chips, i use them pretty often on win10. Should probably work with HXA too.
