VCP drivers for windows work great and its stand alone you just need to connect TX/RX and ground.

Pretty neat! Will it work under 98SE?

I suspect it's an FTDI chip on a neat little PCB- so the answer is probably yes.

Its a Silicon Labs CP2101 according to the datasheet in an MLP form factor (5mm square). Neat though - minimal external components required.

Yeah it works on its own - you dont have to have anything else there, just the HR-USBUART connected to your micro via TX/RX and ground.

Yes, kind of like we did making a board that has pads and holes in the same pattern as a DE9 so we could retrofit our RS-232:

Before using that chip, think about the company politics about not releasing a linux open source driver

yea, it has a internal 48Mhz oscillator, I wonder if thats just a trimmed R/C oscillator, usually they aren't good enough for serial timing,

Presumably it is phase locked to the incoming USB clock so it will be as accurate as the PC's clock.

But you have designed them, haven't you? So you can provide the exact answer.
