They work GREAT, Denny. smaller chip than before, and NO
clock is needed; in fact it can SUPPLY 6M/12M/24M your choice.
The clock is sync'd to the USB Port clock, so is very precise.

There is another neat feature of their latest driver... You can tell it
to maintain the SAME comm port (turning off PC power normally
causes the VCP ports to shuffle around).

Finally, you can write descriptions into the device and WinXP will
display them when the product powers up and enumerates!

I designed in the chip twice this year.
