It has the usual tradeoffs of open source stuff.  On the one hand, I  
might be able to fix it (try that if your USB-including micro doesn't  
work!  How many PIC/USB projects support the full communication error  
handling?  I imagine that takes some software as well as on-chip HW  
support?)  On the other hand, it'll probably never be fully compliant  
and might break something that ISN'T fixable...

(On a vaguely related issue, I recently had cause to recommend an  
FTDI chip for an app that needed a USB/Serial bridge.  Cause I *knew*  
it worked on linux and macos as well as windows, whereas other  
vendors were only doing windows + promises.  Alas, FTDI is not on the  
"approved vendor" list for single-source parts, and we went with  
someone else.  Hopefully things will work out OK.)

Doesn't seem past the vaporware stage.  Eagerly awaited.
