Yes I had the same problem. I think the problem will be 
solved once you have the dongle. The problem is that
the chip will fail to go into programming mode since
Vdd is before Vpp. However xwisp2 should probably time
out and not staying there. I will check with 
the author about this again. I will also make this dongle
and try it as well but I do not quite like this idea
especially for off-line program. (Take note Wisp628 is
designed to be a on-line ICSP programmer.) I think to add a
Vdd-target and Vpp-target and using two port pins like 
PICkit 1/2 will be better option. Anyway maybe we need
to wait Wouter to release Wisp648 or Wisp2550 for this
to happen. ;)-

  I will try to make the dongle and test.

  I downloaded the executable for xwisp2 from http://www.robh.nl and 
tried it but all I got was:

C:\xwisp2>xwisp2w go prg.hex
 xwisp2 version 1.7.00 (Sep 10 2005, Open Watcom C 1.30)
File prg.hex loaded and is Intel Hex format conforming

 And I had to use ^C to finish the endless loop. Did you have any 
trouble like this too?
