I honestly do not know. I use two main 'client' programs -- jpilot and
pilot-xfer -- and neither communicates 'well' (in the sense of how being
equivalent to my old Handspring Visor and my Palm Tungsten C, or my wife's
Treo 300) with the Palm 700p. I do not know the kernel usb stack well enough
to assess who's fault this is -- the usb controller, the visor driver, the
kernel ... . I just know that my user experience is not anywhere near where
I'd like.
It seems to me that the Palm 700p uses a variant of the communications
protocol. E.g. one of our older Linux workstations doesn't even recognise
it, yet has worked flawlessly for years with the 700p.
What's your take?
Thanks, Dirk
