Oliver is more experienced in reading the CONFIG_USB_DEBUG output (which
I'll send you offlist), but the basic symptom is that the Palm 700p
i) gets recognised and mapped to ttyUSB1 upon connection via the usb cable
ii) but starting to sync drops and then reconnects and it somehow ends up as
ttyUSB3, and I was never able to get data exchanged (using either
pilot-xfer or jpilot) with ttyUSB3.
Not setting CONFIG_USB_SUSPEND makes the Palm 700p more 'sticky' and it stays
at ttyUSB1. It is still finicky -- I have to initiate suspend on the device,
wait for it to show the actual start on its screen and then launch the Linux
app. My Tungsten C is way more robust in that regard, and I'd be glad to be of
help.
Cheers, Dirk
