Update which OS/distro, from what version to what other?

This sounds vaguely like the behavior with my Treo 700p.  With this
device I cannot get visor to work at all.

With libusb, I need to control the timing very carefully: if I hit
hotsync on the Palm two to five seconds before the computer starts
listening, it works.  Less than two seconds before, or more than about
ten seconds before (never checked this timing precisely), or Palm after
computer, and it fails.  And by "fails" the gpilotd or pilot-xfer goes
into some kind of infinite loop as you described and needs to be killed.
So try a few different timings before/after and see if anything works.

It's easiest to check this by pausing the gpilotd daemon (kill it if
it's infinite-looping), and check the timing of something simple like
"pilot-xfer -p usb: -l".

Also, make sure it's not reloading the visor module, which would
interfere with libusb.

I have no idea what's actually happening which makes it fail/succeed...

Hope this helps,
-Adam
