Comment 24 for bug 66355

There is more info attached to the upstream bug, but the summary so far is:

some palmos devices appear to have problems if a sync is attempted immediately after the device connects to the host computer. gnome-pilot 2.0.14 uses HAL to detect a palmos device, and so tends to attempt a connection considerably faster than in 2.0.13 and earlier.

It's not clear what is causing this problem, but it seems to be in the usbserial / visor module case, so configuring libusb is a good workaround. Disabling HAL before attempting a sync also appears to work.

A patch is being worked on, and a testable gnome-pilot tarball can be downloaded from the upstream bug.
