Which USB chipset do you have?  I have seen at least 2.6.18 fail to run
USB2 devices on some SIS chipsets, while if ehci-hcd module is unloaded
(making it USB1 only) everything works fine (although at USB1 speeds of
course).  Might be related to your problem.

Of course you probably also need much newer sync software for the pilot
than comes with sarge.  My tungsten E can't sync with sarge, although it
seems to have better luck with what is coming in etch.
