I just got my Z. After several attempts to get it to sync properly, I finally figured out that I can sync directly from Lotus notes to my networked 5500. I thought I had to go from Notes -> Qtopia Desktop -> Zaurus (and vice versa).
Anyway, in the process of figuring this out, I must have installed and uninstalled the Windows USB drivers for the Zaurus 15 times. At some point along the way, Win2k stopped asking about the USB network driver. And now, no matter what I do, I can't get it to install that driver. Additionally, when I plug the Z into the cradle and turn it on, Win2k pops up the hardware detection routine (which says that it's detected an SL-5500), but when I try to tell it to use a particular driver, it won't.
The long and short is that somehow I've fubared the driver configuration of Windows. And I can't get it to work anymore. I've tried uninstalling the drivers using the standard uninstall wizards, etc. And I've gone into device manager and removed the devices from there. Any suggestions as to what I should do to get this to work? I'm currently syncing using a wired CF network card. I'd like to sync over USB net.
