Royal ezVue 5 PDA

My wife recently bought a Royal ezVue 5 PDA, as an inexpensive way to find out if she would use a PDA. It's a fairly nice unit with plenty of built-in applications, and it comes with PC synchronization software.

I ran into a fairly significant problem after installing the software on Windows XP : her USB scanner driver stopped working. After much tinkering I got things working, but it was a bit of a pain.

  1. I set up 2 hardware profiles, which I called "Scanner" and "PDA". In the "PDA" profile I disabled the USB scanner.
  2. I told the PDA sync software "SmartSync" to not start up automatically at boot-up
  3. I leave the PDA USB cable unplugged until she'e ready to synchronize.
  4. To synchronize :
    1. Boot into PDA hardware profile
    2. Plug in the PDA USB cable, with PDA off
    3. Start the SmartSync application
    4. Turn on the PDA and initiate synchronization

Also, it appears that the synchronization will often duplicate address-book entries. I haven't done enough testing to confirm this, and I have no idea why some entries would be duplicated and some not.

Installation

Be sure to follow the instructions : install the software before plugging in the USB cable. If you plug in the cable then try to install, you'll get a message about "an instance of this driver is already loaded". Also, no matter how you install it, when you first plug in the cable XP will complain about the "Megawin USB Bridge" software not being XP logo compatible. Just say OK - what else can you do?

The SmartSync software will want to start automatically at boot-up. If you find that the software is incompatible with any of your other USB devices, then click on SmartSync's tray icon and select "Settings" and tell it not to start automatically. Then reboot, and your other device might be fine until you run SmartSync again.


b-splines

I've posted a ruby implementation of b-splines, along with an explanation of how b-splines are calculated.
