The power adapter included with the device appears to be a JODEN JOD-SBU050242 (100-240VAC ~ 50/60Hz, 0.45A max. -> 5VDC 2.3A).
SOURCE: Connecting the camera via USB hub.
Use of a USB hub for connection does not guarantee normal operation. Try attaching the USB cable directly from the D-snap SD Camera to one of the built-in USB ports on the PC.

The printer is the problem, obviously but, also try using a different USB cable to see if that doesn't help! When plugging up th cable, look for anything out of the ordinary! If changing the USB cable doesn't resolve the situation then it could be something shorted out in your printer and you need to take it to a service shop for repair! regards, babb

Hi there. This message would indicate any one of the following: 1. You have a lot of USB devices plugged in to your computer, and the maximum power supply for the USB ports has been exceeded by plugging this player to your computer. It would be best if you unplugged 1 or 2 of the USB devices connected for the time being. 2. You are plugging the player on your front USB port, and may need to plug it in the rear USB port to acquire ample power supply (front USB ports do not get as much power as the rear USB port -- sad but true) 3. You are using a laptop and may need to try another USB port on that computer. Purchasing a self-powered USB hub would be ideal as it gets its power supply directly from the wall electrical socket.

Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

WinXP SP2 blocks the use of the drive because it thinks it draws too
much power. But there is a simple procedure to override this (from WD
site):
"Problem:
Under Windows XP, an error message of "Power Surge on Hub Port" or
"USB device has exceeded the power limits of it's hub port" is
displayed when connecting a USB device to a USB port on a computer or
Hub.
Cause:
Under some computers, USB devices are only allowed to draw a
maximum of 500 milliamps (mA) per connection from the USB port on the
computer system or from a USB hub. Under the Windows XP Operating
System, with the release of Service Pack 2, if a device attempts to
draw more than this (500 milliamps), a USB port balloon message is
displayed to indicate this over current condition. When connecting a
USB device that draws power from the USB bus, a very brief over current
condition is sometimes detected by the OS, and the warning message is
displayed.
Resolution:
This message has no affect on the functionality of the USB port.
The USB hard drive should still function correctly on the USB port
regardless of the error message. To prevent the USB Power Surge Alert
message from displaying, please complete the following steps:
Click on Start.
Click on Control Panel.
Double-click on the System Icon.
Click on the Hardware Tab.
Click on the Device Manager button.
Click on the + next to Universal Serial Bus Controllers to expand the selection.
Right-click and select Properties on any listing that displays USB UNIVERSAL HOST CONTROLLER.
Click on the Advanced Tab.
Check the box that says: Don't tell me about USB errors."
This works fine, and the drive works fine afterwards. I suspect it
actually draws less power than they say. Maybe it has a brief power
draw spike on startup, but it's running power seems less. In any case,
it works fine without the Y cable. I do think it is tacky that WD
doesn't give the cable for free, since my $7 Sabrent 2.5" Hard drive
enclosure came with a y cable.
But most likely the drive will work fine for you. It is a lovely quiet drive, and takes up no space at all.
