Have installed a PCI USB 2.0 card in my G5 running Tiger.

On the G5 ports I have a flash card reader and my Cinema Display and on the USB 2.0 card ports I have 2 Printers, iPod Shuffle Dock, & Canon Scanner.

On startup usually my scanner is not detected for some reason although unplugging it then connecting again usually gets it working.

If I connect the scanner to the G5 ports the scanner works but more often than not my mouse/keyboard which are connected to my cinema display then don't work.

Is it possible i'm trying to power too many devices?

I would try unplugging a few devices and see if you problems go away. I suspect too many peripherals pulling too much power.

This is possible

Have now rejigged the arangement:

G5 is Card Reader and Monitor which has Keyboard/Mouse Connected - This all works fine.

On the USB Card I now have 2 x printers neither of which are turned on at startup and my iPod dock which has no iPod connected and also my Canon Scanner which in theory is now the only device needing power.

I would say however that at least half the time my machine won't recognise the Scanner on startup - maybe it's just a dodgy scanner over USB. Might have to buy another...
