Cameras, Memory Card Readers and Non-Functioning Plug&Play with Assorted Things

[The_Mark]

Rright. Just getting a bit pissed off at my Windows.

Now, this is what should happen: I plug my Powershot G5 camera/Kingston memory card reader to my computer via a USB cable, plug&play connects and I transfer pictures from the camera/card reader to my hard drive.

What happens is as follows: Windows recognizes the device I connect to it without any problems, but requires drivers to be installed. When installing the drivers (which shouldn't even be necessary), regardless of which ones I choose, be they the standard Windows stock or new manufacturer drivers, I get an error message: "Incompatible data" (or something to that effect, got a Finnish version of Windows). Then the device appears in the device manager (or whatever) tree in its proper place but with that pesky little black exclamation mark on yellow background on it. Doesn't work.

So, What The Hell?

When USB devices are about to fail completely, I come across with such problems. I can't say it's beyond anything possible to work out though. I just don't have an idea.

It's not about the devices; they work perfectly with other computers.

Assuming that the computer in question is has XP, is it SP2?

[The_Mark]

Yes.

Have you tried different USB ports?
My dad has some USB ports on his USB hub which just won't work correctly.
Did you install all other drivers, like mainboard drivers, including USB 2.0 drivers(yes, they are usually seperate)?
Did you try disconnecting the device, kicking all drivers out, restarting, then installing drivers from disc and then reconnecting the device?
That's all I can think of for now, generally installing drivers when Windows asks for it is not recommended by me, always abort and use the driver installer if there is one. If there is none, ok, follow Windows.
