i have w300i and vista and there work good together just go to sony ericsson web site and download software off there website and download the update software and it works with the cable

I would have to agree on that one that Vista does suck in that area among others.

Unfortunately this is yet another reason why there is no intelligent reason to use Windows Vista.

if you have a photo printer, that can opt as another card reader assuming you the adapter that take the m2 card and also the photo printer has the card reader built-in

Well, at least you know that there's nothing wrong with your PC or M2 card. Perhaps you can get a refund or replacement for the defective card reader. However, maybe next time it would be safer to stick with a known brand. I always use SanDisk, and that has never let me down.

If the other cards work, try reinserting the M2 card a couple of times.
Or try using the card reader on another person's PC, like greenblood stated.
Like greenblood pointed out, it might be a defective card reader, IDK.

I think it might be toast. I won't read my SD card from my camera either. That really sucks. Thanks for all your help everyone!

good luck

Under USB controllers I have the following.....
USB Root Hub
USB composite device
Standard Open HCD USB host controller
Standard Enhanced PCI to USB host controller
I checked them all and they said they were working correctly and drivers were up to date.
Unfortunately my card reader is built into the computer so using a machine with XP is out of the question.

I don't think Vista needs extra driver for your card reader
do you have XP machine? try it
if the reader still doesn't show up, it's dead

No, I don't have an Xp machine, I wish I still did. This computer's about a month old, so I hope the reader's not broken. When I went to the device manager there was a lot of jargon I had no idea what was what. There was nothing that looked like a card reader though. I appreciate your help.

When I look on the outside it says Smartmedia.... is that right, or do I check somewhere else? Sorry, I'm a noob to this.
My computer is an Acer Aspire E380 Running Windows Vista.
Thanks for the help. I really appreciate it!

Hmmm... no I didn't install a driver. I did however do an online search to see if I could find one, but I didn't find anything. You're correct, it is a 9 in 1 card reader. It won't recognize my SD card either. thanks for the advice, I'll keep looking.
