This is a nice product, easy to use and works as advertised. Can't ask for more.

This card has NEVER worked. I've messed with it on and off for a month now and am finally throwing it away. As soon as I plug in a thumb drive the computer crashes with a blue screen.

From my experience and looking at the other reviews, stay away from this junk. Don't throw away your money.

But it didn't work for me. Every time I plugged a device in to it, my laptop crashed with a "blue screen," and I had to wait for a reboot to use the device.

The device worked fine for two weeks then it made my laptop crash every time I had it inserted. Thank goodness removing the device brought me back. I spent hours trying the ideas from the Micro tech. Nothing helped. Its junk.

I was a bit worried after reading the negative reviews of this card but it works fine, and for the price <$30 I have no complaints - it does the job.

Noted behaviour:

Running under XP - it does not require the drivers that ship with it - seems to run fine with the XP default drivers or with the shipped (non-XP certified) drivers on CD.

Running a USB2 external disk (ION) that draws power from the USB port requires that you plug in the external power adapter for the card (it ships with it) to supply sufficient power for the device. If you don't plub in the adapter there are no warnings issued - the external drive just fails to be detected and configured, although all the ION power LEDs are on (if you listen closely you realise the disks aren't spinning). This may lead you to believe that the card and/or the external device is not working.

XP sometimes complains about power surges exceeding specs on the USB hub when you plug in the AC adpater or the external drive, but the USB managemnt spec seems resilient enough to detect and handle this - in other words, no hardware smoked. The caveat is that XP says "click here" to resolve the problem and it doesn't - XP appears to shut the port or ports down so you need eject the card and re-insert.
