a strange one this.

I have a 6 in 1 card reader (USB 2) which has been happily running off a USB 1 hub. (slow, but it works)

I recently bought a USB 2 hub. However, when I plug the card reader into the USB2 hub I get a "USB device not recognized" alert, and the hardware manager shows an "unknown device" error. I have used windows magnificent troubleshooter to no avail (honestly - its like throwing a drowning person both ends of a piece of rope)

At the moment I have both hubs plugged in, and the card reader is running quite happily off the USB 1 hub. It doesn't need drivers. When I unplug the card reader from the USN 1 hub and plug it into the USB2 hub I get the warnings. When I unplug from the USB 2 hub and replug it into the USB 1 hub I get the "this device can operate faster" blurb, and it shows the USB2 hub as being available...........

I know the USB 2 hub is working, as I have plugged flash drives into it. I would like not to have 2 USB hubs running and for the card reader to run at full spead (the odd 1/2 seconds are important!!)

Am I missing something really basic?

Since I don't know all of the specs I would check 1) Does the reader need a powered port\hub to function? 2) Is it possible the USB 1 is a powered hub and the USB 2 hub is not? Have you tried by passing both hubs and connection straight to the computer? Have you considered a 5 port (4 external\1 internal. USB addon PCI USB 2.0 card? $15 -+ on eBay.

It's wierder than that: the USB 1 hub (which works with the reader) is unpowered.
The USB2 hub (which doesn't) is powered.

The USB hub works with everything except the reader. I wouldnt mind so much - but getting the "this device could function fast" (on the USB1 hub) warning pointing me to the USB2 hub which then doesnt actually recognise the reader does my head in.........

I dont actually care that much........ except it shouldn't be so. :thumbsup:

Are all your Windows updates installed? There maybe a patch laying around out there. Have you checked the reader's web site for known issues?

as ever - the reader is generic........... no makers mark etc. surely a card reader is just a card reader.....XP has USB support, so I shouldnt need drivers (thats the way I read it,,,,,,,,,am I wrong?)

Sp2 is installed, Im all up to date

It's just wierd........and frustrating. I'll manage to live with it, even though it does make no sense. Having bought a new hub Im not really excited about the thought of buying a new USB card..........

No you are 100% right. With XP it should be plug 'n play.

Sp2 is installed, Im all up to date

That should do it.

I know not a good choice. Just stating the obvious. Sorry.
