another usb problem

[efiste2]

i have just bought another card reader for my pc as the message when i inserted my other one read as follows "a usb device has malfunctioned and windows cannot recognise it". so i bought a new one, and ive just plugged the new one in and i get the same message, ive installed the software ok but it just wont recognise it and the device manager says no drivers installed, any ideas ANYONE, this usb problem driving me mad!!!

If you downloaded the software and drivers...goto the Device Manager,highlight the Device you wish to update,click Update Drivers,and point to the folder where the software was downloaded too.See if it loads the drivers.

I know it looks like it's your machine, but can you check the USB devices on another machine just in case?

You said ANOTHER...is this a 2nd reader or just an upgrade?
Was the old card reader completly un-installed,including drivers?
Did you install the Software for new reader first?

i have a usb swlf powered hub with a scanner and a b/band modem in it. i have had a problem with a second scanner not installing and thats still going on, and now the card reader problem, the origanal scanner and the modem work fine. when i use the device manager it says no drivers installed for the unkown device(new card reader) so when i try to reisntall using the cd that came with the reader it installs that fast i cant see the destination of the drivers ?????? im going in circles all the time, also my windows update is spot on so i must have the USB updates loaded in!! any ideas

windows update doesn't include driver updates.. for that, you need drivers from your motherboard manufacturer.. this could be the problem.. OR... if the hub you have is a self powered hub.. i.e. it doesn't have a plug to connect to a power socket at the wall.. then it may be that you are loading too many devices to it..

try each device one at a time.. and update your motherboard drivers.

if you're running XP, you can try this :
START-Control Panel-System-Hardware-Device Manager
Select view and click on display hidden devices. Uninstall all usb devices.
Now reboot and install all USB devices properly
