Toshiba SD Card reader driver?

Hi,

Look on the bottom of the computer for model information.
Also Start - type in Search box -> System Information.

---------------------------------------------------------------------------------------------------------------

Since the system originally had another version of Windows did you run the Upgrade Advisor and
check the Compatibility Center for the SD Drive (and other devices as needed).

Windows 7 Upgrade Advisor - please run this now.

Also check the Compatibility Center (for major devices)
http://www.microsoft.com/windows/compatibility/windows-7/en-us/default.aspx

Check with the System maker (Motherboard Maker for custom built systems) and the Device maker
for information about drivers for Windows 7. (BIOS, low level chipset drivers, and other major device
drivers). Toshiba does have a lot of help for upgrading most models on their website, check for your
model.

Check with Toshiba Support, their on-line drivers (to update or re-install), and their forums.

Then lets refresh the USB Stack

Control Panel - Device Manager - click anywhere in the blank/white area - then VIEW -
Show Hidden Devices

Now look everywhere EXCEPT USB Controllers for your device and if you find them (may have
more than one of each) under Disk Drives you may have several - RIGHT CLICK and UNINSTALL 
for all instances.

Control Panel - Device Manager - USB Serial Controllers - RIGHT CLICK on EVERYTHING and
UNINSTALL all except the category itself - REBOOT - this refreshes the drive and the USB stack

Here is a utility to help but do the above 1st.

USBDeview is a small utility that lists all USB devices that currently connected to your computer,
as well as all USB devices that you previously used. Run it Options and check the 1st three choices
to see if any are there.
