I re-installed Windows 7 and I currently have 2 Base System Devices with a yellow exclamation which means it's unrecognized and the drivers for it are missing.

Windows update has been unable to find the missing drivers for the device and I can't figure out what the device could be.

I have a Dell Inspiron 1525. What could the Base System Device be?


Here is a screenshot of the same

the Ricoh driver usually installs 3 devices, extract the Dell Vista driver (e.g. with Universal Extractor) and look for the following subdirectories and install the driver manually via the device manager:

xd, sd and smc

worked for me on an Inspiron 1525 with Windows 7 32-bit yesterday.

Change the view to View by Connection, and then see what it's connected to. That should help determine which devices these are.

I would guess they're SD media controller or something like that.

Did you update your chipset?

updated the post above and it doesn't seem to be the SD media controller as that already exists –  rzlines Dec 23 '09 at 5:58
    
try installing the Ricoh chipset & the mobile chipset again. I had almost this exact same issue, with the two unidentified base system devices, and it was fixed with the chipset update. –  Nathan DeWitt Dec 23 '09 at 17:02

I also have a 1525 and the only drivers I felt I needed to install were for sound and for touchpad. Everything else is quite fine with the W7 built in/findable software. While my system also shows the same yellow (not red for complete failure) notifications, basically if it isn't a problem, then don't worry about it. Have you had any hardware difficulties? I find this an essential attitude with Windows OSs, although not really a SuperUser approach...

Base System device : it is SD memory. If you install SD Memory You will be resolved your problems

not really I had to merely target the right drivers to solve this problem. True it had to do with the card reader on my laptop, but as I am currently using Windows-7 the Vista drivers have to be installed manually sometimes –  rzlines Sep 27 '10 at 20:32
