Base System Device Problem - Vaio VGC-JS160J

I recently reinstalled Windows Vista Home Premium x64 on my computer (Sony Vaio VGC-JS160J).


I have downloaded the needed drivers, but I can't seem to find what "Base System Device" is. It still has the yellow exclamation point symbol.


I have already downloaded the Ricoh SD/MMC Memory Card Driver, and it did not fix this problem.


The only information I have on it is:


Location: PCI bus 2, device 3, function 2


Hardware lds:
pci\ven_1180&dev_0592&SUBSYS_9044104d&rev_12
pci\ven_1180&dev_0592&SUBSYS_9044104D
pci\ven_1180&dev_0592&CC_088000
pci\ven_1180&dev_0592&CC_0880

Someone please help me... It's driving me insane.

-Also, on a side note: can someone tell me if I should wait until Windows Update lets me install Service Pack 2, or is it okay to manually upgrade?

Please someone help me resolve this issue... I've posted a thread about this on 3 different sites, and so far I have not found any answers.

I still have the "base system device" issue, and am wondering if anyone--ANYONE--can tell me if it'd be okay if I upgrade to Vista Service Pack 2, with this issue not fixed?
