Looking for some memory stick drivers

I have an HP Pavilion F755US laptop that I installed Win 8.1 Pro on. Everything is working well except I have some yellow question marks by 2 Base System Devices and one Coprocessor. Haven't been able to find the drivers for them. Anyone got a good source. Thanks.

Base System
PCI\VEN_1180&DEV_0592&SUBSYS_30EA103C&REV_12
PCI\VEN_1180&DEV_0843&SUBSYS_30EA103C&REV_12
Coprocessor
PCI\VEN_10DE&DEV_0543&SUBSYS_30EA103C&REV_A2

have you installed your chipset drivers for 8.1? can you post a screenshot of what it shows in your device manger and not just your hardware ID's?

That's a legacy product, they no longer have a support page for it at HP.

I found this:

Hewlett Packard (HP) Compaq Presario F755LA Notebook PC, Compaq Presario F755US Notebook PC, Compaq Presario F756CA Notebook PC, Compaq Presario F756LA Notebook PC, Compaq Presario F756NR Notebook PC, HP Pavilion dv6620la, HP Pavilion dv6910us Free D

Someone pointed to these Windows 7 Drivers for a different model, might use the same card:

In either case you will have to extract the drivers from the installer using WinRAR and install them manually.

If all that fails, the only other thing I can suggest is buying one of those 4-in-1 card readers that can read your cards that plug into USB. Unfortunately your error message does not identify the card reader make, it should be Ricoh, you might find a driver on the Ricoh site if they have drivers.

I don't use DriverGuide anymore. They require a download installer for free downloads and those things just load up your system with a lot of crap like games and "mega deals".
