update the Teac CA-200 all in one Card Reader to read microSDHC 4 gig card. The all in one reader was made by Teak specifically for dell. This driver was found on the dell site and it DID install on my non-dell system.*miracles huh?* Mine is a home made system with an ASUS mobo and windows xp. It was reading all cards fine until I bought a new SDHC 4 gig. Now it reads those too. It will probably read an 8 gig too. Specifications PDF is included in this file telling you what upgrades it does and what O/s are Okay and what Dell PCS had them.
