I doubt a driver update will help. You need a reader capable of SDHC. Look at the Wiki link below.

I understood what you need. Memory stick or SD card is the same issue. The reader must be capable of reading the higher density media.

Your product has been discontinued. That means there will most likely no further updates for it. Below are three links that might prove helpful. The first is to the Sony site, which can scan your Vaio.

If I format card for data use it is fine, sstem reads as it should.

If I try to use as memorybooster, sometimes it does ok and reserves 7.xx gb which is good! other times dependind mood of computer :) it says cannot do

If I plug into card reader and axcess computer thru USB port, works fine... (but excuse the expression like something is dangling from computer (dingleberry...haha) and not very safe if in transit.

Also Sony unless I know model same drivers as my VGN-S260 will not tell me which will work. and if it too new from my system will say not for this application, and drop the ball. Unless there is a way to tell site to ignore I just want software driver.

If you have ever gone to T.I. about embedded software... so hidden and hard to axcess. Try to find driver for my system...

The reason you can't find the software/drivers on the Texas Instruments site is because they sell the hardware and a generic driver. In your case, Sony had to customize the drivers to work with the configuration they have.

Hardware is usually designed to perform more functions than may come with the finished product. In some cases it is just a matter of someone not willing to pay a fee to use a feature.

None of that matters anyway. I don't think you will ever get that reader to work with 8GB or larger media. This is no different than a motherboard designed to use certain density RAM and then the RAM densities increase. The old controllers can't handle the higher density because the weren't designed to.

A driver probably wouldn't fix that. Possibly a firmware update would but I couldn't find one. Sony is not a company to worry about compatibility.
