I'm running x64 Windows 8, and the SD card reader in my Dell M4600 is unable to read my SDHC memory card.

The reader is listed as "SDA Standard Compliant SD Host Controller" in device manager. I'm unable to find any drivers/firmware for the reader on the Dell website.

Is there any way to get this reader to read SDHC cards, or confirm that this is not possible?

Without the exact model of the reader we cannot help you. Its normally listed in the purchase invoice or some other documentation that came with your computer. Please provide this information. If you cannot find it then Dell can provide you information on the device. I am going to guess this reader only supports the SD format. There is a difference between the SD and SDHC(High Capacity) formats. – Ramhound Oct 4 '13 at 11:22
I am going to guess this reader only supports the SD format. It certainly looks like it. Supposedly sometimes a firmware or driver upgrade can add support, but it appears not in this case. – mackenir Oct 4 '13 at 16:08

Well, there is a driver for M4600 card reader available for download from Dell website.

Try O2Micro OZ600xxx Memory Card Reader Driver for Win 8 x64

Thanks - I gave that a try and it appears that I already had that installed, so sadly I saw no improvement. – mackenir Oct 4 '13 at 16:08
@NikolaD - How on earth did you find the brand and model. Every document I read on this laptop literally only called it a card reader. I am also including the full specification datasheet :$ – Ramhound Oct 4 '13 at 16:11
Device ID should be 0x8231 – Nikola Dimitrijevic Oct 4 '13 at 17:05
