Realtek 3-in-1 MultiCard Reader
This is a USB device.
MMC / SD / SDHC
- works through the generic USB storage driver
- may work. Please confirm. Note however that larger then 32GB cards by default use the proprietary (patented) Microsoft exFAT filesystem which is not supported. The solution for such cards is to change filesystem, assuming that the devices the card is to be used with also support other filesystems.
