MS Card slot
The MS Card slot (Sony MemoryStick) is found on select Docking stations.
In addition to the original MemoryStick Cards, this slot also supports the newer MemoryStick Pro, and the MemoryStick Duo variations (with the Memory Stick Duo Adapter).
Linux support
NOTE!
There is no support for Copy Protected MemorySticks in Linux, which are luckily extremely rare
USB based readers should be supported by the Linux USB Storage drivers (usb-storage).
PCI based readers are more problematic as they require two pieces. Generic Sony MemoryStick support in the kernel, which the latest kernels have through the memstick driver, and a so called 'host' interface driver. This later one is often missing for common chipsets like Ricoh.
