several microSD? Doubt it, but an SD or microSD card usb adapter will function exactly like a USB stick if it's formatted in FAT (in terms of being able to use it like a thumb drive in other devices like, erm, a PS2 for example, or pretty much anything else i've tried it in). Considering when i put more than one device in my 6in1 card reader, that they all show up as seperate devices, it's unlikely that there could be some sort of apparatus taht would let you put in several cards and have them show up as one big card.
