USB TO SD ADAPTER NOT TO PLUG SD CARDS INTO A COMPUTER BUT TO PLUG USBS INTO A SD CARD SLOT ON PORTABLE DEVICES?

BASICALLY I HAVE SEEN ADAPTERS THAT ALLOW YOU TO PLUG SD CARDS INTO A USB PORT ON A COMPUTER. WHAT I WANT IS TO BE ABLE TO PLUG A USB INTO AN ADAPTER AND THEN INTO A PSP MEMORY STICK SLOT   YOU MAY BE ASKING WHY

FOR STARTERS USBS ARE A LOT CHEAPER THAN SD MICROS AND SUPER EASY TO FIND I COULD GET A 18GB USB FOR LIKE 20 BUCKS BUT IT WOULD COST CLOSER TO A HUNDRED FOR A SD MICRO

ARE THERE ANY WAYS TO MAKE SUCH AN ADAPTER OF MAGICAL WONDER ?!?!?!?!?!

he means one that can plug into a device (one end is micro sd shaped) and the other plugs into a computer so you can transfer files without having to plug the micro sd in and out of the computer and you can transfer files without taking out the card

By "a USB" I presume you mean a memory key ("thumb drive") which plugs into a USB port, right?

If you can do it, you'd need a microcontroller in the middle to take the commands coming into the SD card and remap them to USB commands, which the memory key would then translate back into memory addressing operations.

Conceptually, possible. But I'm not sure you'd be able to get fast enough response through all those layers to meet the SD interface's specs.
