Have you tried the devices in more than one computer?

The subclass is the industry standard protocol transported by a mass storage class interface. In ln laymans terms i believe its the way the host determines the device type. It maybe the your computer is not reconising the device or that the device itselft is at fault. Have you tried another USB device?

I have tried three different USB sticks on my PC and they all work fine. It is for my 2010 Mercedes-Benz C-Series Car that I want it to work. I know the devices are not at fault because they all work on PC. The Car manual states that it supports USB sticks of a subclass 6 category only. Is this a brand new standard or older?

If i go and buy a brand new usb stick do you think it will be subclass 6?

It says it must be FAT formatted. I think it may be NTFS so that could be a likely possibility as to why it is not working.

Any common Flash Drive should work. Try a cheat 2GB Kingston first to see what happens but it should be 100% compatable. First format it in FAT in your PC and load some media in there. Or try one of your sticks but FAT formatted.

If it doesn't work, try and load a song in 92 kbps, another in 128 kbps and another in 256 kbps. I've seen some car sound systems that do not handle well all kinds of bit rates.

I DONT THINK IT WOULD BE THIS IN MY SITUATION AS IT DOESNT EVEN RECOGNIZE THE USB STICK AS OPPOSED TO NOT BEING ABLE TO PLAY MP3S

YES I WILL TRY THIS, MY MONEY IS ON THIS AS BEING THE PROBLEM.
