I bought a flash recently,
In the warranty card there was a caution saying "Always use USB ports on the back of the case" .
Is there any difference between front and back ports?
They are all connected to the MoBo the same way providing the same voltage, functionality etc?
Ny difference between front and back USB ports

I have had motherboards in the past that provided usb 1 on the headers (which connected to the front of the case), and provided usb 2 to the ones mounted/attached to the back of the board itself (aka the back ports).
This is purely a design choice made by the board designer(s).
With respect to your flash-memory stick, the manufacturer of that device is gambling on the idea that the ports on the back are going to be the highest supported standard at the time of the board's manufacture. Since they did not design your motherboard, they have no way of knowing for sure.
They need to make a statement for the people most likely to need the statement made. More technically minded individuals will probably know that the generalization made int he manual is too narrow. For the less technical, if they follow what is written, they are more likely to not have problems with the device.
Oversimplification is a common teaching tool, and one of the reasons that technical fields must re-teach certain subject at the college level to correct these errors or over-specifications in high school level classes.
