Do you have motherboard diagram? If yes, see if the front bus is 2.0 compliant.
If not, Open Device Manager, under USB Controllers you should see one of the entries say Enhanced Host Controller if you have USB 2.0.

Thats the SS of my Device manager.... Enhanced is there.. but for the rear or front cant say.....
Since you are having Dual core ( not very old ) system, mostly all your ports will be 2.0.
The front ports are connected to the Motherboard through wires which may sometimes pick up noises. The rear ports are directly soldered on the Motherboard itself.
For data cards always advisable to use rear port, to avoid the doubt but with a Ferrite filtered USB cable. It enables the data card, to place at a convenient place and more importantly orientation may be adjusted towards tower, to get better signal strength. These are not possible, if you connect the card directly to the port.
So the question of against the wall solved.
i am also thinking of getting USB extension cable in case i dont get good speed... btw any idea how much one can cost... i saw some at
ebay costing arnd 120 bucks.. are they good enough??
by the way another query was that i am currently on Dataone 750 UL ... and i had paid advance rental.. so its upto june.... so any process by which i can combine the speeds of the Datacard and the Dataone connection without using any Hub/
Router...?? is it possible by any S/W may be....
