Speed of USB Port

bb1668

I used HD Tune to check the data transfer rate when an external hard disk is connected to my laptop (through a craddle).  It is very slow around 10MB/s.  

However, when I conduct the same test for the internal hard disk of the laptop, it is much fast - around 45MB/s.

Since only external connection through USB is a problem, I suspect there is something wrong with the USB port.  How can I test if the USB port is 2.0 or just 1.0?  Further, how can I test if the USB driver is correct.

Many thanks in advance.

P.S.  I have checked the external hard disk and craddle and they are working fine with other computers at a speed of around 28MB/s

I have check the spec in the internet.  All the USB ports are 2.0.  Accordingly, I suspect it is a driver problem then.
