The problem is not the usb port but whether the kernel negotiates with the
device properly. Try to first connect the reader without the card and then do
immediately cat /proc/bus/usb/devices (lsusb should work also). If the device is
negotiated with properly, this should return rather quickly and show the
existing usb ports and the plugged in device. If this locks up for 10-20
seconds and then doesn't show the device then linux is doing something that the
device doesn't like. This may be solved by later/earlier kernels, but can also
be handled by a different card reader. Once this returns, recognizing the
device or not, run dmesg | tail -n 40. You should see messages telling about
what went on. If you post the output for both of these we could probably help
more.
If the device is recognized properly, then it may just be an issue of mounting
the right thing (these cards are sometimes formatted in different ways in term
of file systems and partitions).
