You say that the second one uses ftdi232. There are some issues with USB on
Raspberry. Look at this thread.

A quick solution could be adding  dwc_otg.speed=1 to /boo/cmdline.txt it  
will
switch usb to 1.1 only so the network speed will decrease significantly.
This helped with a usb wireless keyboard.

Also the newest kernels have better usb drivers but still not perfect.
