I fitted a Pluscom U5P-VT6212L 5 port USB2.0 high speed adapter (PCI). It works, but only at USB1 speed. When I plug my Hitachi USB 2.0 external HDD into this adapter I get a message saying that this device can perform faster if plugged into a USB 2.0 port.
Also, there is no difference in performance if I plug the external HDD into the original USB1 port on my system.
My OS is WindowsXP SP3 and the PC is built on an ECS K7S5A Ver1.0 motherboard (SiS 735 chipset).
Is it possible to get this adapter to work properly with this system?
