Could you please tell me how to install USB connection in my computer (which is rather old). Thanks:confused:

If the rather old computer has PCI slots, then you can simply buy a PCI USB adapter. Ensure the adapter you buy is compatible with the OS you are using, which at minimum is Windows 95 OSR2 which has USB support.

Assuming you are using at least Windows 95 with USB support, Install the software first, then shutdown the PC. Install the adapter, then reboot and the OS should pick up the drivers automatically.

If not, follow the instructions that came with the PCI USB adapter card.
