There is no such concept as a USB port.
USB is a full serial master slave bus not a serial line like RS232.
You always talk to USB devices. Talking to the USB port is as silly as talking to your ethernet cable.
There is not much API to access for USB.
Most USB devices are accessed through other APIs without any USB specifics at all.
A USB stick for example is a removable harddisk.
To access HID devices (joysticks etc, a subclass of USB devices) you can use my free Delphi HID component available at

Can we go a bit deeper into this, I realise that you cannot simply talk to a cable.
We have been asked by an existing coustmer to add a USB(and Irda maybee Firewire) interface to his product. we have looked briefly at the Texas TUSB3410 interface chip. Texas tell us that this chip is recognised by Windows as a USB device, fine, but how do we then talk to it, e.g implement the existing serial data stream. ? Will we have to write a low level driver specificaly for the product or will Windows give access to registers within the chip, if so how, if there are no API's

This might be of interest to others, I dug around on the web and came up with a Driver creation utility for USB and other buses. 'Windriver' by Jungo, and it interfaces with VB, CBuilder and Delphi.
Delphi examples are included.
The version I downloaded is quoted as being able to talk to the Texas USB3410 Chip.
The 30 day evaluation period should at least give us time to work out what is involved.
