There is no such concept as a USB port.
USB is a bus so you address devices.

Is your device a HID device (Human InterFace Device) like mouse or keyboard?
If so then i have a HID component which i can send you.
Please contact me directly robert_marquardt@gmx.de

Non-HID USB devices have no API of their own. They are accessed by the standard file API CreateFile ReadFile WriteFile etc.
Some devices like mouse and keyboard are also accessed through DirectInput.
Access to webcams is normally through TWAIN.
