A method and system for using a peripheral device identifier obtained from a peripheral device to determine a network address from a database, or generate the network address based on the identifier. Information related to the peripheral device is obtained from a remote device at the network address. The method includes automatically transferring at least one identifier from the peripheral device to a host device when the peripheral device is connected to the host device. The step of transferring is preferably done during or after enumeration of the peripheral device, such as occurs when a USB device is connected to a computer. The identifier is used as an index to automatically determine a network address from a database on the host device or a remote device, or to automatically generate a network address. Then, communication occurs between the host device and a remote device or other source of the information indicated by the network address. For example, the host device may download a device driver for the peripheral device from the remote device or from another peripheral device connected to the host device indicated by the network address.

The present invention describes techniques for performing flow control in Universal Serial Bus (USB). In one design, a USB host sends token packets to a USB device to initiate data exchanges with the USB device. The USB device determines that it is incapable of exchanging data with the USB host, e.g., because there is no data to send or because its buffer is full or near full. The USB device then sends a 'flow off' notification to the USB host to suspend data exchanges. The USB host receives the flow off notification and suspends sending token packets to the USB device. Thereafter, the USB device determines that it is capable of exchanging data with the USB host. The USB device then sends a 'flow on' notification to the USB host to resume data exchanges. The USB host receives the flow on notification and resumes sending token packets to the USB device.
