Abstract

A method for transceiving non-USB peripheral device by an adapter and the adapter providing adaptation to an USB interface for the non-USB peripheral device, is disclosed. The adapter can read a capability report from the peripheral device and then converts the capability report to an USB-related report for facilitating accessing of the peripheral device. The adapter utilizes control commands and parameter set pre-defined by the adapter and the peripheral device to successfully access the peripheral device. The peripheral device has vendor identification (VID) and product identification (PID) and the controller transceives or detects the peripheral device with reference to the information of VID and PID.

Claims

1. A method for transceiving between a peripheral device with a non-USB interface and a computer with a USB interface by using an adapter, the peripheral device being coupled to a computer through the adapter, the adapter providing adaptation to the USB interface for the non-USB interface, the method comprising the following steps of:

sending a control command to the peripheral device by the adapter;

receiving the control command from the adapter by the peripheral device;

sending a related information to the adapter in response to the control command by the peripheral device;

receiving a parameter from the peripheral device by the adapter; and

converting the parameter into a USB-related capability report and sending the USB-related capability report to the computer by the adapter.

2. The method for transceiving between a peripheral device with non-USB interface and a computer with a USB interface as in claim 1, wherein:

the non-USB interface is a PS/2 interface.

3. The method for transceiving between a peripheral device with a non-USB interface and a computer with a USB interface as in claim 1, the peripheral device further comprising a peripheral memory;

and the peripheral memory has a data bank for storing related information for the USB-related capability report.

4. The method for transceiving between a peripheral device with a non-USB interface and a computer with a USB interface as in claim 1, the adapter further comprising a controller and an adaptation memory, the adaptation memory having a data bank for storing vendor identification (VID) and product identification (PID) of the peripheral device, and the controller detects the peripheral device with reference to the information of VID and PID.

5. The method for transceiving between a peripheral device with a non-USB interface and a computer with a USB interface as in claim 1, wherein the control command and the parameter are pre-defined by the adapter and the peripheral device.

6. A peripheral apparatus used with an adapter, comprising

a peripheral device with a non-USB interface having a peripheral memory with a data bank;

an adapter coupled to the peripheral device and for providing adaptation to an USB interface for the non-USB interface, the adapter comprising a controller and an adaptation memory having a message data bank.

7. The peripheral as in claim 6, wherein the non-USB interface is a PS/2 interface.

8. The peripheral as in claim 6, wherein the data bank of the peripheral device stores related information for an USB-related capability report.

9. The peripheral as in claim 6, wherein the message data bank stores vendor identification (VID) and product identification (PID) of the peripheral, and the controller detects the peripheral with reference to the information of VID and PID.

10. The peripheral as in claim 6, wherein the adapter utilizes control commands and parameter set pre-defined by the adapter and the peripheral device to successfully access the peripheral device.

11. The peripheral as in claim 6, wherein the USB interface is selected from the group consisted of USB 1.0, USB 1.1 interface and USB 2.0 interface.
