No, it depends on the real requirement of your AX88772A target application. If your end customer may need to install more than one AX88772A-based device on your target application, you should assign a different serial number in the EEPROM for every AX88772A device. If your target application always uses one AX88772A device, you can consider assigning the same serial number in the EEPROM for every AX88772A device for easy maintenance in mass production, especially if you plan to use a Windows PC to test AX88772A based devices repeatedly during the mass production test.

It depends on your product applications and target market which may vary case by case. Below are some general guidelines on whether one can use ASIX's VID/PID or use its own registered VID/PID. 1. Case where it is OK to use ASIX Electronics's VID (0B95h) and PID (772Ah): (1) Your AX88772A-based application works with the standard AX88772A drivers provided by ASIX without any modification to the driver. (2) You are not concerned from a business and product marketing perspective about sharing the same VID and PID on your products as ASIX's other customers. (*Note) Please inform ASIX by emailing us at sales@asix.com.tw beforehand if you would like to use ASIX Electronics VID and PID for your products. *Note: This can avoid your end customers from downloading the standard AX88772A driver from the ASIX website which may not be compatible with your device drivers. 2. Cases requiring you to use your own VID and PID (1) Your AX88772A based application system doesn't work with the AX88772A standard drivers released on this website and your target application system (such as USB dongle or docking station) allows end customers to update the standalone AX88772A driver by themselves after sales. In this case, you MUST assign your own unique VID and PID to your AX88772A based devices. (2) For brand name products, you probably don't want your AX88772A-based devices to be compatible with other companies' AX88772A-based devices. In this case, you should consider assigning your own unique VID and PID for your AX88772A based devices. You can register your own VID from USB Implementers Forum, Inc. and define the PID based on your company rules. If you have any problems, please contact ASIX's sales (sales@asix.com.twa>) for further support.

The answers to above questions really depend on user's product applications and target market, which can be different on individual cases. Below gives customers some general guidelines about whether one can use ASIX's VID/PID or one should better register its own one with USB-IF. 1.Case where it is OK to use ASIX Electronics's VID (0B95h) and PID (772Bh): You may be able to use ASIX Electronics' VID and PID when your AX88772B based application system can simply work with AX88772B standard drivers provided by ASIX without any modification and you don't have any concern from business and product marketing perspective to use the same VID and PID on your products as ASIX's other customers who are also using ASIX's VID and PID. ASIX Electronics would like to request customers to inform ASIX sales staffs by sending us email at sales@asix.com.tw beforehand if you would like to use ASIX Electronics VID and PID for your products. In other words, if your AX88772B based application system requires you to modify AX88772B driver on your own or by ASIX support team, you might have to register your own VID and PID. This can avoid your end customers from going to ASIX web site to download the AX88772B standard driver which may not be suitable to work with the specific AX88772B based application system. 2.Cases requiring you to use your own VID and PID (1) Your AX88772B based application systems can't work directly with AX88772B standard drivers which ASIX Electronics release on its web site and your target application system (such as USB dongle or docking station) may allow your end customers to update the standalone AX88772B driver by themselves after sales. In that case, you MUST assign your own unique VID and PID for your AX88772B based devices. (2) For brand name products, you probably don't want your AX88772B based devices to become compatible with other company's AX88772B based devices. In this case, you should consider assigning your own unique VID and PID for your AX88772B based devices. You can register your own VID from USB Implementers Forum, Inc. and define the PID based on your company rules.

The answer depends on whether the USB host controller supports the S4/S5 wake-up function or not since the WOL function of AX88772A USB to LAN devices should be supported on both AX88772A and the USB host controller. Many USB host controllers don't support the WOL function in S4 (Hibernate)/S5 (Shutdown) mode.

AX88772A supports some default settings inside chip hardware to enable it to communicate with USB host controller during enumeration when the AX88772A EEPROM is blank (prior to being programmed). The default settings inside chip facilitate users to update the EEPROM content through a Windows PC during R&D validation process or program a blank EEPROM mounted on target system PCB during manufacturing process. ASIX Electronics provides a Windows SROM Programming tool for users to easily program the Serial EEPROM of AX88772A on a typical Windows XP/2000 PC. This AX88772A WinXP/2K SROM Programming Tool supports to customize the MAC address, Serial Number, Vendor ID and Product ID, etc. for AX88772A based application systems in mass production. Alternatively, users can pre-program the blank EEPROM on a 3rd Party Universal Programmer before soldering the EEPROM onto the AX88772A application device. It is recommended that users assign a unique MAC address in the EEPROM for every AX88772A device. Also if users plan to use a Windows PC to test AX88772A-based devices repeatedly during mass production, it is recommended that the same serial number be assigned to the EEPROM for every AX88772A device. However, a different serial number should be assigned in the EEPROM for every AX88772A device if users need to install more than one AX88772A device on the same platform. Please contact ASIX's sales (sales@asix.com.tw) to get the AX88x72A EEPROM User Guide for more details.

AX88772B supports some default settings inside chip hardware to enable it to communicate with USB host controller during enumeration when the AX88772B EEPROM is blank (prior to being programmed).
