|A0010: ||ASIX Electronics provides a few options for programming the AX88178 EEPROM. Please contact ASIX Sales (firstname.lastname@example.org) to get the AX88178 EEPROM User Guide for more details.|
1. Windows SROM Programming Tool
The Windows SROM Programming tool supports modification of the MAC address, Serial Number and Vendor/Product IDs fields on a typical WinXP/2K PC.
Note: The Windows SROM Programming tool doesn't support programming a blank EEPROM. User needs to pre-program a default SROM data into AX88178 EEPROM before using Windows SROM Programming Tool. To do so, ASIX provides a Linux SROM Programming Tool solution (see below).
2. DOS SROM Programming Tool
The DOS SROM Programming tool supports programming a blank EEPROM in a MS-DOS environment; ASIX provides three DOS SROM Programming utilities (WS.EXE, HUBWS.EXE and HUB2WS.EXE) to program the AX88178 EEPROM, depending on USB port connection scenarios.
WS.EXE DOS SROM Programming Utility without USB hub
HUBWS.EXE DOS SROM Programming Utility for One-USB-Hub
HUB2WS.EXE DOS SROM Programming Utility for Two-USB-Hubs
Note: The DOS SROM Programming utilities need to initialize the USB host controllers directly and were qualified on some USB host controllers like VIA 6121, NEC D720101, etc. These utilities may not work with other USB host controllers. If you cannot find a workable PC to run these utilities, you can consider using other SROM programming solutions in mass production.
3. Linux SROM Programming Tool
The Linux SROM Programming tool supports programming a blank EEPROM on a Linux PC. ASIX can provide a Linux SROM Programming Tool Bootable CD upon request. The CD, with minimum effort, allows user to boot the PC directly to a Linux environment and then run the Linux SROM Programming Tool directly to pre-program a default SROM data into a blank AX88178 EEPROM.
Note: The Linux SROM Programming tool is primarily used to pre-program a default SROM data into a blank AX88178 EEPROM so that users can then run the Windows SROM Programming tool and the Windows Production Test tool in mass production.
4. 3rd Party Universal Programmer
Alternatively, you can pre-program the blank EEPROM on a 3rd Party Universal Programmer before soldering the EEPROM onto the AX88178 application device. It is recommended that users assign a unique MAC address in the EEPROM for every AX88178 device.
Also if you plan to use a Windows PC to test AX88178-based devices repeatedly during mass production, it is recommended that the same serial number be assigned to the EEPROM for every AX88178 device. However, a different serial number should be assigned in the EEPROM for every AX88178 device if you need to install more than one AX88178 device on the same platform.
|Q0011: ||Do we need to register our own VID/PID for our AX88178 based application systems or can we use the ASIX's VID/PID?|
|A0011: ||It depends on your product applications and target market. Below are some general guidelines on whether one can use ASIX's VID/PID or use its own registered VID/PID.|
1. Cases where it is OK to use ASIX Electronics's VID (0B95h) and PID (1780h):
(1) Your AX88178-based application works with the standard AX88178 drivers provided by ASIX without any modification to the driver*. 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.
Please inform ASIX by emailing us at email@example.com beforehand if you would like to use the ASIX Electronics VID and PID for your products.
* This can avoid your end customers from downloading the standard AX88178 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 AX88178 based application systems doesn't work with the AX88178 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 AX88178 driver by themselves after sales. In this case, you MUST assign your own unique VID and PID to your AX88178 based devices.
(2) For brand name products, you probably don't want your AX88178-based devices to be compatible with other companies' AX88178-based devices. In this case, you should consider assigning your own unique VID and PID for your AX88178 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 support (firstname.lastname@example.org) for further support.
|Q0012: ||How do I register a Vendor ID from USB-IF?|
|A0012: ||If you are a new USB product developer looking to get a Vendor ID for your company, you can register a Vendor ID from USB Implementers Forum, Inc. Please visit the USB-IF web site (http://www.usb.org/developers/vendor/) for details.|
|Q0013: ||How do I register a MAC/Ethernet address from IEEE-SA?|
|A0013: ||You must first have an OUI or an IAB, to which to append 24 or 12 bits respectively, in a way that makes the resulting 48-bit number unique. Your 24 or 12 bits must be unique within your organization, which will require coordination among all the users of your organization's OUI or IAB. Please visit the IEEE-SA web site (http://standards.ieee.org/regauth/registry_OUI.html) for details. |
|Q0014: ||Do I have to assign a unique MAC address to every AX88178 based devices?|
|A0014: ||Yes, every Ethernet device must have a unique MAC address. You should always assign a unique MAC address in the AX88178 EEPROM.|
|Q0015: ||Do I have to assign a unique serial number to every AX88178 based device?|
|A0015: ||No, it depends on the real requirement of your AX88178 target application. If your end customer may need to install more than one AX88178-based device on your target application, you should assign a different serial number in the EEPROM for every AX88178 device.
If your target application always uses one AX88178 device, you can consider assigning the same serial number in the EEPROM for every AX88178 device for easy maintenance in mass production, especially if you plan to use a Windows PC to test AX88178 based devices repeatedly during the mass production test.
|Q0016: ||Did the AX88178 pass the USB-IF compliant certification?|
|A0016: ||Yes, AX88178 demo board was certified by USB-IF. |
|Q0017: ||Are AX88178 Windows drivers qualified by the WHQL compliant certification?|
|A0017: ||Yes, all AX88178 Vista 32-bit/64-bit and WinXP 32-bit/64-bit drivers were qualified by the MS WHQL certification.|
|Q0018: ||Does the AX88178 Windows driver support the WOL function in S4 (Hibernate)/S5 (Shutdown) mode?|
|A0018: ||The answer depends on whether the USB host controller supports the S4/S5 wake-up function or not since the WOL function of AX88178 USB to LAN devices should be supported on both AX88178 and the USB host controller. Many USB host controllers don't support the WOL function in S4 (Hibernate)/S5 (Shutdown) mode. |
