Is the device configured by Windows or not? If not, most likely your device descriptor is not correct. > It's my device's problem, have to figure it out. But some hints from you > experts should be helpful:-) You can try to use USBView to check if the device is configured or not. http://www.ftdichip.com/Support/Utilities.htm You can also post your descriptor C file so that people can take a look at your intended descriptor. Since you use Silabs' old example, maybe you want to check if the original example works or not (if you have their development kit). You may also want to check out their latest example. -- Xiaofan ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
