问题 I asked this previously but Jeff Atwood moved my question to superuser.com. I need a answer programmatically... I want to use built in speakers and usb speakers simultaneously on MAC OS X 10.6. I want to play different files on these (I do not want to play same file on both speakers). Is it possible using cocoa (QTMovie or something else?) or anything else? I have checked the portaudio thing but didn't get how this works! :( I have also tried to send some data to the USB speakers but the

问题 I want to use a BroadcastReceiver to get permission to communicate with a USB device. I am trying to implement it the same way it is done on android website http://developer.android.com/guide/topics/usb/host.html It all works, kind of. But the broadcastReceiver is fireing only after the main activity is created.

问题 We have a usb device and the drivers (.inf, libusb.dll, libusb.sys) and can install it using Windows' Device Installation Wizard (by pointing to the .inf file). However, we need to install the drivers without using the wizard (passively, so the user doesn't need to do anything). Does anyone know how this can be achieved? 回答1: You added the "installer" tag, so I'm assuming you're talking about some kind of installation package, like Windows Installer, InstallShield InstallScript, etc. If that

问题 How can I check the USB socket is plugged or not (Charging with AC / USB)? (android version 2.1 / 2.2) I am writing a wireless charging application that I want to get different types of charging signals ( wireless , AC charging / USB ). I used broadcastReceiver to get the charging signal and found that using wireless charging and AC charging return the same signal (AC charging).

问题 I am designing a security utility for USB sticks that when a memory stick has been plugged in,an email is sent to the user with the computer's name and IP address. I have got the email part working, but do not know how to execute the .exe file I have made when the USB is plugged in.
