For some reasom when I call WritePipeAsync(), I get error code e0002c2
(kIOReturnBadArgument). I Googled the heck out of it and haven't found any
similar issues. If I use WritePipe(), it works great. Here is my code:
char gBuffer[64] = {0};
gBuffer[0] = 1;
gBuffer[1] = 1;
gBuffer[2] = 's';
IOReturn kr = (*interface)->WritePipeAsync(interface, 2, gBuffer,
sizeof(gBuffer),
(IOAsyncCallback1)WriteCompletion, (void *)interface);
Note: this is taken from Apple's USB sample code.
