Hello everyone,
I got a USB DSL modem, here is the output of USB Prober for the device:

I want to create an interruptEventSource to add it the workloop but
when I try to create it I can't find the source of the interrupt:
I do the following code:
interruptSource = IOInterruptEventSource::interruptEventSource(this,
(IOInterruptEventAction)&com_trendchip_driver_TC3160::
interruptOccurred,
provider,
0);
//
if (!interruptSource) {
USBLog(3, "startInterrupt : Failed to create interrupt event
source!\n");
// Handle error (typically by returning a failure result).
}
if (fWorkLoop->addEventSource(interruptSource) != kIOReturnSuccess) {
USBLog(3, "startInterrupt : Failed to add interrupt event source to
work loop!\n");
// Handle error (typically by returning a failure result).
}
The device got an interrupt pipe so I should be able to create
interruptSource.
If that's not the right way to do that how should I handle the
interrupt send by the device ?
thanks for your time
best regards
Mathieu
