How to get invoked handleInterruptPacket override method in case of ACM DEXT(IOUserUSBSerial)?

Question

In ACM Dext handleInterruptPacket override method is not getting invoked by the system. Kindly let me know anything missing.

iig file:

class UserUsbACMControl: public IOUserUSBSerial
{
    virtual void
    handleInterruptPacket(const uint8_t *packet, uint32_t size) override;
}

cpp file:

void UserUsbACMControl::handleInterruptPacket(const uint8_t *packet, uint32_t size)
{

}

But if AsyncIO request sent to Interrupt EP able to get response AsyncIO completion(CompleteAsyncIO). Please check How to access the IOMemoryBufferDescriptor in CompleteAsyncIO, which is sent through AsyncIO on Interrupt EP
