Hey!
I'am trying to write my own driver for usb serial device. I'am trying to subclass from IOUserUSBSerial
#include <DriverKit/IOService.iig>
#include <USBSerialDriverKit/IOUserUSBSerial.iig>
class NewDriver: public IOUserUSBSerial
{
public:
virtual kern_return_t
Start(IOService * provider) override;
};
but get a lot of errors such as
"IOUserUSBSerial::handleRxPacket(unsigned char*&, unsigned int&)", referenced from:
vtable for NewDriver in NewDriver.iig.o
"IOUserUSBSerial::handleInterruptPacket(unsigned char const*, unsigned int)", referenced from:

NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

ld: symbol(s) not found for architecture x86_64
If I making any implementations of this methods errors staying on. What Im doing wrong? Is there anywhere examples for USBSerialDriverKit? Didn't find anything on github
