I have a Cocoa App which tries to use a USB-modem (ZyXEL Omni 56k
Plus). This modem does not come with a OS X driver.
The modem uses something called IOUSBCompositeDevice.
When the modem gets a call, my app can read RING, RING, ... (there is
some formating information around the data which I get from
ReadPipeAsync() ).
But I cannot write to the modem. Well, I can write, but I do not get
any reaction, nor any error code. Probably the data to be written needs
some formating information around it - but what?
Can someone point me to some documentation about this
IOUSBCompositeDevice?
Gerriet.
