Assuming I have two identical USB keyboards (actually barcode
scanners) connected to a mac, is there any way to tell which of them a
keyboard event came from?
I can get to the keyboard type easily enough, but that only helps when
I have different keyboards:
- (void)sendEvent:(NSEvent *)anEvent {
NSEventType type=[anEvent type];
if(type==NSKeyDown)
{
EventRef ce=(EventRef)[anEvent eventRef];
if(ce)
{
unsigned kbt;
GetEventParameter(
ce,
kEventParamKeyboardType,
typeUInt32, NULL,
sizeof kbt,
NULL,
&kbt
);
NSLog(@"Keyboard type: %d",kbt);
}
}
[super sendEvent:anEvent];
}
Is there some way to, say, get a unique USB device ID or something
like that from an NSEvent or a EventRef?
Thanks
Gerd
