En el trabajo tenemos un monitor multitáctil que aparentemente es un dispositivo de interfaz humana USB (HID) . Se identifica como proveedor 0x4623 producto 0x011a, aparentemente producido por Beijing Honghe Technology Group pero con la marca Newline . Funciona de fábrica en Linux (aparentemente usando un controlador multitáctil HID genérico), pero no en OS X. system_profilerLo describe así:

El dispositivo sirve como una combinación de un teclado (con PgUpy PgDnaccesible mediante control remoto) y un dispositivo de entrada multitáctil. El aspecto del teclado funciona bastante bien: OS X informa que el teclado es de tipo desconocido y solicita presionar una tecla de mayúsculas específica. Como no tengo turno, presiono cualquiera de esos botones de movimiento de página y luego puedo seleccionar manualmente un tipo de teclado. Después de eso, puedo usar las teclas para desplazarme en las aplicaciones.
La entrada táctil, sin embargo, parece no funcionar. El dispositivo se informa como IOHIDPointingy Digitizeren el informe anterior, por lo que parece haber cierta comprensión sobre qué tipo de dispositivo es. Sin embargo, no lo veo controlando el puntero de mi mouse.
Editar: abrí el informe de error de Apple 25216130 sobre esto.
Hay un error en la pila USB de Apple que impide que funcionen algunos dispositivos compuestos USB. Abrí un TSI de Apple y un informe de error sobre esto, y me dieron una solución que me lo solucionó. La solución es simplemente un kext sin código , con esta personalidad agregada al diccionario de IOKitPersonalities:

<key>CFBundleIdentifier</key>

<key>idVendor</key>
<integer>17955</integer>
<key>idProduct</key>

</dict>
(Agregué su VID/PID arriba).
Una futura versión de OS X solucionará (con suerte) esto.
Tenga en cuenta que el kext sin código debe colocarse en /Library/Extensions, y debe estar firmado.
sudo nvram boot-args='kext-dev-mode=1'y reinicié, pero aparentemente el kext todavía no se carga.
