Treiber laden bei boot verhindern

[gima84]

Hi,

ich versuche die letzten Tage ein USB Device so auszuschließen, das der Apple Treiber dafür nicht geladen wird. Aktuell habe ich das kext signing abgeschalteten und eine codeless kext in /System/Library/Extensions hinterlegt.

Inhalt Kext:

Ein
ioreg -p IOUSB -l -w 0
ergibt

+-o HM-CFG-USB@4300000  <class IOUSBDevice, id 0x1000003b5, registered, matched, active, busy 0 (647 ms), retain 10>

Ideen was noch fehlt / was ich falsch mache?
