I have recently updated my macbook with Lion. Now it keeps on waking up in my bag for some unknown reason. Here is what i get in the console.

An Unknown USB Device (Port 4 of Hub at 0x4000000), may have caused a wake by being connected

I'm not sure what is at the port 4 of Hub? Also what i have discovered is that my bluetooth module apparently is not connected!? What would cause this to happen?

This is from system info:

USB Bus:

  Host Controller Location: Built-in USB
  Host Controller Driver:   AppleUSBOHCI
  PCI Device ID:    0x0aa5 
  PCI Revision ID:  0x00b1 
  PCI Vendor ID:    0x10de 
  Bus Number:   0x04 

Apple Internal Keyboard / Trackpad:

  Product ID:   0x0236
  Vendor ID:    0x05ac  (Apple Inc.)
  Version:  0.77

  Manufacturer: Apple, Inc.
  Location ID:  0x04600000 / 3

IR Receiver:

  Product ID:   0x8242

  Version:  0.16

How do I find what is at port 4? Could it be bluetooth module?

  • If you look in System Information, you might be able to see what that device is. – jtbandes Aug 9 '11 at 21:25

  • Have you tried restarting your computer? – jtbandes Aug 9 '11 at 22:10
  • @jtbandes I have restarted it many times, i even reinstalled OSX from scratch now. So its fully stock. – Luke Aug 9 '11 at 22:22
  • I have ordered a replacement for monitor data cable - as i have also discovered that iSight is not working - since those both work on same cable I'll replace that and see how I go. – Luke Aug 10 '11 at 3:49
