I have a wired mouse connected to my Macbook Pro, OS X 10.9.5. The mouse is powered, but completely unresponsive. The mouse works on my windows machine, and the usb port on my Macbook works with other mouses/devices. The mouse is detected in my System Information as

  USB OPTICAL MOUSE:
  Product ID:   0x0a4c
  Vendor ID:    0x15d9
  Version:   1.00
  Speed:    Up to 1.5 Mb/sec
  Location ID:  0x14100000 / 8
  Current Available (mA):   500
  Current Required (mA):    100

I have tried resetting my PRAM, with no effect.

Does anyone know what steps I can take to fix this?

    Looks like you're not the only one to have problems with this particular brand of mouse. – IconDaemon Mar 17 '15 at 0:55
  • I have a very similar mouse i guess. My problem is it gets disconnected randomly. ``` USB OPTICAL MOUSE : Product ID: 0x0f97 Vendor ID: 0x18f8 Version: 1.00 Speed: Up to 1.5 Mb/sec Location ID: 0x14100000 / 26 Current Available (mA): 1000 Current Required (mA): 100 Extra Operating Current (mA): 0``` So it looks like we got to buy a new mouse :( – D34dman Aug 27 '16 at 17:23

I think your Mac book not providing proper current and voltages. A normal wired mouse requires 5 volts of voltages and 0.9 ampere of current to work properly

  • 1 ampere for a mouse? Must be a heavy duty mouse then :-) USB 2.0 allows up to 500 mA, USB 3.0 up to 900 mA. – nohillside Mar 17 '15 at 8:34
  • sorry it was my mistake... :-) – Zulqarnain Jalil Mar 17 '15 at 9:24
