usb in use by somebody else

[Robokid]

I am trying to connect a Vex microcontroller to my macbook to program it, but when I plug it in and try to connect I get the error "usb device in use by somebody else."

I have set the filter and downloaded the most recent Extension pack but it still give me that error.

Is there anything I can try?

Wait until the VM has finished starting up before plugging in the device.

You say that you "downloaded the most recent extension pack". I assume that you also installed it.

I have the 4.1.18 extension pack installed, and waited until the VM finished starting up but still receive the same error.

I have read reports from other users where they had to release it from the Mac host before it became available to the guest.

[Robokid]

How do I go about releasing it?

[Perryg]

As a Mac user you should probably know more about it than me, but If I wanted to find out I would Google Safely remove a usb device from a mac

The device is not mounted to my computer so I have no idea where to check next.

That contradicts the first message of this thread: the "someone else" in being "used by someone else" - must be the host.

That is the "bug" and why I have VMware Fusion installed.
