vmWare Fusion 10 USB3 devices enable

USB Problem after vmWare Fusion upgrade

After the upgrade from Fusion 8.x I was not able to use my USB-Cardreader. Before the upgrade, it always worked. dmesgtold me:
unable to enumerate USB device
Googling the error message did not lead to any result in my case. Therefore I am posting this brief article.
Through some research I found the solution to this.

Solution

There has to be added the line usb_xhci.present = "TRUE" to the .vmx configuration File for the specific virtual machine. Upgrading to Fusion 10 disabled USB3 support for all my VMs.
The .vmx file can be found on Mac PCs within the package of the virtual machine.
