Virtual Machine Controller Configuration in the VMware Host Client
In the VMware Host Client, you can add various controllers to virtual machines, such as USB controllers,
SCSI controllers, Paravirtual SCSI controllers, and SATA controllers. You can also change the SCSI Bus
sharing conguration and the SCSI controller type.
Add a USB Controller to a Virtual Machine in the VMware Host Client
USB controllers can be added to virtual machines to support USB passthrough from an ESXi host or from a
client computer to a virtual machine.
You can add one virtual xHCI controller, one virtual EHCI controller, and one virtual UHCI controller per
virtual machine. With Hardware Version 11, the supported number of root hub ports per xHCI controller is
eight (four logical USB 3.0 ports and four logical USB 2.0 ports).
The conditions for adding a controller vary, depending on the device version, the type of passthrough (host
or client computer), and the guest operating system.
Table 3‑3. USB Controller Support
Controller type
Supported USB Device
Version
Supported for Passthrough
from ESXi Host to VM
Supported for Passthrough from
Client Computer to VM
EHCI+UHCI 2.0 and 1.1 Yes Yes
xHCI 3.0, 2.0, and 1.1 Yes (USB 3.0, 2.0, and 1.1
devices only)
Yes (Linux, Windows 8 and later, and
Windows Server 2012 and later
guests)
For Mac OS X systems, the EHCI+UHCI controller is enabled by default and is required for USB mouse and
keyboard access.
For virtual machines with Linux guests, you can add one or both controllers, but 3.0 superspeed devices are
not supported for passthrough from an ESXi host to a virtual machine. You cannot add two controllers of
the same type.
For USB passthrough from an ESXi host to a virtual machine, the USB arbitrator can monitor a maximum of
15 USB controllers. If your system includes controllers that exceed the 15 controller limit and you connect
USB devices to them, the devices are not available to the virtual machine.

devices present.
n
To use the xHCI controller on a Linux guest, ensure that the Linux kernel version is 2.6.35 or later.
n
Verify that the virtual machine is powered on.
