VMware ACE Administrator’s Manual
Using USB Devices in a Virtual Machine
VMware ACE provides a two-port USB 1.1 controller. You can use up to two USB
devices in your virtual machine if both your host operating system and your guest
operating system support USB. If your host computer supports USB 2.0 devices, you
can use those devices in the virtual machine.
Although your host operating system must support USB, you do not need to install
device-specific drivers for your USB devices in the host operating system if you want
to use those devices only in the virtual machine.
On a Windows 2000 host computer with USB 2.0 support, be sure you are using the
Microsoft USB 2.0 driver for the USB controller. Third-party USB 2.0 drivers, such as
those provided by some motherboard manufacturers, are not supported. For notes on
replacing the third-party drivers, see Replacing USB 2.0 Drivers on a Windows 2000
Host on page 215.
Notes on USB Support in VMware ACE
We have tested a variety of USB devices with this release. In general, if the guest
operating system has appropriate drivers, you should be able to use PDAs, printers,
storage (disk) devices, scanners, MP3 players, digital cameras and memory card
readers.
Modems and certain streaming data devices, such as speakers and Web cams, do not
work properly.
Enabling and Disabling the USB Controller
The virtual machine’s USB ports are enabled by default. If you will not use USB devices
in a virtual machine, you can disable its USB controller using the virtual machine
settings editor.
Connecting USB Devices
When a virtual machine is running, its window is the active window and a USB device
is plugged into the host computer, the device automatically connects to the guest
instead of the host. This autoconnect feature can be disabled in the USB Controller
panel of the virtual machine settings editor (VM > Settings). If all of the virtual
machine’s USB ports are already occupied when it is trying to connect automatically
to a new device, a dialog box gives you a choice: you can either disconnect one of the
existing USB devices to free its port or ignore the new device, allowing the device to
connect to the host.
