| 8 | <p>On Windows hosts, a kernel mode device driver provides USB proxy support. It implements both a USB
|
|---|
| 9 | monitor, which enables <ph conkeyref="vbox-conkeyref-phrases/product-name"/> to capture devices when they are
|
|---|
| 10 | plugged in, and a USB device driver to claim USB devices for a particular virtual machine. System reboots are not
|
|---|
| 11 | necessary after installing the driver. Also, you do not need to replug devices for <ph
|
|---|
| 12 | conkeyref="vbox-conkeyref-phrases/product-name"/> to claim them. </p>
|
|---|
| 13 | <p>On supported Linux hosts, <ph conkeyref="vbox-conkeyref-phrases/product-name"/> accesses USB
|
|---|
| 14 | devices through special files in the file system. When <ph conkeyref="vbox-conkeyref-phrases/product-name"/> is
|
|---|
| 15 | installed, these are made available to all users in the <codeph>vboxusers</codeph> system group. In order to be
|
|---|
| 16 | able to access USB from guest systems, make sure that you are a member of this group. </p>
