| 9 | On Windows hosts, a kernel mode device driver provides USB proxy
|
|---|
| 10 | support. It implements both a USB monitor, which enables
|
|---|
| 11 | <ph conkeyref="vbox-conkeyref-phrases/product-name"/> to capture devices when they are plugged in, and
|
|---|
| 12 | a USB device driver to claim USB devices for a particular
|
|---|
| 13 | virtual machine. System reboots are not necessary after
|
|---|
| 14 | installing the driver. Also, you do not need to replug devices
|
|---|
| 15 | for <ph conkeyref="vbox-conkeyref-phrases/product-name"/> to claim them.

|

| 18 | On supported Linux hosts, <ph conkeyref="vbox-conkeyref-phrases/product-name"/> accesses USB devices
|
|---|
| 19 | through special files in the file system. When <ph conkeyref="vbox-conkeyref-phrases/product-name"/> is
|
|---|
| 20 | installed, these are made available to all users in the
|
|---|
| 21 | <codeph>vboxusers</codeph> system group. In order to be able
|
|---|
| 22 | to access USB from guest systems, make sure that you are a
|
|---|
| 23 | member of this group.
