| 7 | <p>You can capture USB traffic for single USB devices or on the root hub level, which captures the traffic of all
|
|---|
| 8 | USB devices attached to the root hub. <ph conkeyref="vbox-conkeyref-phrases/product-name"/> stores the traffic in
|
|---|
| 9 | a format which is compatible with Wireshark. To capture the traffic of a specific USB device it must be attached
|
|---|
| 10 | to the VM with <userinput>VBoxManage</userinput> using the following command: </p>
|
|---|
| 11 | <pre xml:space="preserve">VBoxManage controlvm <varname>VM-name</varname> usbattach <varname>device uuid</varname>|<varname>address</varname> --capturefile <varname>filename</varname>
|
|---|
| 12 | </pre>
|
|---|
| 13 | <p>In order to enable capturing on the root hub use the following command while the VM is not running: </p>
|
|---|
| 14 | <pre xml:space="preserve">VBoxManage setextradata <varname>VM-name</varname> \
|
|---|
| 15 | VBoxInternal/Devices/usb-ehci/0/LUN#0/Config/CaptureFilename <varname>filename</varname>
|
|---|
| 16 | </pre>
|
|---|
| 17 | <p>The command above enables capturing on the root hub attached to the EHCI controller. To enable it for the OHCI or
|
|---|
| 18 | XHCI controller replace <codeph>usb-ehci</codeph> with <codeph>usb-ohci</codeph> or <codeph>usb-xhci</codeph>,
|
|---|
| 19 | respectively. </p>
