The USB Device View shows the USB Host Controllers, Hubs and Devices present in
your system, hierarchically organized by connection as a tree.
Clicking an item in the device view shows the information relevant to that item
(Connection Information, Configuration/Interface/Endpoint/Device Descriptors) in the Info
view. Each item in the device tree has a check box. To include an item while capturing,
the check box corresponding to that item should be checked before starting capture
operation.
