Selecting only the "T:" and "I:" lines from this (for example, by using
"procusb ti"), we have:
T: Bus=00 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
T: Bus=00 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 4

Physically this looks like (or could be converted to):
+------------------+
| PC/root_hub (12)| Dev# = 1
+------------------+ (nn) is Mbps.
Level 0 | CN.0 | CN.1 | [CN = connector/port #]
+------------------+
/
/
+-----------------------+
Level 1 | Dev#2: 4-port hub (12)|
+-----------------------+
|CN.0 |CN.1 |CN.2 |CN.3 |
+-----------------------+
\ \____________________
\_____ \
\ \
+--------------------+ +--------------------+
Level 2 | Dev# 3: mouse (1.5)| | Dev# 4: serial (12)|
+--------------------+ +--------------------+
Or, in a more tree-like structure (ports [Connectors] without
connections could be omitted):
PC: Dev# 1, root hub, 2 ports, 12 Mbps
|_ CN.0: Dev# 2, hub, 4 ports, 12 Mbps
|_ CN.0: Dev #3, mouse, 1.5 Mbps
|_ CN.1:
|_ CN.2: Dev #4, serial, 12 Mbps
|_ CN.3:
