APC UPS control system manual 214

S:Product=Peracom USB to Serial Converter C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA

I:If#= 0 Alt= 0 #EPs= 3 Cls=00(>ifc ) Sub=00 Prot=00 Driver=serial

E:Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl= 16ms

E:Ad=01(O) Atr=02(Bulk) MxPS= 16 Ivl= 16ms

E: Ad=82(I) Atr=03(Int.) MxPS= 8 Ivl= 8ms

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

I:If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub

T:Bus=00 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 3 Spd=1.5 MxCh= 0

I:If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=mouse

T:Bus=00 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#= 4 Spd=12 MxCh= 0

I:If#= 0 Alt= 0 #EPs= 3 Cls=00(>ifc ) Sub=00 Prot=00 Driver=serial

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:

_ CN.1:
