解析如下
Each line is tagged with a one-character ID for that line:
T = Topology (etc.)
B = Bandwidth (applies only to USB host controllers, which are
virtualized as root hubs)
D = Device descriptor info.
P = Product ID info. (from Device descriptor, but they won't fit
together on one line)
S = String descriptors.
C = Configuration descriptor info. (* = active configuration)
I = Interface descriptor info.
E = Endpoint descriptor info.
Legend:
d = decimal number (may have leading spaces or 0's)
x = hexadecimal number (may have leading spaces or 0's)
s = string
Topology info:
T: Bus=dd Lev=dd Prnt=dd Port=dd Cnt=dd Dev#=ddd Spd=dddd MxCh=dd
| | | | | | | | |__MaxChildren
| | | | | | | |__Device Speed in Mbps
| | | | | | |__DeviceNumber
| | | | | |__Count of devices at this level
| | | | |__Connector/Port on Parent for this device
| | | |__Parent DeviceNumber
| | |__Level in topology for this bus
| |__Bus number
|__Topology info tag
Speed may be:
1.5 Mbit/s for low speed USB
12 Mbit/s for full speed USB
480 Mbit/s for high speed USB (added for USB 2.0);
also used for Wireless USB, which has no fixed speed
5000 Mbit/s for SuperSpeed USB (added for USB 3.0)
For reasons lost in the mists of time, the Port number is always
too low by 1. For example, a device plugged into port 4 will
show up with "Port=03".
Bandwidth info:
B: Alloc=ddd/ddd us (xx%), #Int=ddd, #Iso=ddd
| | | |__Number of isochronous requests
| | |__Number of interrupt requests
| |__Total Bandwidth allocated to this bus
|__Bandwidth info tag
Bandwidth allocation is an approximation of how much of one frame
(millisecond) is in use. It reflects only periodic transfers, which
are the only transfers that reserve bandwidth. Control and bulk
transfers use all other bandwidth, including reserved bandwidth that
is not used for transfers (such as for short packets).
The percentage is how much of the "reserved" bandwidth is scheduled by
those transfers. For a low or full speed bus (loosely, "USB 1.1"),
90% of the bus bandwidth is reserved. For a high speed bus (loosely,
"USB 2.0") 80% is reserved.

P: Vendor=xxxx ProdID=xxxx Rev=xx.xx

String descriptor info:
S: Manufacturer=ssss
| |__Manufacturer of this device as read from the device.
| For USB host controller drivers (virtual root hubs) this may
| be omitted, or (for newer drivers) will identify the kernel
| version and the driver which provides this hub emulation.
|__String info tag
S: Product=ssss
| |__Product description of this device as read from the device.
| For older USB host controller drivers (virtual root hubs) this
| indicates the driver; for newer ones, it's a product (and vendor)
| description that often comes from the kernel's PCI ID database.
|__String info tag
S: SerialNumber=ssss
| |__Serial Number of this device as read from the device.
| For USB host controller drivers (virtual root hubs) this is
| some unique ID, normally a bus ID (address or slot name) that
| can't be shared with any other device.
|__String info tag
Configuration descriptor info:
C:* #Ifs=dd Cfg#=dd Atr=xx MPwr=dddmA
| | | | | |__MaxPower in mA
| | | | |__Attributes
| | | |__ConfiguratioNumber
| | |__NumberOfInterfaces
| |__ "*" indicates the active configuration (others are " ")
|__Config info tag
USB devices may have multiple configurations, each of which act
rather differently. For example, a bus-powered configuration
might be much less capable than one that is self-powered. Only
one device configuration can be active at a time; most devices
have only one configuration.
Each configuration consists of one or more interfaces. Each
interface serves a distinct "function", which is typically bound
to a different USB device driver. One common example is a USB
speaker with an audio interface for playback, and a HID interface
for use with software volume control.
Interface descriptor info (can be multiple per Config):
I:* If#=dd Alt=dd #EPs=dd Cls=xx(sssss) Sub=xx Prot=xx Driver=ssss
| | | | | | | | |__Driver name
| | | | | | | | or "(none)"
| | | | | | | |__InterfaceProtocol
| | | | | | |__InterfaceSubClass
| | | | | |__InterfaceClass
| | | | |__NumberOfEndpoints
| | | |__AlternateSettingNumber
| | |__InterfaceNumber
| |__ "*" indicates the active altsetting (others are " ")
|__Interface info tag
A given interface may have one or more "alternate" settings.
For example, default settings may not use more than a small
amount of periodic bandwidth. To use significant fractions
of bus bandwidth, drivers must select a non-default altsetting.
Only one setting for an interface may be active at a time, and
only one driver may bind to an interface at a time. Most devices
have only one alternate setting per interface.
Endpoint descriptor info (can be multiple per Interface):
E: Ad=xx(s) Atr=xx(ssss) MxPS=dddd Ivl=dddss
| | | | |__Interval (max) between transfers
| | | |__EndpointMaxPacketSize
| | |__Attributes(EndpointType)
| |__EndpointAddress(I=In,O=Out)
|__Endpoint info tag
The interval is nonzero for all periodic (interrupt or isochronous)
endpoints. For high speed endpoints the transfer interval may be
measured in microseconds rather than milliseconds.
For high speed periodic endpoints, the "MaxPacketSize" reflects
the per-microframe data transfer size. For "high bandwidth"
endpoints, that can reflect two or three packets (for up to
3KBytes every 125 usec) per endpoint.
With the Linux-USB stack, periodic bandwidth reservations use the
transfer intervals and sizes provided by URBs, which can be less
than those found in endpoint descriptor.
