How do I capture device specific USB packets with tshark?
I know the Device ID(0x0009), and Vendor ID(0x08f7) how can I specify the exact device I want to capture, via tshark?
You might want to have a look at the tshark(1) - Linux man page and the tshark - Wireshark man page and the
-i switch options.
Additionally have a look at the Wireshark Capture Filters and the Wireshark USB Display Filter Reference which you may find useful in building applicable commands to filter and suit your needs.
You may be able to use a capture filter expression such as
usb.device_address == # or
usb.addr == # with the
-f switch to tell the sniff to only capture packets from a particular USB device.
A capture or read filter can either be specified with the -f or -R
option, respectively, in which case the entire filter expression must
be specified as a single argument (which means that if it contains
spaces, it must be quoted), or can be specified with command-line
arguments after the option arguments, in which case all the arguments
after the filter arguments are treated as a filter expression. Capture
filters are supported only when doing a live capture; read filters are
supported when doing a live capture and when reading a capture file,
but require TShark to do more work when filtering, so you might be
more likely to lose packets under heavy load if you're using a read
filter. If the filter is specified with command-line arguments after
the option arguments, it's a capture filter if a capture is being done
(i.e., if no -r option was specified) and a read filter if a capture
file is being read (i.e., if a -r option was specified).
-f <capture filter>
Set the capture filter expression.
This option can occur multiple times. If used before the first
occurrence of the -i option, it sets the default capture filter
expression. If used after an -i option, it sets the capture filter
expression for the interface specified by the last -i option occurring
before this option. If the capture filter expression is not set
specifically, the default capture filter expression is used if
-i <capture interface>|-
Set the name of the network interface or pipe to use for live packet
Network interface names should match one of the names listed in
"tshark -D" (described above); a number, as reported by "tshark -D",
can also be used. If you're using UNIX , "netstat -i" or "ifconfig -a"
might also work to list interface names, although not all versions of
UNIX support the -a option to ifconfig.
If no interface is specified, TShark searches the list of interfaces,
choosing the first non-loopback interface if there are any
non-loopback interfaces, and choosing the first loopback interface if
there are no non-loopback interfaces. If there are no interfaces at
all, TShark reports an error and doesn't start the capture.
Pipe names should be either the name of a FIFO (named pipe) or ''-''
to read data from the standard input. Data read from pipes must be in
standard libpcap format.
Note: the Win32 version of TShark doesn't support capturing from
