check packet flow on linux with
iptstate
this uses the libnetfilter_conntrack part of linux kernel
It analyses all nics
If you can see traffic on a particular port and you want to see if it is coming from your machine check your /etc/services file to see if a known service is listed for it.
If you need more info use netstat:
netstat -nap
(you can pipe this to grep to analyse specific ports)
netstat -nap | grep ":22\s"
Look at devices
/sbin/lspci
or
/sbin/lspci -vv
for more detail
look for usb only
/sbin/lspci | grep -i usb
you can also run
/sbin/lsusb

/lib/modules/
find the loaded ones using
