(1) After compiling wireshark and libpcap, I had to enter the following
commands so that wireshark recognizse the one single usb interface i have on
the dell inspiron 3700 laptop.
sudo mkdir -p /dev/bus/usb/.usbfs
sudo mount -t usbfs "" /dev/bus/usb/.usbfs
-obusmode=0700,devmode=0600,listmode=0644
sudo ln -s .usbfs/devices /dev/bus/usb/devices
sudo mount --rbind /dev/bus/usb /proc/bus/usb
sudo mount -t debugfs / /sys/kernel/debug && sudo modprobe usbmon
(2) Once I selected the usb interface for packet capture and display, I
received the following error message:
An error occurred while reading from the file "/tmp/wiresharkXXXXfiyFK7": File
contains a record that's not valid.
(pcap: Linux USB file has a 39-byte packet, too small to have even a Linux USB
pseudo-header)
Note that every time I try to display the content of a captured USB packet, I
receive a similar error message with different number of bytes.
