ed/x/ubuntu list usb devices

ed/x/ubuntu 16 uses a 3 year old file (usb.ids) to list usb devices

$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

you can update this manually if you like

# locate usb.ids

the first three are symlinks to the last one in /var/lib so that is the only one you need to update

# wget http://www.linux-usb.org/usb.ids
# diff usb.ids /var/lib/usbutils/usb.ids | head -20

(optionally) add your favorite missing device(s)


# cp usb.ids /var/lib/usbutils/usb.ids

try lsusb again and your missing devices might now be listed
