Insert the device, then run the lsusb command
to see whether it is listed. If lsusb doesn't show it, try the dmesg command
(dmesg returns much more information, so you may have to do a bit of scrolling through the output).
Then report your findings back here.
Be sure to enclose them in "Code" tags (Code tags become available when you click "Go Advanced" at the bottom of the compose post window). That will make them more readable.
