5. Test USB functionality—Check for USB enumeration.
· (Windows systems) The Device Manager shows Sierra Wireless items
under the Ports - (COM & LPT) entry. The devices shown depend on the
module type. For example:
·
MC8xxx
· MC57xx
· (Linux systems) Enter the command ls /dev/tty/USB* and then record and
compare the results with those from Step 3. If there are any new ttyUSBn
devices, then the modem has enumerated successfully. (There should be
three or seven new devices, depending on the module type.) For example:
· MC8775/MC8775V/MC8780/MC8781/MC8700 (with no other USB
devices connected):
(The AT port is the third new enumerated device— /dev/ttyUSB2.)
· MC5727/MC5727V/MC5728V/MC8201/MC8700/MC8790/MC8790V/
MC8791V/MC8792V/MC8795V (with one other USB device already
connected and assigned to ttyUSB1):
(The AT port is the fourth new enumerated device— /dev/ttyUSB4.)
