I’ve just received a new AR750 with firmware version and new Sprint USB730L with the intent of using them together. They both work fine individually, the USB730L plugged into my Fedora 28 laptop is fine and the AR750 can connect as a repeater to the existing wireless but is not recognized by the basic UI. From the OS it is recognized and it looks like the appropriate modules are loaded:
root@GL-AR750:/dev# lsmod |grep usb

usbserial 18427 4 option,usb_wwan,sierra,cp210x
FWIW I see the AR750 periodically retrying the modem, or at least that’s my take on this:
[ 1797.361905] usb 1-1.2: new high-speed USB device number 35 using ehci-platform
[ 1797.521311] cdc_ether 1-1.2:1.0 eth2: register ‘cdc_ether’ at usb-ehci-platform-1.2, CDC Ethernet Device, 00:15:ff:82:25:70
[ 1807.452462] usb 1-1.2: USB disconnect, device number 35
[ 1807.458012] cdc_ether 1-1.2:1.0 eth2: unregister ‘cdc_ether’ usb-ehci-platform-1.2, CDC Ethernet Device
[ 1808.201872] usb 1-1.2: new high-speed USB device number 36 using ehci-platform
[12691.291815] usb 1-1.2: USB disconnect, device number 36
[12692.035017] usb 1-1.2: new high-speed USB device number 37 using ehci-platform
These are not plug/unplug events they occur while the modem is plugged in.
Based on articles I’ve seen I’m suspecting that this is an End User Mode vs. Enterprise Mode thing but all of those articles are a tad old and I figured this would have been addressed by now. Any advise out there that would not undermine official support?
Thanks!
