EM7455 Adapter off EBay

So I bought a adapter off ebay and installed it, this shows in device manager as per the below

Why is there the bottom 3? and how do i resolve it.

I keep seeing things about send AT commands and i know how to use putty, but theres nothing to say what com port its on

Also how can you tell if it is carrier locked e.g. Vodafone / EE?

thanks

Did you download and install the usb driver from source.sierrawireless.com ?

Yes, I installed them, but it still doesnt pick up the bottom 3

I tried firmware update but get the bellow

but im using a dell tablet?

Installed lenovo drivers and get the bellow but them 3 say code 10 failed to start

which driver did you install in source.sierrawireless.com?

just the generic one

ive installed the lenovo one and the modem and netowrk now show as working

but if i try and connect to the modem come port it opens but i cant type any thing in the command box

seen something where it says boot to ubuntu to run some codes, but as its a taplet i have no keyboard to type them in terminal

You can use usb keyboard

Yeah i found the onscreen one,

but its still same, tried drivers from that page both lenovo and dell, both say not intended for this PC even though its a Dell

tried to extract them and manually put them on and get “code 10” device cannot start

How about the driver in source.sierrawireless.com?

Finally done it

So first off from the below, make a bootable Ubuntu USB

Then open terminal and run sudo minicom -s

Change the serial settting to /dev/ttyUSBX2

save changes to default and exit

Now type these, the text wont appear on screen but jsut pres enter after each and it should return OK

AT!ENTERCND=“A710”

AT!USBVID=1199
AT!USBPRODUCT=“EM7455”
AT!PRIID=“9904802”,“001.001”,“Generic-Laptop”
AT!RESET

then reboot to windows and install generic drivers and firmware
