Hi, I'm no linux pro, so go easy on me if I'm asking stupid questions

I have an alcatel lte dongle, I have been using it for months

when I first started using it I had to run the following commands every time in order to get it to modewitch

Code: Select all

sudo modprobe usbserial vendor=0x1bbb product=0x0195
sudo usb_modeswitch -W -v 1bbb -p f000 -V 1bbb -P 0195 --message-content 55534243123456788000000080000606f50402527000000000000000000000

and then at somepoint months ago, something happened (I'm not sure what) that made the dongle autoswitch on boot, aslong as usb-modeswitch and ModemManager were installed

I tried to use it the other day only to find it had got itself stuck in firmware update mode, address is now 1bbb:007a
and i can't find any firmware online anywhere for it

if anyone can help me out with this i'd appreciate it


anyway I now have a huawei dongle, and it doesn't behave the same way as the Alcatel dongle

it has three modes afaik

Code: Select all

12d1:1f1e 
12d1:157f
12d1:1592

I can't get it to auto switch from 12d1:1f1e to 12d1:157f on boot

so each time I have to boot then

Code: Select all

sudo usb_modeswitch -v 12d1 -p 1f1e -M 55534243123456780000000000000011062000000101000100000000000000
then
sudo ModemManager
then
sudo NetworkManager

and sometime I have plug and unplug it, then repeat the above three commands

is there a way to get it to auto switch on boot?

also when I manually mode switch it from 12d1:1f1e to 12d1:157f
I see this

Code: Select all

# sudo usb_modeswitch -v 12d1 -p 1f1e -M 55534243123456780000000000000011062000000101000100000000000000

and it works

if I try and switch it to the third mode I see this

Code: Select all
