USB lte modem

Nick King
Expert 1280 points

Dear TI,

I have a beagle bone black with debian image 

my projects needs to interface a USB LTE modem to the Beaglebone black

i was looking on the internet for a LTE USB plug and play modem there were quite a lot of them sierra wireless,ZTE, huawei and so on now i did read USB specifications which says the host detects the device by asking for device descriptors which define the device class and what drivers need to be loaded. 

my question:

1) linux kernel does this automatically and that i do not need to load/install any additional kernel/libraries/bin files am i correct ?

2) if answer is NO then can you please let me what additional kernel modules or libraries/bin files to be loaded/installed so that LTE modem works fine on BBB?

Regards

Nick

    Hi Nick,

    Yes, they should be detected by linux kernel.

    If you have any problem, it's most likely because the appropriate vendor driver is not enabled in kernel defconfig file (you can enable it in menuconfig as well). You can check which usb wireless devices are supported in: drivers/net/usb/ folder.
    If the driver source is not present in the kernel directory, then you should download it & the instructions how to integrate it in your kernel from the vendor.

    Best Regards,
    Yordan
