4g dongle not showing as usb0 after reboot wrt 24.10.1

[redchilis]

is there any way to get this to work

thanks

[redchilis]

this worked, i.e. installing mix of packages from both QMI and RNDIS

thank you @AndrewZ @frollic @mk24
appreciate it!

opkg update && opkg install kmod-usb-net-rndis kmod-usb-serial usb-modeswitch kmod-usb-net-qmi-wwan kmod-usb-serial-option kmod-usb-serial-qualcomm

[redchilis]

the solution in the above post works temporarily

once the lease time of the dhcp in the dongle is up,
the lease does not renew
and
wrt says the "Network device is not present"

it keeps saying "Network device is not present" even after a reboot

only manually disconnecting the dongle and reconnecting the dongle works

my guess is wrt cannot control(renew lease) the dongle using RNDIS(as its a fallback workaround) as the dongle is using QMI (not properly implemented)

is there a possible fix?

thanks

@redchilis

is there a possible fix?

Probably. In another thread I figured out that from major version 24 onwards it seems necessary to install package kmod-usb-dwc3-octeon for my architecture. That brought USB back to life in my installation.

[redchilis]

thanks.

which architecture was that, QMI or RNDIS?

when you say it brought your USB back to life, do you mean it renewed its dhcp? thanks

No, the symptom of my Ubiquity Edge Router 4 was the same as your original symptom.

@redchilis

problem is the device(usb dongle) is not showing up in interfaces

[redchilis]

trying with these packages

opkg update && opkg install kmod-usb-net-rndis kmod-usb-serial usb-modeswitch kmod-usb-dwc3

dongle has been recognized,
will report back if dhcp lease renews or not

Edit:
Does not survive reboot
after reboot, usb0 device not present

3g/4g USB dongle not showing up

OK, there are 4 /dev/cdc-wdmX devices because you have added the device to qmi_wwan without another driver like option being bound to the serial functions. So qmi_wwan has happily tried to use every interface as QMI, except interface 0 which is missing the required interrupt endpoint. The end result is that /dev/cdc-wdm3 is mapped to USB interface 4, which was the one I expected to be QMI. I assume t /dev/cdc-wdm3 responded with a list of QMI subsystems? This is great. I'll go ahead and su…
