Hello everyone,

I come from days and days of searching with only frustration, and this thread bring me on this forum

Before updating the dongle, it was necessary to manually send the commands `usb_modeswitch ... -W -R -w 400` and `usb_modeswitch ... -W -R -w 400` ... but with the up-to-date firmware of this dongle, there is no need of theses commands on my Raspberry PI OS (lastest, based on bookworm).

Then I replaced my OS by a standard and fresh Debian Bookworm and with the SAME usb_modeswitch version and configuration and this time, it is not working ...

It looks the dongle switch to the right mode in the two OS, i have the similar dmesg :

Code: Select all

And similar lsusb :

But ends with not the same interface :

Any ideas ?
