Hi Sir
My modem is in the list you provide, but with a warning about the
reliability of the driver.
The driver is to be downloaded from the chip supplier, I did it, then
tried to make, then make install.
I got first an error with a static int function declared inside
another function, but written below the first static int declaration.
I commented out the 'static' word, then a make made no error, only
warnings: "pointers differ in signteness", and the make install shows a
not existing reference.
Indeed, the non existing reference make the modules unreliable.
The lsmodemd program doesn't work at all, due to this non existing
reference.
I wonder if I could rewrite the written static int function, above its
actual first declaration. It might suppress the error, without having to
suppress the 'static' modifier.
Here is the /proc/bus/usb/devices content :

As you can see, the Trust K56 V92 USB Modem has no driver, which makes
it unusable.
I keep wondering how to get/compile a driver for this modem.
Thank you very much for your help.
Best regards.
