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.
