Hi Victor, thanks for the patch, there is unfortunately the following
errors in it:
The device list is sorted in ascending order based on vid:pid, you have
inserted all of your added Id's in the wrong place.
19d2:0579 is a ZTE device Id and should be placed among the other 19d2
devices.
You have not included usb-devices output for 19d2:0256 and 2cb7:0100,
and I have strong reasons to believe that they should not be included in
the option driver.
If you are of another opinion then please show the usb-devices output
for them, otherwise remove them from the patch.
You have added support for an interface with the attributes 0a/00/ff ,
there is no such interface in your provided usb-devices listing,
interface Class 0a does not even belong to the option driver.
Thanks
Lars
