if you absolutely want it to be driven from CDC-ACM, try this
new attached patch.
In your original patch you used NO_UNION_NORMAL. That will allow
a device to work without a union descriptor but with the normal
two interfaces. This devices has what in terms of ACM is a collapsed
interface without a union descriptor.
The driver provides for that but then it checks for the exact
number of required endpoints, which is three. Your device has
four endpoints.
The patch ignores a fourth endpoint.
Apply the patch ,
still no /dev/ttyACM0 comes up.
Hi,
please send me dmesg. This should not happen.
