Enable ACM in kernel

[punk45rock]

I was trying to plug my Arduino uno into my Udoo quad but it does not appear to be assigned to a serial port, which i believe should appear as ttyACM*. when searching the kernel github page i see these relults https://github.com/patrykk/linux-udoo/search?utf8=%E2%9C%93&q=ACM. Is it possible to get these devices supported in your next kernel release?

I hope adding this is enough?

Try to re-compile kernel by yourself, I won't be rebuilding soon.

that needs lib #66 as weell https://github.com/igorpecovnik/lib/issues/66

Added that to, thanks Horst.

Hey guys,

 

facing a similar problem.

I'm trying to configure the TI CC2531 dongle with the TI Z-Stack Linux Gateway to manage a Zigbee network.

 

I have different boards running armbian:

- lamobo-r1, armbian jessie with mainline kernel

- cubietruck, armbian jessie with mainline kernel

 

If I plug den CC2531 dongle into the lamobo-r1 it is recognized and

created as /dev/ttyACM0,

 

ls -ld /dev/ttyA* :

 

crw-rw---- 1 root dialout 166, 0  /dev/ttyACM0

 

I can connect to it and configure it.

 

On my preferred board the cubietruck, it wont work as intended:

 

-rw-rw---- 1 root   /dev/ttyACM0

 

The missing c* already indicates that I wont be able to talk to the device via uart, thus also the Z-Stack communication failed.

But if I try running the legacy kernel on the cubietruck it works like a charm.  I also tested an Arduino out of curiosity,this

some how works on the vanilla and the legacy kernel.

 

Might a recompile of the kernel help e.g. identifying a missing module or might this be related to an incompatibility of 

the vanilla kernel with the cubietruck hardware?

 

Best Regards,
