Hello,
I am trying to figure out how to get a g_serial device running on the
Acme Acqua board built around the Atmel SAMA5D3. I am using an
unmodified 4.5 kernel with a configuration and a dts file provided by
Acme (originally for kernel version 4.4.5, but the problems I
encountered appear to be t
out a problem on the host side. I
have also tried it with the binary kernel the manufacturer provides,
but I couldn't even replicate this limited success I had. I have not
been able to figure out what I am doing wrong, so any help is
appreciated.
Thanks,
Bálint

No code patches, just the configuration and dts file for the board.

Sometimes I can see another entry in the log:

I did try that, that would explain why it appears only once.

Hello,
I am a total newbie in Linux kernel development (but not in C
programming), and I started to write a USB driver for the DualShock 4
(and also others controllers/equipments for the PlayStation 3/4 while
I'm at it).
My objective is to sanitize what is reported to the userspace (most
games do

I'll have to test the patches to be sure, but it might take a while
for me to get the kernel rolling (I'm currently on the standard, comfy
Debian testing 3.12 kernel)...

Great for me, I don't have to do any work then :-)
As for the pre-built kernel, thanks but I REALLY should do it myself
instead. For now I'm just hacking and learning my way through, but if
I end up someday with something worth contributing back, I won't be
able to just skip this step forever.
