Debian 64-bit Question

[MorganAbrams]

Has this been updated to work on Debian Bullseye 64-bit?

I tried setting it up the same way I have done for Bullseye 32bit and it works on 32-bit but when I try it on 64-bit it doesn't connect in the first place but still repeatedly gives the message below as if it connected in the first place.

In FunctionFs or Gadget mode ?

FunctionFS.

Please recompile it with the debug output with CFLAGS="-DUSE_SYSLOG -DDEBUG" and post here the logs.

If possible also try to force the compilation in 32bits on the 64bits debian with the gcc -m32 option. You may need to install multilib (sudo apt-get install gcc-multilib). If umtprd works this way this means that i have to fix a structure/variable type.

On Debian Bullseye, compiled with -DUSE_SYSLOG -DDEBUG, we only get this in /var/log/messages:

So, it starts correctly, but we get no useful log messages. It's like it never detects the OTG port being connected.

Raspbian also does not include a gcc-multilib package for some reason, so I'm unable to test compiling a 32 bit binary on a 64 bit system.
