As long as acm.c line 52 still says "#define DEBUG"
before #include <linux/usb.h>, DEBUG is enabled.
Then to see the messages, you have to enable that message
level in the kernel, but if you used the 'debug' kernel
parameter, you've done that also.

I'm not certain about it, but I don't see how the "not 8-bit
clean" problem can be a USB problem.
