Seems so.
Note BeOS doesn't have the usb_scanner driver by default, so it must be 
Zeta has it, as well as the headers.

I also sent the diffs to the BeSANE maintainer, 
Philippe Houdoin <philippe dot houdoin at free dot fr>.

Yes, someone brought one once at a user meeting, that's why I had to do 
that because we don't have libusb.
I was able to scan, so I suppose it works, didn't test it much though, 
and I heard its PSU broke since then.

I see, makes sense.

As I said, it worked for me, but it's better to have others test it, 
though I didn't remove the libusb code there... 
(so if you test, make sure you don't configure with libusb 
or force it off).

You tell me :)

That seems like old code from BeSANE (which was quite hacky).
maybe it goes to AC_CHECK_HEADERS, but I don't know which files it's 
needed for.
Or isn't there a globaly included .h anyway...

Hmm yeah, I have a getpass in an external libmoreposix of mine anyway, 
and it should get into Zeta's libroot at some point anyway.

Hmm right...
but it doesn't give something to use instead.
getpassphrase() isn't much better...

I have this in libmoreposix, quite ugly but works, though it doesn't 
check for a tty on stdin, but we don't have /dev/tty in beos anyway:

/* NOT threadsafe */
static char getpass_buff[258];

char *getpass(const char *prompt)
	struct termios tios;
	char *ptr;

	if (prompt)
		printf("%s", prompt);
	if (ioctl(0, TCGETA, &tios) < B_OK)
		return NULL;
	tios.c_lflag &= (~ECHO);
	if (ioctl(0, TCSETA, &tios) < B_OK)
		return NULL;
	ptr = gets(getpass_buff);
	tios.c_lflag |= ECHO;
	if (ioctl(0, TCSETA, &tios) < B_OK)
		return NULL;
	return ptr;

char *getpassphrase(const char *prompt)
	return getpass(prompt);

Agreed, I didn't like it either, but it's again old BeSANE code which 
should be cleaned up. I leave that to the maintainer :)
