Hi Henning, here's a copy of the email I sent to the maintainer of the fb630u backend. It gives the full debug output, the last lines where it blocks being the same as those I already posted on this list.
I got no reply from Nathan so I have nothing more to contriute from him. As you can see communication seems to go quite well at first but then gets stuck in a loop with no apparent timeout. regards, Peter. ------- Forwarded message ------- From: [email protected] To: "Nathan Rutman" <[email protected]> Subject: [canon630u] read_byte(fd, 0x01, &result); /* got 00 */ Date: Sun, 23 May 2004 22:27:03 +0200 Hi, here is the full debug output from scanimage. The final line just repeats until I kill the process or unplug the scanner. This should give you a good idea of what is happening. I'm an active member of forums.gentoo.org and there seem to be quite a lot of posts with very similar pbs. So once I get it working will post the solution. Thanks again for any help or suggestions.
