I have a problem using / building the CPIA driver. First, I'd like to say that I don't know a single word of C, so, I'm sorry if the errors seem obvious to you, but I really don't understand :-) My system is a Debian Sid (unstable) and the kernel is a 2.4.3. I first tried to use the driver included in the kernel source tree. It compiles, but it seems not to work : ***** V4L-Driver for Vision CPiA based cameras v0.7.4 Parallel port driver for Vision CPiA based cameras v0.7.4 parport0: ECP direction: reverse parport0: ECP direction: reverse parport0: ECP direction: reverse parport0: ECP direction: reverse parport0: ECP direction: reverse parport0: ECP direction: reverse cpia.c:do_command_extended(1698):40a4 - failed parport0: ECP direction: reverse parport0: ECP direction: reverse CPiA Version: 1.02 (1.0) CPiA PnP-ID: 0553:0001:0100 VP-Version: 1.0 0100 ***** It doesn't detect the cam. I used to use the very same cam on another box and it was OK. I tried to change the parport settings in the BIOS (ECP, EPP, SPP), nothing helps. Questions are : 1) What does that "parport0: ECP direction: reverse" mean ? 2) What does that "cpia.c:do_command_extended(1698):40a4 - failed" mean ? Could this be a hardware problem with my parallel port ? I thought of it because it's an old box (Pentium 166 MMX). How could I test my parallel port ? I tried the latest version as well (1.2), but this one doesn't even compile :-( Here's the error : ****** cpia.c:3906: warning: initialization from incompatible pointer type cpia.c:3907: warning: missing braces around initializer cpia.c:3907: warning: (near initialization for `cpia_template.name') cpia.c:3909: warning: initialization makes integer from pointer without a cast cpia.c:3909: initializer element is not computable at load time cpia.c:3909: (near initialization for `cpia_template.name[2]') cpia.c:3910: warning: initialization makes integer from pointer without a cast cpia.c:3910: initializer element is not computable at load time cpia.c:3910: (near initialization for `cpia_template.name[3]') cpia.c:3911: warning: initialization makes integer from pointer without a cast cpia.c:3911: initializer element is not computable at load time cpia.c:3911: (near initialization for `cpia_template.name[4]') cpia.c:3912: warning: initialization makes integer from pointer without a cast cpia.c:3913: warning: initialization makes integer from pointer without a cast cpia.c:3914: warning: initialization makes integer from pointer without a cast cpia.c:3914: initializer element is not computable at load time cpia.c:3914: (near initialization for `cpia_template.name[7]') cpia.c:3915: warning: initialization makes integer from pointer without a cast cpia.c:3915: initializer element is not computable at load time cpia.c:3915: (near initialization for `cpia_template.name[8]') cpia.c:3916: warning: initialization makes integer from pointer without a cast cpia.c:3916: initializer element is not computable at load time cpia.c:3916: (near initialization for `cpia_template.name[9]') cpia.c:3917: warning: initialization makes integer from pointer without a cast make: *** [cpia.o] Erreur 1 ***** Did I miss something ? The kernel source tree is in /usr/src/linux (a symlink to /usr/src/kernel-source-2.4.3), and the include symlinks are OK as well (/usr/src/linux/include/linux to /usr/include/linux and /usr/src/linux/include/asm to /usr/include/asm). What's wrong ?

Does driver work reliable with 2 usb cameras yet? I have setup 2 Creative webcam IIs in the past and got them to grab alternating frame captures every 30 seconds but the driver inevitably pukes and dies after less than an hour. Does this driver support dual USB cameras yet or will it ever?

Does this driver support dual USB cameras yet or will it ever? It works for me atleast, but I wouldn't rule out a bug. What do you mean by "pukes and dies"?
