Now qcamcontrol gives me (bad) pictures. Bad as they look like a scratched photograph. Strange. I tried xfqcam (with debug=1) and then you see: su-2.01# ./xfqcam -p 0x378 cmd = 0xb, value = 0x9d cmd = 0xb, value = 0x1 cmd = 0xb, value = 0x1 cmd = 0xb, value = 0x9d cmd = 0xb, value = 0x9d cmd = 0xb, value = 0x9d cmd = 0x19, value = 0x20 cmd = 0x1f, value = 0x74 cmd = 0x13, value = 0x50 cmd = 0x11, value = 0xf0 cmd = 0xd, value = 0x1 cmd = 0xf, value = 0x7 cmd = 0x7, value = 0x3 waiting for camera to say "Go!" Without the -p <port> it fails to find the camera. Is there any preference for EPP, ECP etc in the parallel port BIOS setting? I'll do some further experiments.
