virgin kernel in /usr/src/linux-x.y.zz, you must first copy
19
19
kernel configuration file to /usr/src/linux-x.y.zz/.config,
20
20
then go to the directory and run "make oldconfig" and "make dep".
21
You may also need to type
22
cd /usr/src/linux-x.y.zz
23
make include/linux/version.h
21
24
This should create the missing linux/version.h file.

Then send the same commands to the camera from Linux.

Q: I added IEEE1394 card and now Quickcam doesn't work?

Q: I added IEEE1394 card and now QuickCam doesn't work?
114
117
A: The card driver overwrites /dev/video0..2, use
115
118
insmod ./quickcam.o video_nr=3
116
and then /dev/video3 with Quickcam.
119
and then /dev/video3 with QuickCam.

120
Create /dev/video3 with mknod if necessary.

Q: I get oops after call path video_open/qc_v4l_open/qc_v4l_init/
125
qc_capt_init/qc_frame_init/qc_sensor_init/hdcs_init
126
because qc->sensor pointer was poisoned with 0x5B?
127
A: Some of the driver objects were compiled with debugging
128
and some without. If you change any options (LINUX_DIR or
129
USER_OPT) you must always do first "make clean"!

Q: Can I use more than one camera simultaneously?
133
A: Yes, if you have enough bandwidth in USB bus. A single
134
USB 1.0 bus can drive generally only one camera (there is
135
a report that with using "qcset subsample=y" even two
136
cameras might work in one bus, in theory it shouldn't).
137
If you have just two USB ports in your computer, it
138
typically means that you have just one USB bus.
139
You can attach the camera into the ports and do
140
"cat /proc/video/quickcam/*" to see whether the USB bus
141
number is different or the same in the two ports.
142
A single USB 2.0 bus may or may not work with multiple
143
cameras. It appears to depend on the vendor.

Q: Do I need to patch my kernel with linux-xxx-quickcam.patch?
147
A: No. To be more precise, only if you want to compile the
148
driver statically into the kernel which would be useful
149
usually only if you want to boot Linux from the camera ;)
150
or if you otherwise want to include the camera driver
151
into the kernel source. If you really want to do this,
152
use "make patch", but it will work only with some kernel
added
removed
