[gentoo-user] media-video/gspcav1 or kernel module?

[Iain Buchanan]

Hi all,

I recently upgraded from 2.6.26 to 2.6.28.  My el-cheapo webcam (lsusb:
0c45:602c Microdia Clas Ohlson TWC-30XOP WebCam) used the
media-video/gspcav1 driver, but that no longer compiles:

/var/tmp/portage/media-video/gspcav1-20071224/work/gspcav1-20071224/gspca_core.c:54:27: error: asm/semaphore.h: No such file or directory
/var/tmp/portage/media-video/gspcav1-20071224/work/gspcav1-20071224/gspca_core.c: In function 'spca5xx_ioctl':
/var/tmp/portage/media-video/gspcav1-20071224/work/gspcav1-20071224/gspca_core.c:2463: error: implicit declaration of function 'video_usercopy'

etc.

I discovered a number of gspca modules in the kernel:

gspca_spca508
gspca_spca506
gspca_spca505
gspca_spca500
gspca_spca501
gspca_spca561

but I can't find out which one suits my webcam.  usb id is above, and
it's a freebie from a pc store, so it's branded with their logo and
comes with no technical notes.

I've tried loading each gspca_spca5xx module one by one, but none of
them creates a video device (that I can tell).

Any hints for what module to use?

thanks!

If you boot 2.6.26 it should be easier to spot the right module. Anyway 
I encountered the same problem with my gspca561, IIRC there's a problem 
with 2.6.28 kernel.

Waiting for a kernel upgrade I lent my webcam to a vista user...

HTH. Ciao

Maybe this page will point you to the right driver:

I just backed out gspcav1 and compiled all the kernel drivers as modules and 
just plugged the webcam in; the kernel works out which ones to use. 

# lsmod | grep spca
gspca                 621584  0
gspca_zc3xx            48320  0
gspca_main             22656  1 gspca_zc3xx
compat_ioctl32          8256  2 gspca,gspca_main
videodev               34112  3 gspca,gspca_main,compat_ioctl32

However, you are not out of the woods yet! You will probably need the libv4l 
libraries installed to get spcaview to work. Skype and kopete still 
completely fail to find the camera. :( There is a long thread on the Gentoo 
fora about this.

I didn't use the kernel module in 2.6.26, I used media-video/gspcav1,
which gave me /lib/modules/2.6.25-tuxonice-r6/usb/video/gspca.ko which
"just worked" with linux, skype, etc.

I can't wait! I'm a child of the here-and-now generation!

I found that before I emailed, but I didn't glean much information from
it.  Looking at it again, I see that the pci id's are repeated later
with links (which confused me a bit) and I see that I should try
CONFIG_USB_SN9C102

I'll try that out when I get back to where I'm staying :)
