G'day

As much as I love many things about Linux, this steep transition to getting new hardware to work on it is really pain in the back side!!!

Anyway, I got myself a third Webcam that was guranteed to work on linux (the first two didn't work at all!) however, I still can't get it to work.

Kanotix does see the usb webcam:
Code:

root@nito# lsusb
Bus 002 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 001 Device 007: ID 0ac8:303b Z-Star Microelectronics Corp. ZC0303 WebCam
Bus 001 Device 004: ID 046d:c512 Logitech, Inc.
Bus 001 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000


but I can't get it to work on Camorama, or any other webcam software...

I tried looking into "dmesg" to see if any usb actions happening and found this:
Zitat:

Well I tried some USB web cams and frankly I was not impressed. USB cameras have horrible framerates. Videoconferencing happens to be what I do for a living so........ I'm kind of picky. Smilie

Dunno if this is an option for you or not but my own solution to this problem was to buy a cheap wingotv tuner card < $20 and plug an analog video camera into the VIDEO IN port on the tv tuner card. Voila! 40-50 FPS. (Sure USB cams claim they can do 30FPS but I was lucky to see 10).

I like this way becasue:

1) There are no stupid drivers to mess with (tv tuner uses bttv chipset which is supported by Linux kernel),
2) No terrible video due to low frame rates.
3) It just works.

CONS:
Well the video cam is not exactly small and certainly does not fit on my desk, in fact it's kind of big but I use a tripod.

There are alot of tv tuners that work with Linux but I can only recommend this one as it's the only one I've used. AAMOF this is the exact tuner card and site I bought it from. Great company to buy from as well. I've done a fair amount of business with them and never a problem.

mzilikazi, that's a great site, to check, I looked in the modem section, and sure enough, there were linux hardware modems available for a fraction of the price you'd expect:

http://www.surpluscomputers.com/store/m ... m=NET10250

$15 and your modem problems will vanish... sorry, couldn't resist, off topic but that's a good resource posted
