Sir:
I'm so glad to hear that camera id (093a:2700) was supported by UVC.
But to my surprise, my camera name is not the one list on site
http://linux-uvc.berlios.de/ (iSonicW002). When I plugging my device
and trying camera application, it always return error message like "No
available video device". It seems that my camera isn't recognised by
UVC driver yet. I opened it and found a chip name PAP7501.
I don't know what to do to make my camera work.
Messages below are copy from system. Hope it useful.
Thanks for your great work!
Thanks!
