Hi I have an HP Touchsmart TX2-1020us, with a Suyin camera with USB Id 064e:a104. It is supposed to be an 1.3 Mpixel camera, from specs.
It is not working with several programs, luvcview, fswebcam, uvccapture. With luvcview, it freezes the program with a borked image; even with a Ctrl-C it does not end, must be killed from command line, in another terminal. Output of execution is luvcview 0.2.4 SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 Stream settings: Frame format: YUYV (MJPG is not supported by device) Frame size: 320x240 (requested size 640x480 is not supported by device) Frame rate: 5/1 fps (requested frame rate 30 fps is not supported by device) Quit signal received. ^C Kernel is 2.6.31.rc8 (Ubuntu Karmic development version); uvcvideo module from kernel, version 0.1.0. filename: /lib/modules/2.6.31-8-generic/kernel/drivers/media/video/uvc/uvcvideo.ko version: v0.1.0 license: GPL description: USB Video Class driver author: Laurent Pinchart <[email protected]> srcversion: FED3F6A6B7C99CADE0DEEB5 I have searched the list and not did not found any reference to this model. lsusb (version 0.82) output is: $ sudo lsusb -d 064e:a104 -v Bus 005 Device 002: ID 064e:a104 Suyin Corp.
