Hello, Could someone give me a hand? I'm having trouble getting a USB Camera to work on my BeagleBone Black. I'm using a 5V@1A adapter (I thought it could be a power issue), but it didn't solve it. I can provide the following information of my system:

I tried with streamer, mjpg-streamer and ffmpeg but always get timeout. My impression is that not all the modules are being loaded. For instance when I plug the camera on my laptop I get the following modules on lsmod: $ lsmod ... uvcvideo 80885 0 videobuf2_vmalloc 13216 1 uvcvideo *videobuf2_memops 13362 1 videobuf2_vmallocvideobuf2_core 40664 1 uvcvideovideodev 134688 2 uvcvideo,videobuf2_core* ... The 3 last aren't being loaded on the BBB. Do you have any suggestions? What could it be? Thanks a lot for any hints! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
