I'm facing the same problem with you. I used a web camera based on zc301p chip. I downloaded the spca5xx driver from http://mxhaard.free.fr/download.html The driver works well on my host PC but have problem on Davinci EVM. I traced the driver and found that a function in drivers/usb/media/spca5xx/spca_core.c init isoc called the usb_submit_urb which returned -16. Then it failed to init. I traced into the kernel and finally found function MGC_LinuxFindEnd failed when it try to find a endpoint. I think there may be some constraints in the usb controller of dm6446
I am trying to use Logitech USB webcam pro5000 with DA-VINCI EVM. Currently
I am running 2.6.19 kernel from *http://source.mvista.com/git/*<http://source.mvista.com/git/> Since the camera is compliant to USB video class, I have used UVC driver available from *http://developer.berlios.de/projects/linux-uvc/*<http://developer.berlios.de/projects/linux-uvc/> The driver gets initialized properly. When I try to run video loopback, I am not getting any video data from the webcam. All the IOCTL calls to the driver succeed but when I start streaming I am only getting empty packets (12bytes long) with just header. Please let me know if somebody has used USB webcam (USB video class) with DA-VINCI EVM. Regards Pawan
