Hi! I'm trying to get an Hauppauge Live Usb 2 video grabber to run on on Omap4 (Gumstix Duovero). I'm using Sakomans omap-3.6 head kernel sources from http://git.sakoman.com/git/gitweb.cgi?p=linux.git;a=summary . The hardware is successfully detected on the USB host port, the driver loads perfectly including the firmware. With v4l2-ctl --all I can see if thee video signal on the composite port is ok or if the sync is lost, but as soon as I use any v4l2 software (e.g. yavta) to grab some images the driver uses 100% of the cpu, returns the first image and after some seconds I see EPROTO (-71) errors in dmesg. First I get " cx231xx #0: can't change interface 3 alt. no to 0 (err=-71)" and then "UsbInterface::sendCommand, failed with status --71" I did the following tests: - checked that all patches I found (e.g from http://git.linuxtv.org/mchehab/cx231xx.git) are included in my kernel, including the URB DMA related patches and the timing patches - tried the same on an Gumstix Overo (Overo Fire and Overo WarerStorm) on several different header boards. - tried older kernels (3.2 and 2.6.32) with rougly the same results or known errors due to missing patches Unfortunately I can't use other capture devices because the final hardware is custom made with the cx23102 chip :-( I could use an omap3 instead of an omap4, but omap4 is preferred. My questions are: - Did anybody ever used the cx231xx driver with an omap3 or omap4 successfully? - If yes, could you let me know the kernel version and maybe the config? - Any hints what I could try? I'm an expirienced embedded C programmer but I dont have much expirience in USB kernel drivers. Any help is greatly appriciated! Thanks in Advance!
