Good day All! How and where in your uvc driver code to be inserted, тo pass in the USB a few bytes?
With libusb this string looks like: #define ON_LED "\x00\x00\x01\xc2\x00\x00\x00" memcpy(buf, ON_LED, 0x7); usb_control_msg(devh, USB_TYPE_CLASS + USB_RECIP_INTERFACE, 1, 0x600, 0x400, buf, 0x7, 1000); The problem is that this code works only when the camera is turned on. --- In kernel code with looks like #define ON_LED "\x00\x00\x01\xc2\x00\x00\x00" buff = kmalloc(0x7, GFP_KERNEL); memcpy(buff, ON_LED, 0x7); ret = usb_control_msg(udev, usb_sndctrlpipe(udev, 0x83), 0x21, 0x1, 0x600, 0x400, buff, 0x7, 1000); uvc_printk(KERN_ERR, "retval = %d\n", ret); But where to insert this code? And it should be sent only after the start the video. _______________________________________________ Linux-uvc-devel mailing list Linux-uvc-devel@lists.berlios.de https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
