我有一个用于 Mightex 相机的自定义模块，该模块已针对我正在使用的 ubuntu 12.04 进行了测试。
我已经安装了它，但是有些东西不起作用。我认为这与此dmesg输出有关：
[ 5.766665] usb 1-1: Manufacturer: Mightex
[ 13.790378] Mightex: module verification failed: signature and/or required key missing - tainting kernel
其他可能有用的信息是：
- 更新3以下可能是最有用的
- 没有
/dev/video1（video0 是我的网络摄像头） lsmod | grep -i mightex给出 2 个条目：Mightex 64952 0videodev 139761 3 uvcvideo,Mightex,videobuf2_core
lsusb输出：Bus 001 Device 002: ID 04b4:0228 Cypress Semiconductor Corp.
在谷歌搜索了一下后，我发现这个链接似乎是问题所在，但我不知道如何解决这个问题。任何帮助都将不胜感激
如果您希望我发布其他信息，请告诉我。

以下是一些相关信息dmesg | grep -i video：

另外，我尝试禁用安全启动按照这里但这并没有改变什么。
更新2
此处这一行：[ 15.114362] video_register_device failed是由这段代码引起的：
if (video_register_device(usbMightex->vdev, VFL_TYPE_GRABBER, video_nr) <0)
{
pr_err("video_register_device failed");
}
更新3
我认为这是实际的模块崩溃和用于调试目的的输出？
