RNDIS 小工具无法启动
我在 TI Davinci dm365 板上构建了带有 Linux 内核的摄像机。
该板支持 RNDIS 驱动程序,因此我的相机可以在 Windows 中“即插即用”。这是某种“USB 以太网”网络适配器。
Windows 加载 RNDIS 驱动程序 usb8023.sys 来与我的硬件交互。
当我插入多个摄像头时,情况就会变得很糟糕,我会遇到很多问题,有时我所有的 USB 端口都会停止工作,但大多数时候,两个摄像头之一会停止工作。
我尝试导入旧驱动程序,复制 usb8023.sys 并为每个摄像头加载单独的驱动程序,但没有成功。我已经检查并仔细检查了我的 IP 设置。
I build video cameras with a Linux kernel on a TI Davinci dm365 board.
This board supports RNDIS drivers so my camera can be "plug and play" in windows. This is some kind of "Ethernet over USB" network adapter.
Windows load the RNDIS driver usb8023.sys to interact with my hardware.
When I have more than one camera plugged-in, Hell breaks loose and I get a lot of problems, sometimes all my USB ports stop working but most of the time, one of the two cameras stop working.
I've tried importing old drivers, copy usb8023.sys and load a separate driver for each cam with no luck. I've checked and double checked my ip settings.

我从德州仪器下载了新版本的驱动程序并重新编译了所有内容。我认为问题在于小工具 PC 启用了 OTG(移动),这允许它在主机和设备模式之间切换。
I downloaded new version of the drivers from Texas Instruments and recompiled everything. I think that the problem was that the gadget pc had OTG (on the go) enabled, which allows it to switch between host and device mode.
每个摄像机的 USB 序列号可能都是相同的。一般来说,Windows 处理这种情况的能力很差。
您需要将每个设备上的USB描述符调整为唯一的ID。
It is likely the USB serial numbers for each of the video cameras is identical. Windows in general handles this situation very poorly.
You need to adjust the USB descriptors on each device to be a unique ID.
