[Improvement] Maybe change default gadget vendor & product ID is a good idea?

[SuperMarioSF]

Currently gc is using VID=0x18D1 PID=0xD001, which is corresponding to Android Fastboot device (often called "recovery" interface, some device info site mark this as "Nexus 4 (fastboot)").

Maybe this is the reason Windows just can't pickup RNDIS immediately and required for manual driver selection.

A better USB device ID is VID=0x18D1 PID=0x4EE4, which on some site this matched as "Nexus/Pixel Device (tether+ debug)", which better suited for HandsomeMod use (RNDIS+ADB).

By the way I done some binary hacking, modified my current binary to have 0x4ee4 product ID. Device ID actually changed, and Windows picked up RNDIS device as expected, however the driver doesn't automatically install, leaving in a unconfigured state.

Maybe there are extra works need to be done.

The RNDIS in HandsomeMod looks different from that in Android. Android's RNDIS can be recognized by RouterOS, but HandsomeMod's is not.

Btw which version of RouterOS are you using?
On my RouterOS v6.49.2 on hAP ac2 it works just fine, both default 18D1:D001 and "hacked" 18D1:4EE4 just works, and I'm using this right now.

RouterOS 7.2.3 on RB5009
I did a test, on RouterOS 7.2.3, Android's RNDIS works fine and recognizes as LTE, HandsomeMod's shows up in USB, but doesn't recognize as LTE.
RB5009 doesn't support RouterOS 6, so I used CHR version to test, on RouterOS 6.48.6 CHR, neither Android's nor HandsomeMod's can be displayed in USB.

1. change gc_config.h.in, build.

#ifndef ID_VENDOR
#define ID_VENDOR "0x12d1"
#endif

#ifndef ID_PRODUCT
#define ID_PRODUCT "0x14dc"
#endif

2. add "gc -a ecm" after rndis in /usr/sbin/mobian-usb-gadget

This works well in RotuerOS 7.6 @ RBD52G-5HacD2HnD-TC.

ID from https://wiki.mikrotik.com/wiki/Manual:Peripherals

btw, RouterOS has a strange behavior, if you plug a normal android phone, enable usb tethering, wait lte interface shows up, then unplug it, plug the usb stick, it will work before reboot, with default rndis @ 18D1:D001.

同样的问题，但是我认为更改vid和pid并不能使它在win11上正常工作，我直接patch了二进制中的vid和pid，并把它更改为和我小米手机相同（手机开启usb共享网络是能自动识别并正确安装驱动的），这次识别出的设备中功能里倒是多了RNDIS，但是却并不能安装驱动，我不是太懂这些，也许还需要其他一些字段满足才行。

另外，我在很多其他地方看到了这些

# Note: RNDIS must be the first function in the configuration, or Windows'
# RNDIS support will not operate correctly.
enable_rndis=1
if [ ${enable_rndis} -eq 1 ]; then
cfg_str="${cfg_str}+RNDIS"
func=functions/rndis.usb0
mkdir -p "${func}"
ln -sf "${func}" "${cfg}"

# Informs Windows that this device is compatible with the built-in RNDIS
# driver. This allows automatic driver installation without any need for
# a .inf file or manual driver selection.
echo 1 > os_desc/use
echo 0xcd > os_desc/b_vendor_code
echo MSFT100 > os_desc/qw_sign
echo RNDIS > "${func}/os_desc/interface.rndis/compatible_id"
echo 5162001 > "${func}/os_desc/interface.rndis/sub_compatible_id"
ln -sf "${cfg}" os_desc
fi

这可以用来生成一个RNDIS设备，但是作者的代码写的对我来说有点困惑，这个结构体为什么完全没有用到呢，但是从windows的反应似乎又发送过去了。。。

那个vendor code也和网上其他的一些写的不一样 ，不知道是不是因为这些原因导致驱动会找不到。

手动修改inf在高版本系统下还得关闭驱动强制签名 完全划不来 不知道作者有没有在windows平台下测试过，盼望能早日好用

是的，MSOS描述符没有使用，导致RNDIS设备会被标记为“未知设备”，实际上传入参量就好了。我一开始尝试的hacking方式是使用一个脚本在gc完成动作后手动修改那几个参量。不过我已经向作者提交了一个修复的PR，期望可以合并。
