usbip不能与OpenWRT配合使用

Question

我正在使用带有openWRT OS版本15.05的MT7688模块。我没有安装USBIP到设备用：

#opkg install http://downloads.lede-project.org/releases/17.01.1/targets/ramips/mt7688/packages/kmod-usbip-client_4.4.61-1_mipsel_24kc.ipk 
#opkg install http://downloads.lede-project.org/releases/17.01.1/targets/ramips/mt7688/packages/kmod-usbip-server_4.4.61-1_mipsel_24kc.ipk 
#opkg install http://downloads.lede-project.org/releases/17.01.1/targets/ramips/mt7688/packages/kmod-usbip_4.4.61-1_mipsel_24kc.ipk 

故障场景：

root@mylinkit:/# usbip 
-ash: usbip: not found 

所以，看起来像是在用户空间打破。是否有人知道它的解决方案？

下面是它显示内核模块安装日志：

root@mylinkit:/# lsmod|grep usbip

Answer 1

我花了很多时间来找出解决方案。最后，怀疑是正确的。正如查询帖子中提到的，来自发布分支的安装程序ipk没有用户空间二进制文件。

解决方案：要摆脱它，我把完整的源来自官方的OpenWrt

- `git clone https://github.com/openwrt/openwrt` 
- `make menuconfig` 
- *Enabling from menuconfig* 
- `networking->usbip` `networking->usbip-client` and `networking->usbip-server` 

和编译后，我得到了在sbin目录2个二进制

/usr/sbin/usbip 
/usr/sbin/usbipd 

哪些需要，我一直在寻找。它现在完美。
