usbip不能與OpenWRT配合使用

Question

我正在使用帶有openWRT OS版本15.05的MT7688模塊。我沒有安裝USBIP到設備用：

#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 

故障場景：

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

所以，看起來像是在用戶空間打破。是否有人知道它的解決方案？

Answer 1

我花了很多時間來找出解決方案。最後，懷疑是正確的。正如查詢帖子中提到的，來自發布分支的安裝程序ipk沒有用戶空間二進制文件。

解決方案：要擺脫它，我把完整的源來自官方的OpenWrt

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

和編譯後，我得到了在sbin目錄2個二進制

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

哪些需要，我一直在尋找。它現在完美。
