我买了LOTEKOO USB无线网络适配器，强大的5 5dBi天线600 from双带从亚马逊。我一直试图让它与我的Ubuntu一起工作：“Linux4.15.0-34-泛型#37~16.04.1-Ubuntu Aug 28 10:44:06 UTC 2018 x86_64 GNU/Linux”。首先，我根据每个关于GitHub的说明编译并安装了驱动程序。但是当我插入USB时却没有检测到。看看syslog：

按照一些说明，我创建了一个udev规则文件：

代码语言：javascript
运行
复制
db2admin@pluto:/etc/udev/rules.d$ cat 90-myrules.rules 
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="c811", ATTRS{serial}=="123456"

当我看到以下输出时：

这个答案应该归功于@chili555 555，他在上面的评论中给出了正确的答案。对于其他可能在这方面苦苦挣扎的人来说，这里有几个步骤:首先启用/安装dkms。

代码语言：javascript
运行
复制
sudo apt-get install dkms

下面是我遵循的命令序列：

代码语言：javascript
运行
复制
sudo apt-get install dkms
cd Downloads/
git clone https://github.com/whitebatman2/rtl8821CU.git
cd rtl8821CU/
export DRV_NAME=rtl8821CU
export DRV_VERSION=5.2.5.3
set |grep DRV
sudo mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
git archive master | sudo tar -x -C /usr/src/${DRV_NAME}-${DRV_VERSION}
cd rtl8821CU/
git archive master | sudo tar -x -C /usr/src/${DRV_NAME}-${DRV_VERSION}
sudo dkms add -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms build -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms install -m ${DRV_NAME} -v ${DRV_VERSION}
