我不明白问题是什么以及我该如何安装这个驱动程序？
答案1
与 4.4.0-78 相比，4.4.0-79 似乎存在退化，因此加密狗仅在热插拔时才被识别，重启后将无法工作。使用旧内核时，开箱即用，但 Mint 18.1 上的内核降级解决了这个问题。无论如何，升级到 4.4.0-79 并不紧迫。这不是最优雅的解决方案，但它有效。

从 Linux Kernel 4.19 开始，支持 Asus USB-AC51。
看https://github.com/torvalds/linux/blob/v4.19/drivers/net/wireless/mediatek/mt76/mt76x0/usb.c#L30
您可能想尝试一下。
（尝试安装以下所有 debian 软件包：
linux-image-unsigned-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
linux-modules-4.19.0-041900-generic_4.19.0-041900.201810221809_amd64.deb
来自https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/）

答案是正确的驱动程序版本，从 Myria-de Git 下载。
git clone https://github.com/Myria-de/mt7610u_wifi_sta_v3002_dpo_20130916.git
此版本增加了对此类芯片的许多设备的支持（包括华硕 USB-AC51）。
