[已解决]关于RTL8188GU芯片的USB无线网卡

我试着编译RTL8188GU无线驱动失败
lsusb结果

Bus 003 Device 007: ID 0bda:b711 Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (After Modeswitch)

在/lib/udev/rules.d/40-usb_modeswitch.rules 以及/usr/share/usb_modeswitch中并没有发现0bda:b711
实体机上ip a结果

尝试编译https://github.com/McMCCRU/rtl8188gu提供的驱动不成功

我把iusses(https://github.com/McMCCRU/rtl8188gu/issues/14里提到的文件复制粘贴到rtl8814au/os_dep/linux/里替换掉了原来的recv_linux.c

Re: [已解决]关于RTL8188GU芯片的USB无线网卡

我试着编译了一下，没什么特别问题， Linux >= 5.12 需要在 os_dep/linux/recv_linux.c 的 353 行做一个小改动，也就是你提到的那个 issue 中的说的那个：

#ifdef CONFIG_RTW_GRO
        if (pregistrypriv->en_gro) {
#if LINUX_VERSION_CODE < KERNEL_VERSION(5, 12, 0)
            if (rtw_napi_gro_receive(&padapter->napi, pskb) != GRO_DROP)
                rx_ok = _TRUE;
#else
            rtw_napi_gro_receive(&padapter->napi, pskb);
            rx_ok = _TRUE;
#endif
            goto next;
        }
#endif /* CONFIG_RTW_GRO */

这个解决了 'GRO_DROP' undeclared 这个问题，然后就好了，内核模块编译出来了。

但是，你的编译日志中的前面那个类型错误的问题我没有找到相关的讨论。

另外，楼主你没有装 bc

/bin/sh: line 1: bc: command not found

Re: [已解决]关于RTL8188GU芯片的USB无线网卡

在仔细地看了一下那个类型错误问题之后，我发现你用的代码中似乎存在一些错误的改动，rtw_os_alloc_msdu_pkt 函数的类型与头文件中声明的类型不匹配，但是我从 github 上下载到的代码中的 rtw_os_alloc_msdu_pkt 参数声明是正确的，可能是你的修改导致了这个问题。

我建议你试一下下面的步骤：

1、安装 bc
2、从 https://github.com/McMCCRU/rtl8188gu 重新下载一份干净的 master 分支代码
3、对 os_dep/linux/recv_linux.c 的 353 行处手动做 Linux 5.12 Patch
4、make

在另一个帖子里，bc 未找到那个错误出现N次了，我跟他说先装一下 bc，他一直都没装，我就懒得继续了。

后面装了，说bc没装的是之前的输出

Re: [已解决]关于RTL8188GU芯片的USB无线网卡

编译完驱动，想转换USB模式该做什么？
我照着这个博客执行sudo usb_modeswitch -W  -v 0bda -p b711 -M失败，执行后常常卡着什么也不输出，有时输出usb_modeswitch的帮助页面。

Re: [已解决]关于RTL8188GU芯片的USB无线网卡

自然是因为插在电脑上的usb无线网卡被系统识别为u盘而非网卡

你一开始不是识别成网卡了吗？

Re: [已解决]关于RTL8188GU芯片的USB无线网卡

我的理解是：lsusb的输出后有个“After Modeswitch”，必须转换模式后才是网卡，况且我用iwd#device list后没有输出任何一个设备

是啊，有「After Modeswitch」，说明已经切换过了啊。

嗯……你的理解也有道理……那你搜一下你的网卡型号吧。我没有看到有用的信息。
