我正在尝试将 WSL 中的 GDB 连接到 Atmel SAMV71 Xplained Ultra 开发板。我在尝试让 OpenOCD 连接到开发板时遇到了问题。
我正在使用以下 OpenOCD 配置文件：
atmel_samv71_xplained_ultra_edbg.cfg
source [find interface/cmsis-dap.cfg]
source [find board/atmel_samv71_xplained_ultra.cfg]
source [find target/atsamv.cfg]
在 Windows 中使用 OpenOCD，我可以毫无问题地进行连接：

我正在进行的项目需要许多 Linux 工具才能轻松构建，因此我尝试通过 WSL 进行连接。我已按照说明使用USBIPD。
我正在使用 Windows 11，所以我认为不需要自定义内核：
$ uname -a

以下是udev我已经加载的规则（已用 检查和测试udevadm），并且我已确保我是 的成员plugdev：
60-openocd.规则

找到后这个帖子，我检查了一下，发现在中遇到了同样的错误dmesg：
$ dmesg| grep -i hid ⏎
[ 0.348324] usbcore: registered new interface driver usbhid
[ 0.348507] usbhid: USB HID core driver
[ 48.383257] hid-generic 0003:03EB:2111.0001: device has no listeners, quitting
我编译了一个自定义内核并CONFIG_USB_HIDDEV启动它并确保它正在运行：
$ dmesg| grep -i hid

但我从 OpenOCD 收到了同样的错误。
我还遗漏了什么？WSL 内核中还有许多其他与 USB HID 设备相关的配置选项。还有其他需要的吗？还有其他udev需要的规则吗？还有其他人使用 WSL 成功连接到此主板吗？
