我有一个用于 linux 的 Logitech G613 键盘。它工作正常，除了 G(1-6) 键默认映射到 F(1-6) 并且没有重新映射 F 键就无法重新映射它们。

所以，我在互联网上浏览了很多资源，找到了 g15daemon和libg15。不幸的是，libg15不支持 G613，但我找到了一种方法让库通过添加以下行来检测我的键盘

DEVICE("Logitech G613",0x46d,0xc53d,G15_KEYS),

现在唯一的问题是，libg15将内核驱动程序与设备分离usb_detach_kernel_driver_np()，这是成功的。但在那之后，调用usb_set_configuration()失败了

USB error: could not set config 1: Device or resource busy

hwinfo分离内核驱动程序之前的输出

并在分离内核驱动程序后

此外，一旦驱动程序被分离，键盘将停止工作。它必须重新连接才能正常工作。

谁能帮我理解为什么usb_set_configuration()会失败？
