Linux上的Logitech键盘，由于设备或资源繁忙而无法设置配置

Question

我有用于Linux的Logitech G613键盘。除了默认情况下G（1-6）键映射到F（1-6），并且没有重新映射F键就无法重新映射它们的方法，该方法工作正常。

因此，我浏览了Internet上的大量资源，并找到了g15daemon和libg15。不幸的是，libg15不支持G613，但是我通过添加以下行找到了一种方法来使库检测键盘

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

现在唯一的问题是，libg15使用来将kernerl驱动程序与设备分离usb_detach_kernel_driver_np()，这是成功的。但是之后，对的调用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

在分离内核驱动程序之后

同样，一旦分离了驱动程序，键盘也会停止运行。必须重新连接才能正常工作。

谁能帮我理解为什么usb_set_configuration()失败了吗？
