Linux上的Logitech键盘,由于设备或资源繁忙而无法设置配置

我有一个用于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,效果很好。

因此,我浏览了Internet上的大量资源,并找到了 g15daemon 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使库能够检测键盘的方法

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

现在唯一的问题是, libg15 使用usb_detach_kernel_driver_np()将kernerl驱动程序与设备分离,此操作成功。但是之后,对usb_set_configuration()的调用失败了,

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

hwinfo的输出,在分离内核驱动程序之前

以及分离内核驱动程序后

此外,一旦驱动程序被卸下,键盘也会停止运行。必须重新连接才能正常工作。

有人可以帮助我了解为什么usb_set_configuration()失败的原因吗?
