当我通过 USB2.0 端口将 PreSonus USB AudioBox 96 连接到 Ubuntu 18.04LTS 桌面时，
dmesg循环显示以下错误：

我怀疑故障发生在这Linux 内核的行。
该接口间歇性地可用作 中的输入源alsamixer。它会持续几秒钟，然后消失、重新出现等。该设备在我的 Windows 计算机上运行良好。
有人对如何调试/解决这个问题有任何建议吗？
我已经包含了下面的输出lsusb -v。

答案1
我在 Mint 20 中遇到了几乎相同的问题。通过将其插入 USB 3.0 而不是 2.0 解决了这个问题
答案2
据我所知，这是一个驱动程序问题，如果没有代码干预就无法解决。以LKLM Line6产品的问题为例：
