Issue:

由于USB自动识别不太准确，使用我一般采用自定义DTS文件，但是发现：

当插入nvme和拔除nvme的时候，lspic获取到的sata控制的地址不一致

插入的时候 cat /sys/block/sata*/device/syno_block_info
pciepath=0000:00:1d.2,00.0

这就导致如果我拔除了nvme，就无法识别到sata硬盘。因为sata控制器的地址发生了变化。

同理qr下也会导致model无法固定。

特来求教如何有效锁定地址，而不受到nvme硬盘的影响。

你不热插拔 RR 不用管

但是USB自动识别的和物理机有点不一样，能否只定义部分内容。比如usb、sata、nvme三个地址只定义一部分？

已学习了dt文件的教程，已会操作dt文件的编写。
但是苦恼的是机器的nvme插槽插入或者不插入固态硬盘时候，sata控制器的pciepath会发生改变。
