linux上同时使用两块ft4232h模块，一共8个串口，怎么给8个串口改别名呢？

这是单独一块FT4232H的时候的rules文件内容，是可以成功的，两块的时候应该怎么写呢

zhihui@zhihui-MS-7B46:~$ udevadm info -a /dev/ttyUSB0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
