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

#SUBSYSTEMS=="usb", ENV{.LOCAL_ifNum}="$attr{bInterfaceNumber}"
#SUBSYSTEMS=="usb", KERNEL=="ttyUSB*", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6011", ATTRS{product}=="Quad RS232-HS", ENV{.LOCAL_ifNum}=="00",  SYMLINK+="ttl_port1", MODE="0777"

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.

    对于两块FT4232H的情况，需要在rules文件中新增规则，以确保每个设备都可以被正确识别和命名。以下是一个可能的解决方案： 
    # 第一块FT4232H
SUBSYSTEMS=="usb", KERNEL=="ttyUSB*", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6011", ATTRS{product}=="Quad RS232-HS", ENV{.LOCAL_ifNum}=="00", SYMLINK+="ttl_port1", MODE="0777"
SUBSYSTEMS=="usb-serial", KERNELS=="1-2.4.4:1.0", ATTRS{bInterfaceNumber}=="00", SYMLINK+="ttl_port1"
# 第二块FT4232H
SUBSYSTEMS=="usb", KERNEL=="ttyUSB*", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6011", ATTRS{product}=="Quad RS232-HS", ENV{.LOCAL_ifNum}=="01", SYMLINK+="ttl_port2", MODE="0777"
SUBSYSTEMS=="usb-serial", KERNELS=="1-2.4.4:1.1", ATTRS{bInterfaceNumber}=="01", SYMLINK+="ttl_port2"

    在这个例子中，我们为每块FT4232H新增了两条规则，在第一块设备的规则中，我们确保当bInterfaceNumber为00时，将其命名为ttl_port1；在第二块设备的规则中，我们确保当bInterfaceNumber为01时，将其命名为ttl_port2。通过这种方式，每块设备都可以被正确识别和命名。 请根据实际情况调整对应的idVendor、idProduct和bInterfaceNumber等参数，以确保匹配您的设备。
