有台光谱仪在桌面Ubuntu下可以连接，并且能读出数据但是树莓派上连接不上。求助。。。
这台仪器的说明文档里for linux 用户的步骤：
perform the following steps.
- Copy the file 10-oceanoptics.rules from the "drivers" directory into /etc/udev/rules.d
- restart udev. On Fedora and similar linux distros, you can restart
udev with the following commands:
udevcontrol reload_rules
udevstart
If this does not successfully restart udev, you will need to reboot.
- Make certain the "libusb" library has been installed on your system. It should be a relatively recent
version of the library. You can use the "apt" utility to check if it has been installed.
我在Ubuntu上按照上面的步骤复制.rules到rules.d文件夹然后执行重启udev给出的两条指令的时候出错但是重启以后就连接上了。
树莓派上是raspibian，所有的步骤跟在ubuntu上一样。是不是raspibian上udev要设置一下呢？还是下面一步没有libusb库呢？这个该如何查看，本人实在是linux菜鸟，windows上移植java才开始接触linux。
