一个usb转串口在ubuntu7。10下用不了，但是在suse10.2和fc7下没有问题

一个笔记本以前没事用的是suse10.2用这个usb转串口很稳定。但是我前几天换成了ubuntu7.10，原来能用的现在却用不了了

我要用串口调试硬件，这可如何是好

这传信息说明已经可以用啦

问题解决了，可能是驱动有问题.看信息是可用，但是在最后有一个ftdi_sio 3-2:1.0: device disconnected在／dev下根本没有ttyUSB这个设备,后来用这两个命令解决了
sudo apt-get remove brltty
sudo aptitude reinstall udev
然后重启了一下就能识别了
