sun 400，solaris10，一根usb连接线（就是能用usb口联网的那种），插上后/dev/usb目录
里能看到设备文件：
lrwxrwxrwx 1 root root 50 12 20 16:13 device0 -> ../../devices/pci@1e,600000/usb@a/device@1:usb_mid
lrwxrwxrwx 1 root root 50 12 21 16:02 device1 -> ../../devices/pci@1e,600000/usb@b/device@1:usb_mid
lrwxrwxrwx 1 root root 53 12 16 12:39 hid0 -> ../../devices/pci@1e,600000/usb@a/keyboard@1:keyboard
lrwxrwxrwx 1 root root 47 12 16 12:39 hid1 -> ../../devices/pci@1e,600000/usb@a/mouse@2:mouse
lrwxrwxrwx 1 root root 38 12 16 12:39 hub0 -> ../../devices/pci@1e,600000/usb@a:hubd
lrwxrwxrwx 1 root root 38 12 16 12:39 hub1 -> ../../devices/pci@1e,600000/usb@b:hubd

但在/var/adm/messages输出如下信息：

是不是实际上没有真正驱动起来啊？
如果usb通用驱动程序ugen能支持的话，怎么做才能把'interface'驱动起来？

谢谢！
