如何找尋觸控面板裝置路徑? - Linux

在原廠驅動程式中所附的readme文件第四步驟為


d. Add the a new "InputDevice" Section as the following.

Section "InputDevice"
Identifier "HID TOUCH"
Driver "xfhiddrv"
Option "Device" "/dev/usb/hiddev0"
Option "ScreenNo" "0"
Option "Rotation" "0"
Option "SwapY" "0"
Option "UpSound" "0"
Option "DownSound" "0"
EndSection

In the item of "Device", you must depend on your computer. So, it can be
the value,
such as the followings.
"/dev/usb/hiddevx" x=0,1,..2, n

先說明一我的硬體
我是用Toshiba 3490ct的老筆電
觸控面板的控制器是裝在外接usbhub上
使用Lubuntu10.04

照他所寫的/dev/底下我沒看到/usb/的資料夾
我自己判斷是在/dev/bus/usb/001/的資料夾內
裡面有001 002 004 005四個屬性為"字元裝置"的檔案
lsusb指令的結果為

Bus 001 Device 005: ID 04d9:0499 Holtek Semiconductor, Inc.
Bus 001 Device 004: ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen
Bus 001 Device 002: ID 058f:9254 Alcor Micro Corp. Hub
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

所以我將那行輸入為
Option "Device" "/dev/bus/001/004"

但是在執行的時候卻顯示
Can't find a touch screendevice not exist on /dev/bus/usb/001/004

請問有可能是哪一部分出問題?
先謝謝各位先進的回答了!
