3250开发板链接划卡键盘有问题,请解惑
划卡键盘为大元752u。在Ubuntu及XP 下均能正常使用,在开发板上只亮灯,键盘不反应。
在Ubuntu下设备号如下: linux:/dev/input/by-id$ ls usb-413c_2003-event-kbd
设备ID等相关信息如下: linux:/dev/input/by-id$ lsusb Bus 002 Device 030: ID 413c:2003 Dell Computer Corp. Keyboard
链接上开发板后显示如下信息:
[root@zlg by-id]# usb 1-1: USB disconnect, address 11 usb 1-1: new full speed USB device using usb-ohci and address 12 usb 1-1: configuration #1 chosen from 1 choice input:
???????????????????????????????????????????????????????????????????????????????????????????????
?????????????????????????????? as /class/input/input11 input: USB
HID v1.10 Keyboard
[???????????????????????????????????????????????????????????????????????????????????????????????
?????????????????????????????1
开发板上设备ID为:
[root@zlg by-id]# ls usb-______________________________________________________________________________________________________________________________-event-kbd [root@zlg by-id]#
开发板上,插上VID为413c的Dell键盘,是可以正常工作的。
请大家看看问题出在什么地方,怎么改动一下?
