s3c2440 中使用usb转ps/2键盘问题！！

nishizawa23

我的是usb转两个ps/2接口，一个是接键盘，一个是接鼠标
插入usb有信息
usb 1-1: new low speed USB device using s3c2410-ohci and address 3
usb 1-1: configuration #1 chosen from 1 choice
input: Generic USB K/B as /class/input/input2
input,hidraw0: USB HID v1.10 Keyboard [Generic USB K/B] on usb-s3c24xx-1
input: Generic USB K/B as /class/input/input3

usb 1-1: New USB device strings: Mfr=0, Product=1, SerialNumber=0

在/dev/input下面出现
/dev/input # ls
event0  event1  mice    mouse0

使用命令hexdump -C mouse0
移动鼠标是有反应的

我想event1应该是键盘事件吧
hexdump -C event1

之后敲击键盘没有任何反应
但是hexdump -C event0时，不动鼠标和键盘，就一直出现数据，如下

我想敲击键盘，event1应该是有反应的，不知道是什么原因，是不是和内核配置有关系？有那位大侠知道？

今天试的时候，偶尔一次有成功，拔下来在插上去，又不能用了，是跟相关频率设置有关吗？

。。。问题解决了，换了个转接口就可以用了，看来是转接口的问题，貌似支持win和linux的转接口有区别的

好，不错不错

在ARM上一直都是用的USB的
