接USB键盘正常，接一个USB的扫码枪就不正常了

理论上USB键盘和扫码枪是一个东西。

这个当一扫码时，扫码枪先发一个8字节包，其中第2个字节是控制大小写的，即0x39，然后收到这个后自动回复

if( keybufdata[0x02] == 0x39 )

{

endp0outdata[ 0 ] ^= 0x02;

lockflag = 1;

}，就在自动回复的代码中返回了0x2a错误

错误码如下：#define ERR_USB_TRANSFER 0x20

用的是【\HOST_KM】示例，没有做任何修改，USB HS/FS都试了，都有这个问题，

紧急求救，之前一直用键盘试，感觉没问题，谁知道插这个扫码枪就出现此毛病。
