大虾留步，急死了！！！

我用sl811给我的arm扩展了一个usb主接口，现在想通过usb连接一个usb无线网卡，操作系统是uclinux，可是当激活无线网卡时要有数据和sl811交互，结果发生一下问题：
SOF interrupt: td_array->len = 0x1, s/b: 0
INTERRUPT URB:[ 3e6] dev: 2,ep: 0-O,type:CTRL,flags:   0,len:0/0,stat:-115(fffff
f8d)
hc_simple.h: cmd(8): 02 01 00 00 81 00 00 00
SOF interrupt: td_array->len = 0x1, s/b: 0

hc_simple.h: data(0/3000): stat:-115
IRQ occurred while service SOF: irq = 0x1
IRQ occurred while service SOF: irq = 0x1
IRQ occurred while service SOF: irq = 0x1

请问各位大虾这是什么原因呢，万分感谢！！！！！

没人遇到这种情况吗，郁闷ing.............
