小弟有一个USB HID设备，在vmware下运行正常，不过切换到真实的物理设备则无法使用。具体情况是：

1、dmesg信息对比vmware多了两行：
  1.   generic-usb 0003:096E:0202.0001: usb_submit_urb(ctrl) failed
  2.   generic-usb 0003:096E:0202.0001: timeout initializing reports
复制代码
2、用户态程序出错在：
  1. ioctl(4, USBDEVFS_REAPURBNDELAY or USBDEVFS_REAPURBNDELAY32, 0xbfd72bc8) = -1 EAGAIN
复制代码
小弟对usb驱动不太熟悉，请哪位大哥指个方向，该如何去判断解决故障呢？

附详细usb调试信息：

注意usb_submit_urb(ctrl) failed 这个错误，把Ehci-q.c 里的ehci_dbg打开，看看log
