Hi All,

 

This is regarding the issue we are seeing in the FreeBSD 8 USB driver. I
have a USB flash device from which the system is booted. Occasionally
USB device fails to get initialized in the system. So I enabled
USB_DEBUG option and added few more printfs for debugging purpose. After
multiple iterations of rebooting I am able to reproduce the issue and I
see following messages on console while booting the system. Have any
similar issue been reported previously? 

  

parent_dev=0xffffff0004208300, bus=0xffffff8001053c90, parent_hub=0,

Can you please guide me in resolving this issue?  Thanks in advance.

 

Thanks,

Vishal
