usb_alloc_device: Failure selecting configuration index 0:USB_ERR_TIMEOUT, port 1, addr 2 (ignored)

[Shah, Vishal]

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?

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