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, depth=0, port_index=0, port_no=1, speed=3, usb_mode=0\r\r\n parent_dev=0xffffff0004233400, bus=0xffffff800105cc90, parent_hub=0, depth=0, port_index=0, port_no=1, speed=3, usb_mode=0\r\r\n adding unit addr=1, rev=200, class=9, subclass=0, protocol=1, maxpacket=64, len=8, speed=3\r\r\n setting config 0\r\r\n new dev (addr 1), udev=0xffffff00041b1000, parent_hub=0\r\r\n ugen0.1: at usbus0\r\r\n usb_probe_and_attach: enter\r\r\n iclass=9/0/0 iindex=0/0\r\r\n adding unit addr=1, rev=200, class=9, subclass=0, protocol=1, maxpacket=64, len=8, speed=3\r\r\n setting config 0\r\r\n new dev (addr 1), udev=0xffffff00020f9800, parent_hub=0\r\r\n ugen1.1: at usbus1\r\r\n usb_probe_and_attach: enter\r\r\n iclass=9/0/0 iindex=0/0\r\r\n parent_dev=0xffffff0004332100, bus=0xffffff800105cc90, parent_hub=0xffffff00020f9800, depth=1, port_index=0, port_no=1, speed=3, usb_mode=0\r\r\n adding unit addr=2, rev=200, class=0, subclass=0, protocol=0, maxpacket=64, len=8, speed=3\r\r\n setting config 0\r\r\n Root mount waiting for: usbus1\r\r\n Root mount waiting for: usbus1\r\r\n setting config 0\r\r\n Root mount waiting for: usbus1\r\r\n usb_alloc_device: Failure selecting configuration index 0:USB_ERR_TIMEOUT, port 1, addr 2 (ignored)\r\r\n new dev (addr 2), udev=0xffffff0004357800, parent_hub=0xffffff00020f9800\r\r\n ugen1.2: at usbus1\r\r\n usb_probe_and_attach: enter\r\r\n /dev/da0s1: No such file or directory\r\n Can you please guide me in resolving this issue?
