Hi all,

Can anyone tell me what the usb hotplug problem is that my system is struggling with while it starts up ethernet at boot time? My post-boot /var/log/messages is down below. See the recurring chunks like this:

Oct 26 18:26:52 linux kernel: usb-uhci.c: ENXIO 80000380, flags 0, urb c61e23e0, burb c61e24e0
Oct 26 18:26:52 linux kernel: usbdevfs: USBDEVFS_CONTROL failed dev 3 rqt 128 rq 6 len 103 ret -6
Oct 26 18:26:52 linux /etc/hotplug/usb.agent[969]: cannot get config descriptor 0, No such device or address (6)

This is my home system and is networked through a USB cable modem ethernet adapter to my ISP. A printer is on anther USB port. Both devices are configured as hotplugged. The problem is not serious. The network normally starts up in about 5 seconds and everything works, but I'd like to understand what the snag is and fix it.
