Bill, I used to reload usb modules to get all these nasty errors out. Bit it was on sl5. On sl6, they seemed to be part of kernel and modprobe and company did not work for me. AZ -- Please excuse my brevity.

External USB HD is a Cavalry CAXM3701T0 Series 1 TB USB 2.0 / eSATA device. It worked fine with older linux SL (4.9) immediately after the SL6.0 error. It has worked in past on SL5.3 SL5.7. It worked on SL6 (same machine a week earlier). I automounted it, unmounted it, added a line to fstab and mounted at /mnt/usbhd</x>. /dev/sdb1 /mnt/usbhd</x> ext3 noauto,user,rw 0 0 This time (on SL6.1) when I get the messages, I had the fstab line uncommented and would have mounted it at /mnt/usbhd</x> except I got the hub port messages below and sdb didn't show up at all via fdisk.

Any advice on how to get this working without having to reboot, which I've not tried yet. Bill Lutter
