Friday, on a desktop running SL 6.1, I tried mounting an external USB hard drive and got hub port status errors.
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
