I have two Debian Squeeze systems both using the same kernel: Linux dragon 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 x86_64 GNU/Linux
One system connects a usb hard drive, the other does not although in the past it did. Both systems will connect to usb flash drives and to a usb San Disk mp3 drive. A more complete description of the situation is as follows: Some months ago I purchase a Toshiba 640 Gb usb hard drive and successfully used it to backup an internal drive on my Debian Squeeze system. Shortly after the backup the system could no longer connect to the usb drive. A second system running Debian Lenny had no problem connecting to the usb drive. I assumed something had changed in the Squeeze system as I run regurlar dist-upgrades. Last week I upgraded the second system from Lenny to Squeeze. It still has no problem connecting to the usb drive. My intention is to upgrade the primary system from Squeeze to Wheezy but I have not done so yet. Summary: I have two fully upgraded Squeeze systems one of which can connect the usb drive and one of which cannot although in the past both could make the connection. What could have changed? For the record here is a sample of the connection failure: May 22 10:31:05 dragon kernel: [ 4306.496515] usb 1-2: new high speed USB device using ehci_hcd and address 29 May 22 10:31:05 dragon kernel: [ 4306.644021] hub 1-0:1.0: unable to enumerate USB device on port 2 May 22 10:31:05 dragon kernel: [ 4306.912017] usb 1-2: new high speed USB device using ehci_hcd and address 30 May 22 10:31:05 dragon kernel: [ 4307.060020] hub 1-0:1.0: unable to enumerate USB device on port 2 May 22 10:31:06 dragon kernel: [ 4307.328518] usb 1-2: new high speed USB device using ehci_hcd and address 31 May 22 10:31:06 dragon kernel: [ 4307.476021] hub 1-0:1.0: unable to enumerate USB device on port 2 May 22 10:31:06 dragon kernel: [ 4307.744017] usb 1-2: new high speed USB device using ehci_hcd and address 32 May 22 10:31:06 dragon kernel: [ 4307.892520] hub 1-0:1.0: unable to enumerate USB device on port 2 May 22 10:31:06 dragon kernel: [ 4308.160016] usb 1-2: new high speed USB device using ehci_hcd and address 33 May 22 10:31:07 dragon kernel: [ 4308.308519] hub 1-0:1.0: unable to enumerate USB device on port 2 -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
