Description of problem: When attaching a certain USB mass storage device the following appears in the kernel log: kernel: usb 1-1: new high speed USB device using ehci_hcd and address 5 kernel: usb 1-1: configuration #1 chosen from 1 choice kernel: scsi7 : SCSI emulation for USB Mass Storage devices kernel: usb 1-1: New USB device found, idVendor=0dc4, idProduct=0073 kernel: usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 kernel: usb 1-1: Product: ATAPI-6 Bridge Controller kernel: usb 1-1: Manufacturer: Prolific Technology Inc. kernel: usb 1-1: SerialNumber: 9C0195 kernel: scsi 7:0:0:0: Direct-Access SAMSUNG HD400LD WQ10 PQ: 0 ANSI: 0 kernel: sd 7:0:0:0: [sdb] 781422769 512-byte hardware sectors (400088 MB) kernel: sd 7:0:0:0: [sdb] Write Protect is off kernel: sd 7:0:0:0: [sdb] Assuming drive cache: write through kernel: sd 7:0:0:0: [sdb] 781422769 512-byte hardware sectors (400088 MB) kernel: sd 7:0:0:0: [sdb] Write Protect is off kernel: sd 7:0:0:0: [sdb] Assuming drive cache: write through kernel: sdb: sdb1 kernel: sd 7:0:0:0: [sdb] Attached SCSI disk kernel: sd 7:0:0:0: Attached scsi generic sg1 type 0 kernel: sd 7:0:0:0: [sdb] Sense Key : No Sense [current] kernel: sd 7:0:0:0: [sdb] Add.

This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
