Red Hat Bugzilla – Bug 479027
usb 1-1: device not accepting address NN, error -71
Last modified: 2015-01-19 07:43:13 EST
Description of problem: My USB hub is no longer recognized as USB 2.0 device, but downgraded to 1.1 automatically. So writing e.g. to an SD card never ends. /var/log/messages prints zillions of these kernel error messages after connecting the USB hub to any USB 2.0 port: Jan 6 16:36:28 bernd kernel: usb 1-1: new high speed USB device using ehci_hcd and address 20 Jan 6 16:36:28 bernd kernel: usb 1-1: device descriptor read/64, error -71 Jan 6 16:36:29 bernd kernel: usb 1-1: device not accepting address 21, error -71 ... Finally, the device is connected but runs at 1.1 speed: Jan 6 16:36:32 bernd kernel: hub 1-0:1.0: unable to enumerate USB device on port 1 Jan 6 16:36:32 bernd kernel: usb 2-1: new full speed USB device using ohci_hcd and address 3 Jan 6 16:36:32 bernd kernel: usb 2-1: not running at top speed; connect to a high speed hub Jan 6 16:36:32 bernd kernel: usb 2-1: configuration #1 chosen from 1 choice Jan 6 16:36:32 bernd kernel: scsi5 : SCSI emulation for USB Mass Storage devices Jan 6 16:36:32 bernd kernel: usb 2-1: New USB device found, idVendor=058f, idProduct=6377 Jan 6 16:36:32 bernd kernel: usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Jan 6 16:36:32 bernd kernel: usb 2-1: Product: Mass Storage Device Jan 6 16:36:32 bernd kernel: usb 2-1: Manufacturer: Generic Jan 6 16:36:37 bernd kernel: scsi 5:0:0:0: Direct-Access Generic USB SD Reader 1.00 PQ: 0 ANSI: 0 Jan 6 16:36:37 bernd kernel: sd 5:0:0:0: [sdb] Attached SCSI removable disk Jan 6 16:36:37 bernd kernel: sd 5:0:0:0: Attached scsi generic sg3 type 0 The device works without any errors under Fedora Core 5,6,7 (Kernel 2.6.20) on the same hardware. The device works without any problems under Windows 2000 or XP on the same hardware. Same error in Ubuntu 8.10 BTW. Tried all 2.6.27.7,8,9 kernels but no change. Version-Release number of selected component (if applicable): Kernel 2.6.27.7|8|9 How reproducible: Install this device on any Fedora 10 machine: ID 058f:6377 Alcor Micro Corp. Multimedia Card Reader Steps to Reproduce: 1. Attach USB hub to USB 2.0 port. 2. tail -f /var/log/messages Actual results: Most USB hubs no longer working under Fedora 10 (last known version to run was Fedora 7). Checked with other Alcor and Kingston hubs, same or similar problems. No problems under Windows 2000 or XP. Expected results: Device running at USB 2.0 speed without any errors in the log files. Additional info: Is this a kernel bug?
Checked today with FC7 and Kernel 2.6.21 again - device works perfectly, so the problem was introduced between linux 2.6.22 and 2.6.27. Will test with FC8 and other kernels in the next days, maybe we can find out more.
I see "works on the same hardware" in the original report, but I saw hardware failing during installation before, so it may be a failure of the Host Controller (HC). The key is to get two kernels (old - working, and new - broken) onto the same box. Usually it's easier to take an old userland, like F-9 and install an F-10 kernel on it with just rpm, or rpm --force. Then it's only one reboot to get back to old kernel. Once there, I'll need two usbmon traces from the old and new.
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.
