From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 Description of problem: When trying to use the external USB 2.0 enclosure Genesys Logic, Inc. USB 2.0 IDE Adapter several access and I/O problems occur, while the USB 2.0 support for this device works perfectly. While using the USB 2.0 support it detects that the PCI: cache line size of 128 is not supported by device so it adjusts itself while using both ohci-hcd, uhci-hcd USB 1.1 suport it does not. When using the ohci-hcd, uhci-hcd module it is possible to mount the device without any error message. But when trying to access any of the files on the external USB drive it is not possible to do so giving several I/O errors after a while. The drive can not be mounted again saying that the device can not be found unless by doing a reboot, then the device can be mounted again. Version-Release number of selected component (if applicable): kernel-2.6.6-1.435.2.3 How reproducible: Always Steps to Reproduce: 1. mount device with ohci-hcd or uhci-hcd module loaded 2. access file on device (for example copy or read a file) 3. the copy/read process stops giving I/O errors 4. can not remount the device Actual Results: Not possible to use USB 1.1 capability (ohci-hcd, uhci-hcd) Expected Results: Usage of USB 1.1 capability Additional info: Jul 6 19:19:17 gateway kernel: scsi3 : SCSI emulation for USB Mass Storage devices Jul 6 19:19:17 gateway kernel: Vendor: Genesys Model: USB to IDE Disk Rev: 0002 Jul 6 19:19:17 gateway kernel: Type: Direct-Access ANSI SCSI revision: 02 Jul 6 19:19:17 gateway kernel: SCSI device sda: 78140160 512-byte hdwr sectors (40008 MB) Jul 6 19:19:17 gateway kernel: sda: assuming Write Enabled Jul 6 19:19:17 gateway kernel: sda: assuming drive cache: write through Jul 6 19:19:17 gateway kernel: sda: sda1 sda2 Jul 6 19:19:17 gateway kernel: Attached scsi removable disk sda at scsi3, channel 0, id 0, lun 0 Jul 6 19:19:17 gateway kernel: Attached scsi generic sg0 at scsi3, channel 0, id 0, lun 0, type 0 Jul 6 19:19:17 gateway kernel: USB Mass Storage device found at 2 Jul 6 19:19:17 gateway kernel: updfstab: Using deprecated /dev/sg mechanism instead of SG_IO on the actual device Jul 6 19:19:18 gateway scsi.agent[4135]: disk at /devices/pci0000:00/0000:00:1d.2/usb3/3-1/3-1:1.0/host3/3:0:0:0 Jul 6 19:22:17 gateway kernel: usb 3-1: reset full speed USB device using address 2 Jul 6 19:22:22 gateway kernel: usb 3-1: control timeout on ep0out Jul 6 19:22:27 gateway kernel: usb 3-1: control timeout on ep0out Jul 6 19:22:28 gateway kernel: usb 3-1: device not accepting address 2, error -110 Jul 6 19:22:28 gateway kernel: scsi: Device offlined -

If you try a kernel from one of the following sources, does the problem still occur? + rawhide (a.k.a. FC-devel) + FC 3 test 1 + http://people.redhat.com/arjanv/2.6/
After trying all the above kernel sugestions the problem still remains, taking the drive a little bit longer to go offline and giving I/O errors.
Applying the suggestion from bit (bit_char_g) regarding bug# 122522 ( Comment #2 ) to the latest FC2 kernel 2.6.6-1.435.2.3 resolves the issue for both ohci-hcd, uhci-hcd.
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
