Thanks for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command 'uname -a' in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command 'dmesg > dmesg.log' and attach the resulting file 'dmesg.log' to this bug report.
3. Please run the command 'lspci -vvnn > lspci-vvnn.log' and attach the resulting file 'lspci-vvnn.log' to this bug report.
For your reference, the full description of procedures for kernel-related bug reports is available at http://wiki.ubuntu.com/DebuggingKernelProblems . Thanks in advance! |

Certain USB devices do not work properly, or do not work at all, while the ehci_hcd module is loaded.
A solution is to unload the ehci_hcd module, which is loaded every time the computer starts, using the command 'sudo modprobe -r ehci_hcd'. This works fine but unfortunatly ehci-hcd is necessary for using USB 2.0, so you lose USB 2.0 features.
Another solution is to disable USB 2.0 through the BIOS setup.
With some devices it is possible to read files normally (ie. copy files from an USB pendrive to the computer), but the device disconnects abrubtly when you start writing data on the device. In some devices it fails after writing a certain amount of data, probably the size of the write cache.
Steps to reproduce:
1. Insert your USB 2.0 device (like a flash drive)
2. If the device is recognised and mounted properly try copying a file to it.
3. Comfirm with the 'dmesg' command that it isn't functioning properly. (I/O errors etc)
4. Remove the USB device
5. Unload ehci_hcd with 'sudo modprobe -r ehci_hcd'
6. Insert your USB device again.
7. Check that everything works. (copy some files, etc.) |

description |
Certain USB devices do not work properly, or do not work at all, while the ehci_hcd module is loaded.
A solution is to unload the ehci_hcd module, which is loaded every time the computer starts, using the command 'sudo modprobe -r ehci_hcd'. This works fine but unfortunatly ehci-hcd is necessary for using USB 2.0, so you lose USB 2.0 features.
Another solution is to disable USB 2.0 through the BIOS setup.
With some devices it is possible to read files normally (ie. copy files from an USB pendrive to the computer), but the device disconnects abrubtly when you start writing data on the device. In some devices it fails after writing a certain amount of data, probably the size of the write cache.
Steps to reproduce:
1. Insert your USB 2.0 device (like a flash drive)
2. If the device is recognised and mounted properly try copying a file to it.
3. Comfirm with the 'dmesg' command that it isn't functioning properly. (I/O errors etc)
4. Remove the USB device
5. Unload ehci_hcd with 'sudo modprobe -r ehci_hcd'
6. Insert your USB device again.
7. Check that everything works. (copy some files, etc.) |

Hi Everyone,
The kernel in intrepid-proposed sounds promising. For anyone else interested in testing and giving their feedback, refer to https://wiki.ubuntu.com/Testing/EnableProposed .
Additionally, I haven't seen any specific comments that this exists in Jaunty, so I'm marking that task as Incomplete for now. |

Am taking the liberty of changing the status for intrepid as a fix has most certainly not been committed and I want to make sure this bug doesn't fall off the radar. |
