Hi All,
AT boot time, with usb flash drive plugged in, I have the following report in /var/log/dmesg | Code: | [ 7.467568] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
[ 7.469261] ACPI: PCI Interrupt Link [LNKU] enabled at IRQ 10
[ 7.469279] PCI: setting IRQ 10 as level-triggered

[ 13.998124] ohci_hcd: probe of 0000:00:02.0 failed with error -16 |
My problem occurs at the second code section.
I tried as many timer options I could find in kernel configuration, without any improvement.
On the other side, the install iso does raise such an issue, and flash disk is declared, visible and operational as /dev/sda. So I figure it could be a good starting point for my kernel configuration.
I dont know how to retrieve the .config matching the iso kernel configuration.
Does someone has any advice in this respect ?
Thank you for your attention. |

you can boot the iso cd and type this:
| Code: | | zcat /proc/config.gz |
This will output the current running kernel's config.
If you've mounted a local disk you can redirect this output to a file |

Hi,
I finally solved that out, but because it occured during a kernel leaning process, I'll have to finish it prior to posting any of my conclusion on the minimalistic was to solve this USB flash disk issue.
Richard , thanks again for this great tip  ,
I shouldn't be too long to close this topic.  |
