[toni_uk]

I have a problem with my USB connections. for some resons they are not quite doing what they should. I have a new camera and on my old laptop (running Ubuntu 8.04) it is deteted immediately on the old USB 1.0. On my brand new PC also running Ubuntu 8.04 it is not detected. dmesg is showing the following:

[ 563.332000] end_request: I/O error, dev sdb, sector 60796 [ 563.332000] printk: 24 messages suppressed.

Any help appreciated - don't quite understand why it is not working. Thanks!

Did you ever solve this problem? I'm trying to help someone with the same issue. I think it comes down to disabling CONFIG_USB_SUSPEND, which can be done by reloading the module "usbcore" with the option "autosuspend=-1." However doing that is tricky because it's hard to unload usbcore once the system is booted.

There are instructions here on other ways to disable CONFIG_USB_SUSPEND without reloading usbcore. Have you tried them? I don't want to try them myself I can't break my computer right now, and it's hard to test USB stuff in a virtual machine.

Debian / Ubuntu systems: ======================== Comes with usbcore (CONFIG_USB) compiled as a module and CONFIG_USB_SUSPEND enabled (at least on Ubuntu). Therefore, to disable autosuspend you either: - recompile kernel without CONFIG_USB_SUSPEND - configure /etc/modprobe.d/ with a file containing "options usbcore autosuspend=-1" or set to 0 depending on your kernel If your system needs the modprobe configuration file above, and if your system uses initrd (probably does) then you will need to rebuild the initrd for your kernel for this to take effect. For example: dpkg-reconfigure linux-image-2.6.22.1

I have the same problem. With a camera

I tried the modprobe thing, but it did solve the problem

pytheas22: thanks. sorted it, can't remember how though. Thanks anyway - good to see that someone is looking through all the unanswered threads.

Do you have any idea how you fixed it? At least, do you remember if CONFIG_USB_SUSPEND had anything to do with it?

I'm sorry no one answered your post earlier, too. It's a good example of why looking through unanswered posts is a good way to kill time when you're bored.

hey guys, just put a clean install of Ubuntu back on my computer and of course had the same problem with the USB/Camera. Did a bit of research and found this so damn easy solution on the Mint Forum:

in the terminal type: echo -1 >/sys/module/usbcore/parameters/autosuspend

I was logged in as root - not sure whether necessary. Then just reboot and Bob's your Uncle.

Worked a treat for me.

I tried this fix for the same error message with a different error number (-110), but it did not seem to have any effect.

Thanks,

What is the total output of 'dmesg | tail' after you plug in the device?

Did you try this:

In short as root:
echo Y > /sys/module/usbcore/parameters/old_scheme_first
