Problem with hot plugging usb flash disk

I am running Ubuntu 8.10. Ubuntu doesn't see my usb flash disk when I plug it in after booting up. The only time it sees it is if I go to TERMINAL and type in lsusb. I have to do this 2 to 3 times before it sees it. Copying files from the flash disk to my laptop then takes ages. A 70mb folder took approx 40 minutes to copy. Can anyone help? I am using a Fujitsu Siemens laptop with dual boot. The usb disk works fine in windows XP. Could this be a driver issue?

I would look at what goes on in the system when you plug the flash drive in..
open a terminal and type the following command, then plug in the drive and see if any errors pop up. You should see the system detect the drive, load the driver, and assign the device id


tail -f /var/log/messages

here is an example output..
Code:
it-lenny:~# tail -f /var/log/messages

Err that certainly doesn't look right.. Nothing like the working example I showed..

I see this was a known bug in Ubuntu LTS.. I wonder if they ignored it ?
https://bugs.launchpad.net/ubuntu/+s....17/+bug/53972

try doing the following command before plugging in the device..
modprobe -r ehci_hcd
And watch that message log again when you plug the device in..

Read the following thread and try some of the fixes like the acpi=noirq in post number 8

Glad to hear you got it sorted out, even if it did require different hardware

Another USB Problem!!
Thanks for the help!. I have another problem with my Seagate USB 250GB HDD. I get the following message:

Unable to mount FreeAgent Drive

DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply.
Possible causes include: the remote application did not send a reply,
the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

This is on my Fujitsu Siemens laptop booting up with the drive plugged in. Running Ubuntu 8.10. The drive works fine in Windoze. When I go to "Places" I can see the drive as "FreeAgent Drive". Any ideas?? Looks like Ubuntu 8.10 does not like USB devices!!

Seagate Free Agent external USB Drive.. When originally released Seagate stated these drives are for Windows only and are not compatible with Linux.. You sure know how to pick em On the brighter side Linux folk hate being told NO..

someone figured out a workaround to the drive sleep issue.. http://alienghic.livejournal.com/382903.html
If the drive decides to go to sleep on you and not wake up you will need to apply that workaround.


another item, the one that is probably causing your current issue, is the drive is formatted as NTFS by default, so you would need to install the ntfs-3g driver on your system so it can mount the drive, and be able to read and write to it.
sudo apt-get install libfuse2 fuse-utils ntfs-3g

http://www.ntfs-3g.org/manual.html

Really appreciate the help! The drive that I have is a solid state drive - no whirring disk. Anyway I installed the ntfs drive - no difference. Hung up my machine the first time I re-booted. Still get the same message when I try to open up the drive. By the way, I bought this drive a couple of months before I installed Ubuntu. Whatever I buy now, I first check for Linux compatability!!

Do you have a link to the drive specifications somewhere so we can see what it is ? or the exact model number at least ?
