Description of problem: Whenever I plug in my usbdisk, FC4 will mount it twice: once on /media/usbdisk and once on /media/usbdisk1. Looking at /var/log/messages (attached), it seems it's the kernel who incorrectly sees it as two devices. Version-Release number of selected component (if applicable): kernel-smp-2.6.12-1.1398_FC4 How reproducible: Always

What is the claimed capacity of the disk? 128MB or 256MB? Also, please get me a usbmon trace (not sure if it captures the data with the number of LUNs, but it's worth trying). Here's how: mount -t debugfs none /sys/kernel/debug modprobe usbmon # Not really needed, but in case config is changed cat /sys/kernel/debug/usbmon/5t > /tmp/run.mon # insert here ^C Attach run.mon.
Created attachment 117320 [details] usbmon trace Here's the requested usbmon trace. The claimed capacity if the usbdisk is 128 MB.
Unfortunately, usbmon cannot get the needed information at present. This is the GetMaxLUN: f0cb8e00 2165649817 S Ci:002:00 -115 1 D f0cb8e00 2165651373 C Ci:002:00 0 1 D For the time being I suggest running with automatic mounting disabled (it's done in Removable Media properties panel)
What type of device is this btw ?
You mean the usbdrive? I don't really know: I got it from my company and it's got my company's logo on it, so not clear who the original vendor is.

We have a candidate patch, but I think for Fedora it's better to move it through upstream. I'm going to take care of it.
Mass update to all FC4 bugs: An update has been released (2.6.13-1.1526_FC4) which rebases to a new upstream kernel (2.6.13.2). As there were ~3500 changes upstream between this and the previous kernel, it's possible your bug has been fixed already. Please retest with this update, and update this bug if necessary. Thanks.
As another data point, the new kernel does NOT resolve this issue. I still get two devices sda and sdb created when I insert the USB Memory Stick. The stick I am testing with is only 32MB in capacity (the one Red Hat gives away in it's classes). My other difference is that I am NOT running the smp kernel, just the up one.
2.6.14-1.1637_FC4 has been released as an update for FC4. Please retest with this update, as a large amount of code has been changed in this release, which may have fixed your problem. Thank you.
Just upgraded last night to 2.6.14-1.1637_FC4 (not the smp one) on my laptop and still no joy. Kernel recognizes the USB memstick as sda1 and sdb1 which are then automounted by gnome..... Anything else I can provide to test?
Created attachment 121704 [details] /var/log/messages of two USB Memory Sticks Borrowed someone's 1GB USB Mem Stick and it only got automounted once (on 2.6.14-1.1644_FC4 kernel). Grabbed the one I have had the "problem" with and it still mounts twice. Attached the relevant /var/log/messages entries to see if it can help glean the difference and hence problem....
This is a mass-update to all currently open kernel bugs. A new kernel update has been released (Version: 2.6.15-1.1830_FC4) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. Thank you.
Still no joy. The stick that I have consistently tested with is still getting mounted twice. Let me know if there are any other specifics or information that I can do to help.
Robert, you need to attach some information with PID/VID so that I can blacklist the device. The /var/log/messages does not work for this purpose anymore. So, either /proc/bus/usb/devices, or a usbmon trace would do. Usbmon is better, it lets me see what actually happens. Chris's device is upstream since... 2.6.17 or so. It should be working fine by now.

I just tested and the stick is happy now (frankly hadn't used that stick in a while since it was so small).... I am now running 2.6.17-1.2174_FC5....
Ahh, so it was the same device as Christophe's after all. OK, closing the bug. Thanks for testing!
