Description Marcus Schneider 2009-09-09 07:10:17 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; de; rv:1.9.1.2) Gecko/20090730 SUSE/3.5.2-3.2 Firefox/3.5.2

Whenever I attach an USB device to the running system, it will not be shown in KDE's "newly added devices" taskbar applet, dmesg shows that it is found, manual mounting even as root does not work, as no device node is created.

Here is dmesg:

Now trying to mount /dev/sdb1 on some arbitrary mountpoint, system claims that the "special device /deb/sdb1" does not exist.

Having the device plugged in at system startup is no issue, device is recognized, device node created and mounting works like a charm.

This affects all USB devices, not only the one from above.

with 11.1 everything worked like charm...

Reproducible: Always

Steps to Reproduce:
1. Have recent factory
2. Start system
3. Plug In USB device

Comment 1 Marcus Schneider 2009-09-09 07:34:39 UTC

Note: this only applies to the 2.6.31-rc8 desktop kernel, not the 2.6.31-rc7-rt8 realtime kernel

Comment 2 Greg Kroah-Hartman 2009-09-09 12:51:37 UTC

Known bug, fixed in 2.6.31-rc9

Comment 3 Zachary Klein 2009-10-03 18:19:44 UTC

This bug still affects me on Milestone 8
