Hi Folks,

since the update from 6.1 x86_64 to 6.2 x86_64 my external USB-HDs  are not 
any longer recognized automatically.

I mean that popup where I can mount/umount  the devices.

/var/log/messages says

Jan  4 10:37:28 server1 kernel: usb 1-7.3: new high speed USB device using 
ehci_hcd and address 15

What goes wrong here?

Thx
