errors when connectin external USB 3.0 Harddsik

[copymaster]

Dear Members,

I updated to the latest Proxmox 3.1 Version and i am in the need to connect external USB 3.0 Harddisks for restoring a cluster.
But since the update the Harddsik is not mounted anymore.
there are several errors under dmesg:

usb 2-1: new high speed USB device number 2 using ehci_hcd

Google says this is a Kernel Bug (from fedora) but maybe this issue is already known?

What can i do to make the USB-Disk mount automatically again?

I am able to manually mount it via:

mount /dev/sdb1 <target>

but that is not the final plan.... it should mount automatically via UDEV-rules


Thank you
