Hi, I use Slackware14.1.

And how I can solve this conflict?
Thanks!

Hi slackprogrammer and welcome to LQ.

Did you try to mount it manually?

Plug it in, wait 30 seconds tht it be ready, then type in a terminal:

Code:

cat /proc/partitions

and for instance if you find a partition on it named /dev/sdb1, just type as root:

Code:

mount /dev/sdb1 /mnt

to mount it on /mnt.

Thanks Didier Spaier for your answer. Yes, I have mounted it manually, but it responded nothing and can not end.After launching cairo-dock, I plug my USB External HardDrive, it shows:

brw------- 1 root root 8, 21 Nov 18 23:08 /dev/sdb5

and cannot mount it manually as root user.Whereas it shows like this before launching the cairo-dock.

then I don't know why this happens.

can you issue the following command after connecting.

Code:

dmesg

It might get another dev entry

hi slackprogrammer, can you see the following message in dmesg aswell?

xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called
> with disabled ep ffff8801fd2b0140

if so, you might have hit the USB kernel bug.
http://marc.info/?l=linux-usb&m=138005811528076&w=2

either wait untill this patch has been backported to 3.10.x and pat has included this.
or build a newer kernel 3.12
