ONE removable device not mounting in Slackware w/ XFCE

Code:

Would it also help if I were to post the output of that command while my other player is connected? (The one which is recognized)- just for comparison?

No really as it might confuse the situation. Just the Cowon x9 MP3 player should be plugged in.
Plugging in the working one will just show a different driver and info only relevant to the working player which may
cloud/muddy the waters so to speak.

It may be useful to run this immediately after you plug it in:

Code:

dmesg | tail -n 25

Alrighty!

Here is the output of lsusb -t (First group=before player plugged in; second=after plugged in)

Code:

bash-4.2$ lsusb -t
/:  Bus 06.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/2p, 12M
/:  Bus 05.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/2p, 12M

bash-4.2$ lsusb-t

And here is the output of dmesg | tail -n 25

Code:

bash-4.2$ sudo dmesg | tail -n 25

Looks like the dmsg hit paydirt! It's listing the MP3 player [bolded].....now if I could just get it to connect!

Don't celebrate yet. It disconnected about 0.8 seconds after connecting.

What are the kernel versions on the 2 systems, 1 that works and the other (Slackware) that doesn't? Possibly there were kernel fixes for 'oddly' behaving USB devices, which are in one system and not another?

Yes, I noticed that disconnect. I was hoping maybe one of you guys would just come back with some simple command to reconnect!

The Slackware kernel I'm using is 3.10.17; Crunchbang kernel is 3.2.0-4-686.

If it was a kernel problem though, it likely wouldn't be mounting my other USB devices though, would it? (Remember, it works with all my other devices, just not this one particular MP3 player)

That disconnect message could be from a hardware fault (like a loose connection), but then you would likely see that on your other Linux too. It could be a problem with the USB drivers when talking to this device, but it seems unlikely the problem occurs in newer kernels and not older. Or it could be a software (firmware) problem within the device, that somehow interacts badly with this kernel and its USB drivers. But I think it is a waste of time to troubleshoot anything 'higher'. If it disconnected, and lsusb doesn't show it, Xfce certaining can't see it.

Some links for you:

Same X9 device, on crunchbang (which you say works), didn't work, then it did: http://crunchbang.org/forums/viewtopic.php?pid=261493

Try plugging in the player while it is on and playing music, and see if it stays connected: http://forums.gentoo.org/viewtopic-t-937874.html
