Did you try the fix in your second post?I searched for 5 mins and found 3 solutions that other people found.But in your post's you didn't list what you tried.
Do any people who are experts have anything they can say about this?

Wouldn't call my self an expert,but I have some time under my belt..........choose what you want... linux or the damn mp3 player.If you choose linux.........then get an mp3 player supported bye linux.If you choose the damn mp3 player then load up an os the supports it.........its really simple.


sorry if I seem grumpy,but I haven't had my coffee yet ;)

Ok,

yes I did try the fix in my second post,and that was about lowering the value of 'Max_sectors' to 64, which I explained in my last post.

I will try ndiswrapper, I can't believe I didn't think of that. I use that for my Vector Linux computer for a Wireless USB device, and it works perfectly. So yeh I'll give it a go for this.

Thankyou for your help guys.

Eddie

I will try ndiswrapper

As far as I know ndiswrapper is for wifi drivers.Unless they started something new.I looked in synatptics and found several mp3 player apps.You might have to enable the backports to see them.Also check this page out.

excuse me if i'm wrong, but is your mp3 player simply not mounting properly? or is there some other issue, because mounting stuff is a lot simpler than what it looks like you're doing...

It won't even get far enough to be able to mount it.

It will be visible to the computer at all, for about 6 seconds, in which time there is also a "connected to computer screen" on the player, before it becomes completely invisible to the computer, and on the players screen the connected screen goes away and it goes to charging.

I have researched though and apparently there is a flaw in the the linux kernel that makes a module called ehci_hcd interupt the USB 2.0 connections, so some USB devices won't work. I wasn't sure if this is the case with my MP4 player so I tried "sudo modprobe -r ehci_hcd", which disables that module. Apparently though, although that will stop the interference, USB 2.0 needs that module so USB 2.0 functionality will be lost with that disabled. So when I disable that I can see and access both partitions of my MP4 player and copy to them freely.
In the (Graphical) copying to window it tells me that the rate of transfer is on average 600KB/S, sometimes going up to around 800. This struck me as quite fast, but then again I haven't used USB in quite some time.

So is this connection only limited to USB 1.1?

Oh, also, once it was connected this way I tried changing the max_sectors thing again, as I can do it freely now, then re-enabling ehci_hcd, and re-plugging in the player, but absolutely no luck. It must purely be the ehci_hcd interference thing, I hope it's corrected in the new kernel...
