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...
