 |
|
Hello, folks!
Got myself Cowon X9 player couple of days ago. And all this time I'm trying to get it connected and mounted on my Gentoo puter. The fact number 1: it works perfectly in WinXP in same port it isn't in Linux, fact number 2: it works fine and can be mounted on some Linux machines to, fact number 3 (unbelievable!) I've got it once mounted on my Gentoo box (that's how some music got there). The particular USB port is working as flashdrives and extended HDD work fine in Gentoo.
After some investigation I've figured out that on Linux boxes, that are able to mount my new toy lsusb -v gives you:

But on my box lsusb gives nothing about Cowon devices. Instead I get this in my dmesg:

| Heh, found another strange thing. If player is on and playing music it recognized (actually, not dropped after been recognized) correctly and can be mounted, if it paused, it will be dropped. Strange! |
