 Posted: Sat Jul 14, 2007 11:29 am Post subject: odys mp3 player: no device node, other USB devices [SOLVED] |
 |
|
Hi,
I am fighting to get to work a MP3 player "odys S-4". Other USB memorysticks are mounted by HAL, when I plug them in.
I know the device worked some months ago (when I was using a different motherboard/cpu).
I use Linux 2.6.22-gentoo-r1 together with udev-113-r2. I have also tried the last stable linux-kernel and
the last stable udev version, but without no luck.
The devices seems to get recognized for about a second and then it gets removed again.
As no device node is given to the device, I can't mount it.
I appreciate any help. Thanks
Here is the output of udevinfo -a -p /devices/pci0000:00/0000:00:02.0/usb2/2-1
| Code: |
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

I have somehow solved the problem. At the moment I think it is a kernel bug.
The odys mp3 player only gets mounted, when the module ohci_hcd is the
only USB related kernelmodule (ehci_hcd) or is modprobed after the ehci_hcd
module.
If both modules are loaded with the help of udev while booting the device does
not get recognized. |
