 |
|
Hi
I have some problems with UDEV and my iRiver H320:
When I start my system and plug device to USB port I get in dmesg:
| Code: | [ 383.709888] usb 1-5: new high speed USB device using ehci_hcd and address 6
[ 383.877633] scsi5 : SCSI emulation for USB Mass Storage devices

[ 388.945925] Attached scsi disk sdb at scsi5, channel 0, id 0, lun 0
[ 388.946888] usb-storage: device scan complete
|
But there is no new device in /dev such as sdb or sdb1!
I found strange think - when I do emerge --oneshot udev and plug device after that emerge i get the same info i dmesg but also new device in /dev !
I'm looking for help to resolve this strange UDEV bhavior!
Thanks in advance lukas

Try setting RC_DEVICE_TARBALL="no" in /etc/conf.d/rc
Else UDEV is using the devices of the last running system. Which can be confusing. |

I have RC_DEVICE_TARBALL="no" already in my /etc/conf.d/rc
But what about UDEV is using the devices of last running system ? |

I posted a possible reason there.
What I meant was that at shutdown makes a snapshot of everything in /dev so you can keep your hand generated devices if this option is "yes". If udev works properly for you, you will have less problems when deactivating this option, as the /dev tree will be built with only the currently active hardware. |

| it doesn't metter when RC_DEVICE_TARBALL is set to "yes" or "no" cause UDEV simply don't work in this two cases I have to run manually udevstart while something is plugged to USB to have a proper device created in /dev |
