Hi

I am using Gentoo (gentoo-dev-sources-2.6.8-r3). Today, I switched from compatible ATA-mode to native S-ATA (my harddisc was /dev/hdc, now is /dev/sda). But now, USB mass storage does not work anymore. Here is, what I got in messages (debugging enabled):

Without using native S-ATA, the device gets detected and configured as /dev/sda.

Thanks for help,

Well the usb storage will be /dev/sdb now, at least it is on mine when I changed to sata. Did you change your fstab entry for the device to /dev/sdbx? With the device connected try running:

# fdisk -l /dev/sdb

and see if the device partitions are picked up on sdb. Also, post your fstab.

fdisk -l /dev/sdb does not show anything as the device does not exist at all (see /var/log/message output above). It is definitely not a FS or partition related problem but actually a kernel problem. The device will not be created when the system detects it.

Here my fstab:

/dev/sda1 /boot ext2 noatime 1 2
/dev/sda3 / reiserfs noatime 0 1
/dev/sda2 none swap sw 0 0
/dev/sda4 /home reiserfs noatime 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
/dev/sdb1 /mnt/camera auto noauto,user 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
none /proc/bus/usb usbfs defaults 0 0

Should be fine.

I will check my kernel config again. But thank you for more ideas where to look at.

Daniel

anything on this? I have exactly the same problem
