Note that this is annoying, not much more :) I have *EXACTLY* the same situation, and I figured out what was causing it, and I came up with with a workaround; I wouldn't call it a perfect solution. - My old, emergency backup machine is a 1999 Dell PIII, 450 mhz, with 128 megs of RAM, and USB 1.1 hardware. According to dmesg, the ehci_hcd code aborts at bootup, and only the ohci_hcd code runs. All my USB1 and USB2 devices run OK. Mind you, at USB 1.1 speeds, maybe I should say they *CRAWL* OK. The auto option for filesystem type works OK in both the mount command and in /etc/fstab. I could get away with an fstab entry like... /dev/sdb1 /mnt/external auto noauto,user,noatime,notail 0 0 and simply mount /mnt/external, regardless of what I hooked up to the USB port. - My relatively new AMD64 (in 32-bit mode) has USB2 hardware. I built both ohci_ocd ehci_ocd into the kernel. I experienced the following symptoms... - USB1 devices were totally flakey, sometimes they would show up as /dev/sdb1, and sometimes they wouldn't. When it didn't show up... However, if I open a shell, fdisk the device, quit fdisk and close the shell, I can mount the card... would usually work, but not always. - USB2 devices would show up OK, and run at USB2 speeds, but auto would *NOT* work as a filesystem type with either /etc/fstab or the mount command After a lot of screwing around I came up with the following workaround. - build ohci_hcd into the kernel - build ehci_hcd as a module. Do *NOT* auto-load the ehci_hcd module. - write local udev rules to generate symlinks for my USB devices. /etc/fstab has entries that mount the symlinks, and those entries specify the filesystem type. I use msdos for my camera's memory cards, vfat for my mp3 player, and reiserfs for my backup drives. Run in USB1.1 mode most of the time. When I'm backing up my hard drive to a USB2 drive, and I want the extra speed, I run the commands modprobe ehci_ocd udevstart ...before I plug in the backup drive. When I'm finished, and have removed the backup drive, I run the commands rmmod ehci_ocd udevstart ...and I'm back to where I was before. It's not perfect, but it works. -- Walter Dnes [EMAIL PROTECTED] In linux /sbin/init is Job #1 My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list

(...) Thanks a lot for your report. I'll check what I did, I don't remember if I compiled the drivers as modules or not. It's interresting that you also have an AMD64 board. I run a Tyan Tiger K8W. Maybe this has to do with some chipset? Or is it Gentoo-based? I'll test the new SuSE when it is released and then I have some comparison.

Hello Ognjen and thanks for your suggestion. I'm ashamed it really was that simple. I just thought usb-storage was loaded, I was wrong. i only did a few test just now but it looks like it did cure my problem.
