I have a creative muvo 128mb flash drive/mp3 player that I'm trying to use with an Inspiron 8600 with FC2, kernel 2.6.9. When I plug it in, lsusb gives

dmesg shows
Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage

but cat /proc/scsi/scsi shows no attached devices. How do I get it to show up in /proc/scsi/scsi?

I have put the following in /etc/modules

uhci_hcd
usb-uhci
ehci_hcd
scsi_mod
usb_storage
vfat
i8k -force

but the modules usb_storage and sometimes scsi_mod won't be loaded unless the muvo is plugged in on boot.

I thought the modules listed in /etc/modules would always be loaded at boot, why isn't this true?


no mount commands work either;

[root@localhost ashlock]# mount -t vfat /dev/sda1 /mnt/muvo
mount: /dev/sda1 is not a valid block device

because the muvo is not even being associated as sda1 since /proc/scsi/scsi is empty

[root@localhost ashlock]# mount -t usbfs /dev/sda1 /mnt/muvo
[root@localhost ashlock]# ls /mnt/muvo/
001 002 003 004 devices

which just mounts and empty usbfs on /mnt/muvo

this is driving me nuts. I have used linux since 1996 but the number of hours I have spent trying to do the simplest things like mount a thumb drive and use a projector via dual head have been making me consider going to the dark side.

Did udev assign it to /dev/uba1

Thanks musicman_ace for restoring my faith in the force, you're a genius!

I found that I didn't have the udev package installed, so I did a 'yum install udev' and then 'mount -tvfat /udev/uba1 /mnt/muvo' and it worked! None of the 10,000 posts I googled for usb sticks mentioned anything about udev, only /proc/scsi/scsi, and since I actually got it working using /proc/scsi/scsi for two of the 1000 times of trying, I thought that was the only way to get it working.


Then I added

/udev/uba1 /mnt/muvo vfat user 0 0

to /etc/fstab so I could just type 'mount /mnt/muvo'. beautiful. If you're ever in Boulder, lunch is on me.

Now, is there any way to stop usb power before I unmount and unplug it? In windows, stopping it causes the red power light on the muvo to turn off before unplugging it.


thanks

add lines to fstab only works if udev consistantly assign the same device node to it. I've never seen a /dev/uba1 before, so at some point it may assign it /dev/sda1. If it doesn't work, just try dmesg as that is where I got it from.

How about

Hmm, maybe disabling ub would let the scsi approach work as discussed in that post.
However, I would have to recompile my kernel just to check it out. I will stick with the udev approach as it is working consistently for now.

Today, I just ran into related issue.

5.2.4 in following

may help in case things go wrong.
