 |
|
Hello,
Recently I acquired an iAudio M3 mp3 player. Like others, it's basically a 20 GB hard drive with a usb interface and some firmware to play mp3, ogg, etc. I'm trying to get it to mount as a filesystem in Gentoo.
In the kernel, I added all the bits for USB driver types and I put in VFAT as a recognized filesystem type. However, when the M3 connects via USB, I get the following in /var/log/messages:

I'm not sure how to make sense of this. I have made it connect using the Knoppix LiveCD, but the device file in fstab was strangely complex and the /dev structure didn't match the gentoo.
I think I'm using devfs as I just redid the kernel and root and I haven't reswitched to udev. It seems to be located in /dev/ub/a rather than /dev/usb/sda1 (or similar).
Any ideas?
Regards,

I hadn't heard anything, so thought I'd bump it once just to see if any fresh eyes see it and know what's going on. Thanks.

If I remember correctly, if your kernel has this option selected:
-> Device Drivers -> Block devices -> Low Performance USB Block driver
it will cause the device to connect under /dev/ub/x and will cripple the usb-storage driver. Once you disable that kernel option, it should connect under /dev/sda1, which fixed most of the problems I was having with my iAudio.
My fstab line is pretty basic:
/dev/sda1 /mnt/iaudio vfat defaults,noauto,rw,user 0 0
I just have to use the same usb port, which isn't much of a hassle. Hope this helps

Yeah it does. I'll try adding that to the fstab line.
and you brought up something I just realized (aggravatingly) today. it DOES matter which port you plug into. I've been toting it back and forth from work with work on it, and I tried to use the front USB ports on my box. No go...
Any idea why this happens?... it wasn't even that it put it at a different address. It wouldn't assign a device to it AT ALL.
