Cannot mount usb storage under 2.6.9


Hello everybody,
Till now I have been using my usb mass storage device with success under 2.6.7. All I had to do was to load usb_storage and uhci_cd modules and my usb device was recognised as /dev/sda1.
When I passed to 2.6.9 and tried to mount my device I got something like "sda1 is not a valid block device". Is there something I am missing concerning the new kernel?
Any help is appreciated.

Do you have the scsi drivers built into your kernel?
I had this problem, and I recompiled with the following drivers included:

legacy /proc/scsi/ support (I don't think this one's important)
SCSI disk support
SCSI generic support

You should be using udev with 2.6.X and it sounds like you don't have a proper rule for your drive. Check out this link http://www.reactivated.net/writing_udev_rules.html

You are right "MykilX" Thank you!
I installed udev and hotplug and my usb mass storage device can be mounted again properly. Interesting enough, it is recognised as /dev/uba1. So because I don't like hotplug (it slows the boot proccess a lot) I removed it as well as udev but kept the /dev/uba1 file. Then did a modprobe ub, modprobe uhci_hcd and voila, my usb is working again without udev and hotplug.

In my case, /dev/uba was created with no apparent help from udev. In fact, I'm not certain that hotplug is creating this device, either. I suspect it's because I compiled kernel support for USB in 2.6.9, and I didn't have enough sense to look at all the entries in /dev/ before assuming that 2.6.9 was not supporting my external USB hard drive. It is now, and I suspect it was all along. There's no mention of "ub*" in my udev rules, but I haven't tried disabling hotplug to see if the device is created apart from hotplug.

Low Performance USB block device

I had same problem with 2.6.9! I fix it disabling in kernel configuration ( make menuconfig )

Device Driver--> Block devices --> Low Performance USB block device

Have fun!
