USB stick problem after compiling

Hi guys,

I compiled the latest kernel with success.

I made it with make oldconfig and the only thing I changed manually was support for 4GB ram.

Now, I can see 2GB ram, but when I insert my usbstick I cannot mount it.

result of dmesg | tail says..

sdb: Mode Sense: 3e 00 00 00
sdb: assuming drive cache: write through
SCSI device sdb: 504320 2048-byte hdwr sectors (1033 MB)
sdb: Write Protect is off
sdb: Mode Sense: 3e 00 00 00
sdb: assuming drive cache: write through
 sdb: sdb1
sd 5:0:0:0: Attached scsi removable disk sdb
sd 5:0:0:0: Attached scsi generic sg1 type 0
usb-storage: device scan complete
but /dev/sdb1 does not exist !!

what should I do to be able to use it ?

I wonder... do you use UDEV perhaps? If so, did you also upgrade to a udev package that can be used with this bleeding edge kernel? For instance slackware-current which has this kernel in the /testing tree comes with udev-071 which is the minimum required version of UDEV that can work with the latest kernels.
If you do not use UDEV (i.e. the file /etc/rc.d/rc.udev is not executable) then make sure that the device files /dev/sdb and /dev/sdb1 are created if missing.

I had the same trouble when I updated to the 2.6.16-5 kernel. Check /etc/fstab and make sure there is a mount point for your usb drive. Then you can manually mount it as I was able to.

Hope this helps

the problem was /etc/rc.d/rc.udev was not executable. It was the correct version 071 but not executable.

I dont know how this was changed during kernel compilation, but now I changed it to executable and it is working.

thanks for the tip bob.
