USB hard drive not showing up

After recompiling the kernel with SCSI disk, USB mass storage support etc you can see something like this in the kernel log:

usb_control/bulk_msg: timeout
usb.c: error getting string descriptor 0 (error=-110)
usb.c: error getting string descriptor 0 (error=-84)
usb.c: error getting string descriptor 0 (error=-84)
scsi1 : SCSI emulation for USB Mass Storage devices
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 2

How ever /dev/sda did not work. The solution was:

echo "scsi add-single-device 1 0 0 0" > /proc/scsi/scsi
