[Clfs-support] booting from usb stick

[mike]

hi

i've some trouble to boot from usb stick.
i use my current kernel and a minimal clfs file system. bootloader is 
grub. the kernel is booting but hangs on the point to mount the rootfs 
read only. grub boots with: kernel /boot/usbkernel-2.6.23   
root=/dev/sdb1 vga=791
on my laptop the hdd is also a 'scsi' disk and there it boots fine. i 
think the kernel is not ready with usb device scanning while mounting 
the rootfs ro has started. has any one a idea?
