But then, I've got an external Firewire drive, and it's recognized
at boot, as are all my thumb drives, so maybe your product doesn't
follow some spec well enough, and new kernels are more strict than
older kernels.
would there be any way how to find you if this is the case?
????
i meant, seeing/checking somehow in more detail,
/var/log/syslog
/var/log/boot
/var/log/dmesg
But you probably knew that...
if the kernel really
has this sort of problems. what puzzles me is, that if i re-plug the
drive later to the same port, it works without problems.
It's probably that the D/port is poorly designed, taking too long to
initialize, or some such.
i've seen on the web a suggestion to use
echo Y > /sys/module/usbcore/parameters/old_scheme_first
but i don't know how to set this (if it is gonna help) at the very
beginning of the boot process (some 4 seconds after the grub gives the
control to the kernel according to the timer). is there any kernel boot
option to do this?
/etc/sysctl.conf
