BTW, hotplug should do that all for you if you just 'modprobe usb-uhci'
(or the correct host driver, lspci which show which one).
I've audited hotplug scripts already. They all are based on /proc/bus/usb/*

What drivers do you have loaded? What is in /proc/bus/usb/devices? What
does 'lspci -vvv' show for that device?
modprobe usb
modprobe [uhci,usb-uhci,usb-ohci]
modprobe usb-storage
/proc/bus/usb/devices doesn't contain anything but 1-line comment.
I can provide the lspci output only tommorrow.
What happens in your log files and /proc/bus/usb/devices when you plug in
your storage device?

USB virtual root hub seems to be ok (PCI:00:07:2). It works ok with a
USB mouse also.

No. All the drivers are loaded correctly. The only thing which is
disturbing me is that USB driver doesn't report any unclaimed devices at
any stage (& only unclaimed devices are scanned as new drivers e.g.
usb-storage are loaded).
So, I need some kind of USB scanner (USB I/O range scan before & after
plugging showed up no difference as I mentioned earlier) to figure out
what is going on.

Well, all the explanations start with the fact I see my device in
/proc/bus/usb/* but I don't

I got a noname usb drive recently marked as "Samsung 128MB". It works ok
plugged into my FreeBSD desktop as Lexar Jumpshot but it fails on my old
Linux laptop. The problem is that USB driver doesn't report any
unclaimed devices, so nothing happpens when I do `modprobe usb-storage`.
I think my question is addressed to developers mostly: how can I figure
out if the USB driver is able to work with the device (btw, I have a
PIIX4 USB hub)? I tried to scan the USB I/O range (0x7000-0x701f) but
nothing changed when i plugged the device. Now I'm working on figuring
out the call-stack in my case (any help from developers again?) &
inserting more log messages.
