THat should work fine. If you have nothing in /proc/bus/usb/devices
something is very wrong. What do you log files show when you load the
drivers? lspci -vvv will be informative too.
Unfortunately I don't have picutils installed.
Here comes my /proc/bus/usb/devices:
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=1 Spd=12 MxCh=2
B: Alloc=0/900us (0%) #Int=0 #Iso=0
D: Ver=1.00 Cls=09 (hub) Sub=00 prot=00 MxPS=8 #Cfgs=1
P: Vendor=0000 ProdID=0000 Rev=0.00
S: Product=USB UHCI-alt Root Hub
S: SerialNumber=7000
C:* #ifs=1 Cfg#=1 Atr=40 MxPwr=0mA
I: If#=0 Alt=0 #EPs=1 Cls=09 (hub) Sub=00 Prot=00 Driver=hub
E: Ad=81(I) Atr=03(Int.) AmPS=8 Ivl=255ms
And nothing changes there when I plug the mass storage device...

Something is serious wrong with your system then. Do you have something
like "USB Legacy" turned o nin your BIOS? If so, turn that off.
I own an ancient MaxData Artist laptop. Its BIOS has very little options
to change & none of them are about the USB (I've read that Plug'n'Play
OS option may cause USB bugs under Linux on some laptops, so I checked
it was turned off). I asked the question if it is ok when I use USB 2.0
drive with USB 1.1 hub on another maillist & I was answered it is. It
must be some buggy hub hardware (it reports it is PIIX4). That's why I'm
looking for USB driver developers here to help me make a fix.

What drivers do you have loaded? What is in /proc/bus/usb/devices? What

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?

Sounds like you must have a hardware or pci problem. 'lspci -vvv' shows?
USB virtual root hub seems to be ok (PCI:00:07:2). It works ok with a
USB mouse also.

And there are no error messages in your log files?
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.
