USB device installation

USB device installation

[Walter Logeman]

Hi,

I have 2 usb ports.  The Intelleye mouse is working well off one 
port.  I am trying to get a Smartmedia card reader to work off the 
other port.

I have made some steps in what I think is the right direction 
/etc/modules has:

scsi_hostadapter
usb-storage

I have a program called usbview which shows me that the reader can 
be hotplugged, which means usbutils and hotplug are working (I 
think)

I have made a /mnt/smedia directory 

I know I will need to add something to my fstab such as:

 /dev/sda1 /mnt/smedia vfat noauto,user

but have not done that yet... perhaps i should do that now?

I have held off because

 mount -t vfat /dev/sda1 /mnt/smedia

tells me there is no sda1 ( ls -al in dev/ reveals that there is no 
device sd* at all  - see clip below.)

How does the dev directory get the device names?  Should they just 
appear?  Does usb-storage do that?

Any comments or clues would be appreciated.  I am new to Linux so 
may well be missing something very basic.

Some details below

You may have to create the devices. try mknod 660 -m /dev/sda1 c
char-major-NUMBER 1

char-major-NUMBER has to be replaced with the _right_ value
or you may make ./MAKEDEV sda1 in /dev (this may be only possible in other
u*ix distributions.)

SORRY, but it should be mknod 660 -n /dev...

I have searched around and found this page:  
http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/dnamesdevfs.html

But i am still not sure what to enter  for char-major-NUMBER 1

Also you corrected the command to  mknod 660 -n /dev/sda1  but it 
seems n does not work here m= mode?  n 

# mknod 660 -n /dev/sda1 c [b,8,0]
mknod: invalid option -- n

So I am still puzzling here...

no it does not seem to be there...

I'm still hanging out there... maybe I'll spot it.

Probably is the -m flag right. try man 8 mknod. After reading
this I would recommend using

mknod 660 -m /dev/sda1 -b 8 0

But be cautions. I won't - as ever - not guarantee that
this will work. Check it out and if it won't work delete 
the device node. .

rm -i /dev/sda1.

Great to get your help here... I cld not find man 8 for mkmod on my 
PC or the net only man 2.

I kept getting invalid mode with your line... tried some other 
options with no luck.

However mknod created the device in dev when I did not specify a 
mode... that is probably what is wrong now?  (just tried chmod to 
implement the 660 - I think that worked, but the final result is 
the same.)

At least the sda1 is *there* but ... 

see results below...

Where to from here i wonder?

Re: USB device installation

[Tom Beer]

Walter,

please tell us your system (uname -a).
Have you compiled some module for the smart
card reader? If yes, please let me the gcc version
(if you used gcc) know. 
What is your /etc/fstab entry?
Something similiar to

/dev/sda1 swap swap defaults 0 0  

??

What is the exact name of your smartcard drive?

No I have not compiled anything but have modules loaded that I 
thought were needed - ie usb-storage, scsi_mod, usbcore, I will 
append the output of lsmod.

1007 root@psybernet:/etc (11:39:48)

<snip>
/dev/sda1 /mnt/smedia vfat noauto,user

I have just added the last line but I doubt it will work as 

1008 root@psybernet:/etc (11:39:53)
# mount /dev/sda1 /mnt/smedia
mount: /dev/sda1: unknown device

is still the situation.

You should try to track down which modules are needed for the
smartcard drive. A quick web search leaded to no results (for me).
The usb modules you installed are for a mouse and a keyboard, as
far as I'm concerned.

Hmmm... I cant find a thing, not even to upgrade it for XP.  
However i wonder if i need it?

It thought the modules i had, especially usb-storage, did it. I have been
trawling around for instructions and it seems many people get things going with
just this module. But hey, I am a newbie and have no idea.

But I have the idea that usb-storage should have created the device 
in dev/  and it did not.  

Or should i link the sda1 (which i have now made to ... something 
like with my dvd drive:

dvd -> /dev/scd0  

it in turn is linked thus:

scd0 -> scsi/host0/bus0/target0/lun0/cd

Which makes me recall that the sm card is a pseudo scsi card...

There is also a file n that directory called generic

Could that be it?  Something it needs to be linked to.  ??

However i wonder if i need it?

These are regular newbie probs (don't bother, I have similiar ones :-)
That many people get things done with this module means - nothing.
Try to find out which module you need, and then use this particular one.
Picking one module a la carte _won't_ work. This won't work on any
platform. Try to use a device driver designed for product x running
product y under M$ or Apple.
