Re: [microblaze-uclinux] USB & Hotplug

["Raúl Rodríguez Canales" <raul.rcanales@xxxxxxxxx>]

Hi all once again!

I want to add some new information:

cat /proc/scsi/scsi
Attached devices: none

I know there should be usb-mass o something like this, isn't true? How can I add this?

In DEVICES += ... I changed the 'c' for the 'b' and this is the result:

mount -t vfat /dev/sda1 /var
mount: Mounting /dev/sda1 on /var failed: No such device or address

and finally:
cat /proc/ioports
a5000000-a5000fff : CY7C67200/300 Embedded USB controller

a5000000-a5000fff : this direction is given by the MB manual.

Best regards!

Dear all,

Option I have enabled are:

SCSI support
    SCSI disk support
    SCSI generic support
    Probe all LUNs on each SCSI device

Support for USB
   USB verbose debug messages
   Preliminary USB device filesystem
   CY7C67200_300 EZ-USB support
   USB mass storage support
         USB mass storage verbose debug    

I can't find SCSI device support! Do I have to enable another option to find this one?

Sorry if i'm wasting your time

Thank you!

You need to enable the SCSI subsystem, and usb-storage

These should be block devices ('b'), not char ('c')

Enable SCSI device support - it implements the block device interface
for usb-storage.  That will get you a bit closer.

I'm not sure why your USB drive is not appearing in the list of
/proc/bus/usb/devices - but take one thing at a time.

Regards,

John
