Re: [microblaze-uclinux] USB & Hotplug

Hi everybody,

I've been working with the USB with no results:

Making cat /proc/devices I get this:

Character devices:
  1 mem
  2 pty/m%d
  3 pty/s%d
  4 ttyS
  5 console
 10 misc
 90 mtd
162 raw
180 usb
254 de3

Block devices:
  1 ramdisk
 31 mtdblock
254 System ACE

So I changed make file adding this line:

DEVICES =+ sda,c,180,0    sda1,c,180,1

Then: mount -t vfat /dev/sda1 /var/pendrive
mount: Mounting /dev/sda1 on /var failed: Block device required

If I make: mount -t usbdevfs /proc/bus/usb:

# ls /proc/bus/usb
001      002      devices  drivers
# cat drivers
         usbdevfs
         hub
         usb-storage

I think I'm very near from my target...but I don't find a solution :-(

Do you have any idea? What could I do now?

Thank you very much for your help!

Kind regards,

FYI, I posted a 2.6 driver for the cy7600 yesterday:

http://thread.gmane.org/gmane.linux.usb.devel/53285

It contains a HCD driver and the start of a gadget driver.
