Hi all!

I am still trying to get /dev/sdXXX using /sys interface but because I got 
only one usb disk , I am not sure of some things .

I got a printer and I plug it in I got /sys/bus/usb/devices/usb1/1-1 directory 
created. Then I plug in my usb flash disk I got 
/sys/bus/usb/devices/usb1/1-2.

Now my questions

1-  ls -al /sys/block/sda/device lrwxrwxrwx    1 root     root           49 
2003-05-12 10:03 device -> ../../devices/pci0/00:07.2/usb1/1-2/1-2:0/1:0:0:0/

Now if I had two or more devices what would device link would show ? ( In my 
example it shows somewhere under /sys/bus/usb/devices/usb1/1-2 directory ).

2- Does the number 1-1 , 1-2 gives any hint about /dev/sdXXX ?

3- Does usb2 devices get their info under  /sys/bus/usb/devices/usb2 ?


With Best Regards,
/ismail donmez
