USB booting :: mounting sd-usb pendrive



Hello, i have a zaapa usb key, no memory embedded, with a mmc card 1gb installed. it is mounted under windows, ubuntu and guadalinex v3.
I boot dsl 301 from cd but the usb key doesnt appear anywere. i have tried to locate it in /dev/sda and /dev/dev/sdax (some numbers) and not found
When i try to install DSL, the application Usb-hdd and usb-zip locate it at sda, but when the script starts says "no valid device"

Mounter at low right of the screen doesnt mount it

”””””HEEEEELP PLEASEE!  I love DSL, and would like have it in my pendrive.

Thank you!
