usbpush

hi everybody i have ubuntu desktop and i m using minicom for communicating
with mini6410, i fuse uboot on sdcard and i want to write linux image on
board but usbpush dont work and get error cant download file, Has this
board another tool like dnw for mini6410, tnx a lot.

another information:
 this tool must work in Linux os surely,
 can i use dd or minicom transfer protocol?
 i use this command ./usbpush zImage_n45 0xc0000000

changing following line from 0x03 to 0x02 solve my problem

#define QT2410_OUT_EP    0x02
