Re: sending data to usb port

[Jack Craig <jack.craig.aptos@xxxxxxxxx>]

how about

you plug in your USB widget & identify the device node (/dev/sdc1, for example).

say your src data is in /tmp/junk

# dd if=/tmp/junk of=/devsdc1    [any other args you might want to shape the write and some error handing ( i think, it was a long time ago...)]

man dd    {for more options}

hth,....

Hi!

Imagine I have some device connected to USB port. Is it possible to send some code directly to that port?

Here's what I'm trying:
# echo "0" > /dev/bus/usb/004/010
-bash: echo: write error: Invalid argument
