Most common and simple udev rule...that doesn't work...

Hello,

I'm not a newbie but I've obviously a very simple problem that is so simple and give to me this illogical issue I can not respond for myself

I have a usb dongle, when I connect it udevadm monitor give :
ID_VENDOR_ID=0bda

I have a udev rule in /etc/udev/rules.d, far simple :
SUBSYSTEM=="usb", ATTR{idVendor}=="0bda", RUN+="/usr/bin/echo 0101010 > /tmp/try"

And It don't work, since 2 hours I try it adding ATTR, ACTION...

Thanks for help

Hello

the > is a shell construct, RUN does not run commands in shell, change to run such command in a shell RUN+="/bin/sh -c 'echo > blah'"

Good luck,
