Raspberry Pi installation weirdness

Support
#1

I am trying to implement a Little Backup Box: ( https://chiselapp.com/user/dmpop/repository/little-backup-box/wiki?name=Little+Backup+Box ) which uses Blinkstick.

Following your instructions here: ( https://www.blinkstick.com/help/raspberry-pi-integration ) I was able to get blinks using the command line, until I rebooted to test the backup script. Now (and apparently on further reboots, as I have tried several times) when I issue a command on the command line, ‘even blinkstick --info’, it just pauses for a few seconds and returns to the command prompt with no feedback, no errors and no action.

Help? I am quite at a loss as to where to even start troubleshooting this.

#2

I should add this is on a Raspberry Pi Zero running the latest Jessian

#3

Does BlinkStick work if you plug it in and then unplug it?

#4

No, but using a another boot card, I followed these instructions and command line works

Now to get the script working, and figure out if I can back out the bad instructions or if I just have to junk that install

#5

and it’s back to no responce on the new build. It only seems to work on the reboot after install. Subsiquent reboots do not work. un plugging and plugging back in has no effect. niether does moving to a different USB port

Also, prior to install, the blinkstick would flash once on boot up. Now it does not. Nor doe is flash when first plugged in.

After installing this: http://4dc5.com/2012/06/12/setting-up-vnc-on-raspberry-pi-for-mac-access/

and then installing Blickstick, I get the following results and errors:

EDIT- I see, it is a permission error… sudo blinkstick --add-udev-rule and reboot solved it. On to the next test

Hi scottfrey!
did you modified sth from the source code of Little Backup Box?
