here you can see I only have one default number 70 rule.
|

So we need to create a rule number greater than 70 to override that rule not giving us the permission we want.

copy the file:

sudo cp <exsistingrule##.rules> <## + 1>-libusb-permission.rules

here's what I did, you rule number and name may differ:

BOOTLOADER:
|
||||
bootloadHID-master:
|
||||
https://github.com/ajd4096/bootloadHID
|
||||
fork of original obdev bootloader has option to remove BL switch with timeout.
|
||||
|
||||
bootloadHID.2012-12-08:
|
||||
https://www.obdev.at/products/vusb/bootloadhid.html
|
||||
the original believe it has more upto date V-USB drivers.
|
||||
|
||||
Both have identical commandline folders so they're identical on the host side.
|
||||
need to have libusb-dev installed can check by typing "libusb-config" in terminal
|
||||
will present usage options if installed on your system
|
||||
if not installed should report so with suggestion for apt-get:
|
||||
paul@eeepc:~/Dropbox/retro_pgmr/INL-retro-progdump/bootloader/commandline$ libusb-config
|
||||
The program 'libusb-config' is currently not installed. You can install it by typing:
|
||||
sudo apt-get install libusb-dev
|
||||
then just run 'make' will hopefully build sucessfully
