Bug#595525: libhamlib2: hamlib requires sudo for USB kit radios

[Kamal Mostafa <kamal@whence.com>]

Package: libhamlib2
Version: 1.2.11-1
Severity: normal
Tags: patch


Hamlib-based apps require the use of sudo for the USB kit radios
(elektor507, si570avrusb, dwt) which have an embedded "generic"
USB serial converter (FTDI, AVR USBasp):

  $ rigctl -m 2507
  rig_open: error = IO error 
  $ sudo rigctl -m 2507
  Rig command: 

Specifically, hamlib's attempt to usb_detach_kernel_driver_np()
fails because of root-ownership of the USB device node (e.g.
/dev/bus/usb/005/004).

Attached udev rules file enables ACL for the node when the device
is attached so that sudo is no longer required.

#
# Enable ACL_MANAGE for common embedded USB-serial converters so that
# applications which call usb_detach_kernel_driver_np() won't need sudo.
