Trying to use YS1 rootless with rfcat

[dazer]

I've been trying to use my YS1 rootless, but I'm having difficulties.

I've created my entry in /etc/udev/rules.d as described here: https://github.com/ecc1/rfcat/blob/master/etc/udev/rules.d/20-rfcat.rules

name@host:~ $ cat /etc/udev/rules.d/20-rfcat.rules
SUBSYSTEMS=="usb" ATTRS{idVendor}=="1d50" ATTRS{idProduct}=="605b" MODE:="0660" SYMLINK+="RFCAT%n", GROUP="dialout"

This matches my YS1   

name@host:~ $ lsusb
Bus 001 Device 004: ID 1d50:605b OpenMoko, Inc.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

But after running

sudo udevadm control --r

(and even after a reboot) I get this:
 

name@host:~ $ rfcat -r
Error in resetup():Exception('No Dongle Found.  Please insert a RFCAT dongle.',)
Error in resetup():Exception('No Dongle Found.  Please insert a RFCAT dongle.',)
Error in resetup():Exception('No Dongle Found.  Please insert a RFCAT dongle.',)
^CTraceback (most recent call last):
  File "/usr/local/bin/rfcat", line 56, in <module>
    interactive(ifo.index, DongleClass=RfCat, intro=intro)
  File "/usr/local/lib/python2.7/dist-packages/rflib/__init__.py", line 190, in interactive
    d = DongleClass(idx=idx)
  File "/usr/local/lib/python2.7/dist-packages/rflib/chipcon_nic.py", line 295, in __init__
    USBDongle.__init__(self, idx, debug, copyDongle, RfMode)
  File "/usr/local/lib/python2.7/dist-packages/rflib/chipcon_usb.py", line 176, in __init__
    self.resetup(copyDongle=copyDongle)
  File "/usr/local/lib/python2.7/dist-packages/rflib/chipcon_usb.py", line 302, in resetup
    time.sleep(1)
KeyboardInterrupt

but immediately after that, it still works with the sudo

name@host:~ $ sudo rfcat -r
No module named enum
'RfCat, the greatest thing since Frequency Hopping!'

Research Mode: enjoy the raw power of rflib

currently your environment has an object called "d" for dongle.  this is how
you interact with the rfcat dongle:
    >>> d.ping()
    >>> d.setFreq(433000000)
    >>> d.setMdmModulation(MOD_ASK_OOK)
    >>> d.makePktFLEN(250)
    >>> d.RFxmit("HALLO")
    >>> d.RFrecv()
    >>> print d.reprRadioConfig()

Any ideas what I'm doing wrong?

Many thanks!

On a whim, I started with a clean install of Raspian, did the same sequence  to install and it's working like a dream.
