crazyfile connection question (after scanning nothing shows up for select an interface for cfclient)

[mattnoh]

Hello I am currently trying to learn about crazyfile and encountered a problem when I try to connect to it.

When I try to connect my crazyflie to my ubuntu using cfclient after I press scan the crazyradio cannot find my crazyfile and the select an interface which I think is supposed to show the address of the drone remains blank. This is the terminal when I scan for the crazyfile

INFO:cflib.crtp.radiodriver:v99.55 dongle with serial 2F40C62A17 found
INFO:cflib.drivers.cfusb:Looking for devices....
INFO:cflib.crtp.prrtdriver:Initialized PRRT driver.

INFO:cflib.drivers.cfusb:Looking for devices....
INFO:cflib.crtp.prrtdriver:Initialized PRRT driver.

which I do think means that at least the radio is working

I have tried to put to drone into cold boot recovery mode and managed to initiate bootloader cold boot and program the firmware normally I think. however after that it still cant be seen by my pc.
I think there might be a chance that the address of the drone might have changed since this is not a new crazyfile but I tried to reset the EEPROM following the guide in the bitcraze site. however when I plug the crazyfile to my pc I dont think it recognizes as with using lsusb nothing shows up.
However while trying with a new crazyfile out of the box cfclient still cant recognize any signal

I do think that I must be missing something very simple and I would appreciate some advice.
thank you.
