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.crtp.radiodriver:v99.55 dongle with serial 2F40C62A17 found
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.

For seeing the Crazyflie when connected on USB, it will appear as an STMicroelectronic devboard when connected to USB (we now have our own VID but we have not used it yet ...). To check actual device name you can run this command:

sudo lsusb -v | grep iProduct

If you cannot see it, check your USB cable. I have experienced many USB cable that did not have data lines but only the power line.

Finally you could check that your udev rules are well setup for the Crazyflie.

thank you for the answer. using a new cable helped as it can now be seen on my terminal when using the command you provided. I still cannot connect to it through the radio except when I try to bootload but at least I have something to work with thank you.
