Maple Mini board not connected?

[dbhaig]

Hello.
I am running Ubuntu Linux

I have loaded the hid_maple_mini.bin onto my maple mini clone board, following the procedure describe here: https://www.youtube.com/watch?v=Myon8H111PQ

When I plug in the board,

lsusb returns: ID 1209:beba InterBiometrics

ls /dev/ttyUSB* returns nothing

When I try to upload a sketch using the Arduino IDE I get the following messages:

error, counldn't open [/dev/ttyUSB0]

Which version of STM32 core did you install?
I had a negative experience with 1.9 and 2.2.2. maybe you give 1.8 a try.

I am using 1.9.0. I will give 1.8.0 a try.

Thanks
