Update
First, I have to thank you for all your help you're giving to my project; i really appriciate it.
I managed to compile the file that was missing. Now yate runs well but I still get the same LIBUSB_TRANSFER_ERROR yet again.
Now. I tried the card on a linux notebook and it works all well.
Leds are flashing and I can see my network on the phone. I have now an issue: I cannot register my phone. I setted regexp=^* but my phone fails to register.
Before trying to solve the last problem I need to know the answer to this question that is, for me, the most important over all.
According to these informations, could it be an ARM (raspberry) related issue?
I.e. : will I ever be able to run yatebts on raspberry or not?
In addition, I have to solve this issue also, though.
Thanks in advance.
