Multiple BladeRF boards RX

[mlm_pd]

Hello, I'm trying to receive data from two distinct BladeRF boards connected to the same PC using a python application.
When I launch my application on the first interface everything works fine, but as soon as the second instance on the other interface starts receiving (sync_rx), I receive the following error:

Code: Select all

[ERROR @ host/libraries/libbladeRF/src/backend/usb/libusb.c:1230] Failed to submit transfer in submit_transfer: LIBUSB_ERROR_NO_MEM

Is there some particular configuration I have to set in order to use multiple devices simultaneously?
Thanks in advance.
