[Discuss-gnuradio] cant create two rx

[John Wu]

Hi all, I need to use two rx in my project, however I can not create two rx. My code create rx is bellow:

Rx1 = usrp_standard_rx_sptr(usrp_standard_rx::make(0,decimRate,1,-1,
                                                         usrp_standard_rx::FPGA_MODE_NORMAL,
                                                         1024,16*8,rbf));

Rx2 = usrp_standard_rx_sptr(usrp_standard_rx::make(0,decimRate,1,-1,
                                                         
usrp_standard_rx::FPGA_MODE_NORMAL,
                                                         
1024,16*8,rbf));

the error:
usrp_open_interface:usb_claim_interface: failed interface 2
could not claim interface 2: Device or resource busy
usrp_basic_rx: can't open rx interface
