When using BladeRF 2.0 A9 I noticed this issue:

[ERROR @ host/libraries/libbladeRF/src/board/bladerf2/bladerf2.c:123] _bladerf2_initialize: dev->backend->get_fpga_version(dev, &board_data->fpga_version) failed: Operation timed out
[ERROR @ host/libraries/libbladeRF/src/board/bladerf2/bladerf2.c:2186] bladerf2_load_fpga: _bladerf2_initialize(dev) failed: Operation timed out

Here are the stats for USB device:
ugen4.2: <Nuand bladeRF 2.0> at usbus4, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=ON (200mA)
{
    UE_CONTROL_OK       : 518
    UE_ISOCHRONOUS_OK   : 0
    UE_BULK_OK          : 2574
    UE_INTERRUPT_OK     : 0
    UE_CONTROL_FAIL     : 0
    UE_ISOCHRONOUS_FAIL : 0
    UE_BULK_FAIL        : 26
    UE_INTERRUPT_FAIL   : 0
}


Not sure what happens, this may be a problem at USB 3.0 stack. However, looks like at some point bulk transfers are failing.

Please let me know if you need more debug data.

Hi,

usbdump -i usbusX -f Y -s65536 -vvv

might sched more light into this.

Can be started before you plug the device. X.Y are numbers after ugen.

--HPS
