I have the same problem, the buffer constantly drops after 10 seconds and it doesn't matter what the width is

This is a bug with many causes. On the RPi5 I would suggest trying to power the bladeRF separately via the DC barrel connector.
@ccgauche If you are in VM, please ensure xHCI accleration/passthrough is enabled.
@Andrii067 With regards to buffers dropping, it is imperative that the thread calling bladerf_sync_rx() receives samples then saves them and immediately comes back to calling bladerf_sync_rx(). DSP should be left for another thread.

@rghilduta I also tried with the blade powered from the barrel jack and the error still happens... I'm running flat raspbian on my RPi5...

On the jack barrel. My DC barrel is rated for 5V - 2A. I can try to find another one if it's not enough but from the bladeRF docs I've seen it should be enough. Also I'm only using the bladeRF RX so I should need less power ?

Edit:
The issue doesn't arises on x86 computers nor the khadas VIM3 ARM board running the same exact software stack as the RPi5. Thus either pointing toward an issue with the USB Controller on the RPi or the Power delivery on the RPi USB ports. Through the issue also happens while plugged with the DC Barrel (maybe an issue with my power cord?)
