I have no way to reproduce this; my Mac is not supported by MacOS newer than 10.5, and doesn't have USB3 anyway. :smile:

Changing num_transfers to 1 fixes this issue :) https://github.com/zeldin/libsigrok/blob/b7ab9ed40f85f1e1ef55c938d73fef0ef6ff72eb/src/hardware/fx2lafw/protocol.c#L670

[zeldin]

That leaves you with 0 host side buffering during descriptor change though, so hardly a good solution. I wonder if there is some kind of bug in libusb causing this? I take it that num_transfers == 2 (which would be way better than 1) won't work either?

[cozycactus]

works only with num_transfers == 1 :( and then long transfers are regularly timed out...

I'm encountering this on Ventura 13.2.1 (22D68)
