Frequent hardware buffer overflow message in sniffer

[WillemOuwerkerk]

Hi Alex,

When sending large chunks of data over my CDC interface i frequently
get the message below. The data arrived correctly but the sniffer does
not show parts of it. Can you tell me if this can be solved?

Kind regards,
Willem Ouwerkerk

This is not a sniffer issue. This message means that sniffer could not send all the data to the host interface. This may happen under a heavy load. It is strange to see it in a sequence if IN/NAK packets. It is also possible that your capture PC is slow and can't read the buffer in time.

You need to do a speed test and make sure that your sniffer is connected as close to the root hub as possible.

Thanks Alex starting a new discovery

Removed de external HUB for measurements and now it's ok, thanks Alex.
