And I think you expect too much from such information. If you have CRC errors, it's not relevant what counter increases. Simply the fact that something bad happened during transport is the most important information here.
Then you need to find the root cause which is usually in these areas: cable too bad, too long, too bad connectors, bad solder joints, bad shielding, etc.

Just assume that such counters would be documented if it were helpful and made troubleshooting more efficient.

I would simply be glad that RME visualizes these error counters in the driver settings to have a clue that you have a concrete problem in the cabling and not only problems around DPC latencies or system load.

This is an invaluable advantage in contrast to other manufacturers who do not display such things.
You can at least rule out cable issues rapidly if you have clicks and pops.
That's what it's there for.

Out of interest, are these CRC errors something that is a standard to USB? I'd be interested to read a bit more into it. Is there somewhere that I can look into that sort of thing?

Thanks all for the input! I'm looking at jumping over to a new laptop for my remote recording rig and I'm trying to stress test the I/O ports on the laptop; I'm currently in the world of USB3.1 Gen 2 and Thunderbolt 4 and, bleurgh... Why can't they just stick an old USB2 on it for me

0 crc5/16 err / 9.3 min

Minutes should be clear … cross-check with your watch.
It's the amount of time the CRC check is running (how long you have the driver settings window open).

If there are CRC errors, the counters will increment.

I'm still not exactly clear about what each bit of the data is saying/showing.
Is the top line showing the number of USB errors in the ' -|0|- ' part? Is that the error count? Showing that I have 0 errors?

Or, is the ' 0 crc5/ 16 err ' part the number of errors, in which case is it showing me that I have 5? or 16? errors?

and the last bit, the time. Is that just showing the amount of time the tracker has been running? My initial thought is that this was showing an average number of errors per minute. e.g. if it showed ' 2.5 min ' that might mean I was averaging 2.5 errors every minute.

I'd really appreciate a bit more detail to understand exactly what I'm looking at here.

Also, is there a section that keeps a log of sync between the MADIface and the optical source it is being clocked from? e.g. if there is a syncing error, does it keep a record of it? Or does it just flash on the MADIface for the duration of the loss of sync?

Many thanks, David

could anybody shed any light on exactly what these series of numbers means.

In the 'MADIface Series Settings' panel that I open from the bottom righthand corner of my windows laptop there are some numbers I'm curious to understand exactly what they mean.

There is 'USB Diagnosis -|0|-' on the top line. What does this reference? What does the value '0' mean here?

Under that there is a line which at the moment reads '0 crc5/16 err / 9.3 min'. However, the 'X.X min' part is counting up, I presume it is counting a period of time?

Anway, it would be great to know exactly what these numbers mean so that I can understand if I'm having any issues here. I think I read in the manual that crc5 is 'normal' but I've no idea what it's referencing.

Thanks for any help, Dave
