How to check USB CRC error?

Hi Expert,

In our TX2 application, we found the USB contoller was crashed sometimes. We suspected it’s related to signal quality. I think there should be CRC error statistics if physical link is bad like other serial link. Which registers can we dump to check the USB CRC error counter?


Have checked with our teams and confirmed there is no register defined by USB/XHCI specs to reflect CRC error. We use USB bus analyzer to check CRC error from bus.

Thanks for reply. But it’s not reasonable, USB3 is very high speed and usually connected with a cable. USB bus analyzer can’t reflect real connection. CRC is directly showing the result at receiver side.
