Issue with USB2ANY r/w

Other Parts Discussed in Thread: USB2ANY

Hello Sir/Mam

We are using USB2ANY Adaptor to r/w on our I2c Switch but we are getting Write timeout and sometimes we are getting 00 when we read back the value we have written.

Can you please tell what might be the issue as it is working with 1-2 systems.

    Hi Prabhjot,

    The only time this should be happening is if the USB2ANY successfully addresses a slave device but fails to write all of its data within 20ms. This suggests that someone on the bus is holding the SCL line low for too long. Are you trying to use the USB2ANY in a multi-master bus? USB2ANY does not support this use case as far as I can tell.

    Regards,
