USB 8451 I2C error 301740 during a write

I have this USB-8451 I2C device and I do not see any clock activity on the scope on the SCL line (always high). The SDA line is always low when I power-up the device which is an indication of a Start Condition if SCL is high. I have 2K pull-ups on both; the SCL and SDA lines. Without connecting any slave device to it, I do not see any activity on the SCL when I do a write. With the slave device attached, I still get the same error message and on the scope I do not see any activity on the SCL line.

 

Any ideas?  The basic vi I wrote is attached.

 

Thanks,

Noberto,

 

I have spoken with Austin, the AE who you were speaking to on Service Request 1728007, and he has indicated that you have sent this device in for an RMA.  Is this correct?

 

Is there any other way I can help you in this?

Yes, the device should go out today for repair. For some reason the SDA line is stuck low.

Yes! It is possible to borrow same device from a near office, so that I can continue with the development of our application?

 

Thanks,

Norberto,

 

I don't have access to that information, but if you call back in on your Service Request number, you can be routed to someone who can help you with that request.
