[AM1806] add garbage data in USB controller

Dear Champs,

Is there any possibility to add garbage data(0xFB) in USB controller?

In my customer's test, they found Invalid data(0xFB) was added after response NAK for IN Packets several times, and thus HOST was worked it as 'Invalid Packet'.

So, they are checking if this garbage data caused by USB controller or SW and requested to check if there is any history like this.

Thanks and Best Regards,

SI.

    Hi Sung-IL,

    I have not come across such problem. Most likely there is no history of this sort.

    This is most probably a software / driver issue. What is the name of the software package you use? Is it the TI released one or your own driver? Is it a starterware package?
