[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.
