Title: SETUP packet response missing
Post by: Nik on October 22, 2014, 06:39:05 pm

Hi,

As a USB MSD Host, I am trying to communicated to a MSD, but it is failing in the initial SETUP stage. The device simply does not respond (neither ACK nor NAK) to the requests.

Any clue ?

Thank you for your time.

Got it.

The device either responds with ACK or does not respond at all.

Need to check what else is missing.

Issue closed !

The hardware analyzer was pulling the data lines up(not expected from an analyzer !) causing the SE1 condition.

Thanks!
