Hi
we are working on USB Host Driver (2.0) on omapl138evm. We are using LINKSYS Cable Modem (Full Speed) as device with high speed hub. We have implemented NAK Time Out Feature (HOST_RXINTERVAL register) for Bulk IN transactions only and it is working fine. But unfortunately, Cable Modem does not enumerate if hub is introduced in hardware setup.
Does this feature (NAK TIME OUT) works with high speed hub along with full speed device?
From the USB log, it is observed that When Bulk IN Start Split is started, slave ACK the transaction. Due to this ACK, when Bulk IN Complete Split is started, slave responses with NAK. Due to this, ACK / NAK, Time Out Feature is not working.

Qasim
