Negotiation process

Appendix A USB On-the-Go

6. To return control back to OTG-A (host) , OTG-B (device) stops

using bus and becomes peripheral/device.

7. OTG-A (host) sees lack of activity, disconnects and becomes

host.

Host Negotiation Protocol continued:

Note:

If the OTG-B (device) does not STALL the

SetFeature(b_hnp_enable) command, the OTG-A (host) must give the

OTG-B (device) an opportunity to become host before the OTG-A

(host) may turn off
