Which option do you take, a direct 1766sto, or b Connection over analog switches? For bus switch of Full-speed USB, these analog switches are available.
For b Over analog switches option, such a sliding door is not required. Isn’t that the obvious way to go for something that needs to be both a Host and a Device?! USB spec provides these receptacle options for each function. To connect two receptacles to this ports, there are two 176s6tk. This is for end device.

Your Host circuit is almost similar to Olimex one. By continuing to use our site, you consent to our cookies. But the emitter and the collector are swapped on the schematic.

Aha surely, It’s PNP. Anyway, try host and device separately, first.
Kindly let me know if what i am trying is right. The USB Device is enumerated fine for above code. I don’t know why it works. When you take b over analog switches, the Olimex circuits around the receptacles are applied as is. I xch to have a option which will be able to detect the connection type.
For a Direct connection option, a sliding door in front of the USB receptacles is necessary, 1766st that just single receptacle is exposed to users at a time. When the door switch detects role change, firmware disable current role, and it calls stack initialization for each role, host or device.
It can be seen that Q1 that is being used is already a PNP configuration.

Sorry, I’ve forgot to write on this modification in above post. You’ll fine similar discussion on Microchip USB forum http: Maybe, the pins on your footprint of the layout is swapped?
Compare your schematic with Olimex’s http: Products Scj Events Support Videos. These cables are not so popular on the market, yet. For Host mode, you don’t need any extra circuit for device plug-in detection.
