Packet over Bulk-out end point,I don't receive Acknowledge packet over Interrupt(or even Bulk_in) endpoint.here is the code in Xamarin Studio using MONO library : public class MainActivity : Activity

I tried to code this communication in an Android application.In Android codes I can recognize GPS device when connected to tablet.there are 3 end-points.One Bulk_Out ,another Bulk-in and the third one Interrupt-in.When I send start session The device responds to the host, letting the host know the device is prepared for a conversation.Ġ0 00 00 00 06 00 00 00 04 00 00 00 37 C4 E4 AB Interrupt In (USB Transport Layer - Session Started) The host sends this first to the Garmin USB device, to tell it to prepare for a transfer. All data is presented in HEX format.īulk Out (USB Transport Layer - Start Session) Messages below are presented in chronological order. This section provides a sample communication session between a USB host and a Garmin USB GPS. This is part of section 6 of this document that show how host and device(GPS) do communication :

I try to read PVT(Position,Velocity,Time) record from an Etrex 10 Garmin GPS that its USB port is connected to Android tablet(Samsung Galaxy Tab S,Model SM-T705 supporting USB host function).First I used a Windows application to simulate this communication and I monitored USB sent/received packets.According to Garmin documentation(Garmin GPS Interface Specification,USB Addendum),these data packets was sent and received successfully(all numbers are in hexadecimal):
