Android Question usbserial with 4 port

[logicielrl]

i'm using usbserial lib with 4 usb devices

Sub Process_Globals
Dim usbt1 As UsbSerial
Dim usbt2 As UsbSerial
Dim usbt3 As UsbSerial
Dim usbt4 As UsbSerial

Dim astreams1 As AsyncStreams
Dim astreams2 As AsyncStreams
Dim astreams3 As AsyncStreams
Dim astreams4 As AsyncStreams

End Sub

Sometime the stream from astream1 get receive from astream2

What would cause this ?

this is the sub im using for the astream

Sub Astreams1_NewData (Buffer() As Byte)
ListView1.AddSingleLine( BytesToString(Buffer, 0, Buffer.Length, "UTF8"))
ListView1.SetSelection(ListView1.Size -1)
End Sub

Sub Astreams2_NewData (Buffer() As Byte)
ListView2.AddSingleLine( BytesToString(Buffer, 0, Buffer.Length, "UTF8"))
ListView2.SetSelection(ListView2.Size -1)
End Sub

thks for your help

You need to show more code. How do you initialize the streams?
