RE: [Libusb-devel] usb_release_interface() + usb_close() -> broke communication

[Martin V. <mva...@me...>]

Hello,
My 2 previous email seems too large!
Now, I know exactly the cause of the problem, so I do a resume...

The Bulk Transaction with some data must toggle between the DATA PID
DATA0 and DATA1. (Ref USB Specification 1.1 or 2.0)

So, when I Release the interface, do a usb_close, do a usb_open and
re-claim the interface, the software resend by default the usb bulk
command with the DATA0 even if the device is expecting it on the DATA1?

Question: Is there a flag somewhere in LibUSB that keep tracking of the
DATA PID to used? 

Thank's
Martin
