Description Uwe Hermann 2015-03-13 18:18:46 CET 
Some issue in libserialport and/or libsigrok's ols driver causes multiple acquisitions using an OLS (on Windows) to fail.

The first scan + acquisition works fine (since bug #562 is fixed), but when pressing "Run" again (at least) the following errors occur:

[...]
sr: serial: Read error (995): Der E/A-Vorgang wurde wegen eines Threadendes oder einer Anwendungsanforderung abgebrochen.
sr: session: sr_session_start: could not start an acquisition (generic/unspecified error)
[...]

Multiple acquisitions in a row via sigrok-cli seem to work fine and/or not hit this issue (since sigrok-cli "starts fresh" every time, I guess).

The 995 error sounds familiar, I think I've seen this with other devices as well on Windows, might be an issue in libserialport itself (not sure yet, though).

This looks like a libserialport rather than libsigrok problem, and more specifically like a duplicate of the issues remaining in bug #341.
