viRead error on unplug/plug USB Raw

[xavi]

When I unplug/plug my USB Raw device (either after or before opening visa session), I get a timeout expiration error on viRead. I can viOpen/Close session, viGetAttributes,... but in order to read data properly again I must perform a hardware reset. I could patch it executing a software reset, but I've not been able to discover how.

Any suggestion?

Thank you.
