What steps will reproduce the problem?
1. using cheap BIGtec Big112 USB to serial converters (Prolific PL-2303
replica) under WinXP
2. opening one of the COM ports (with polling) in one QextSerialPort
application and waiting for input
3. calling QextSerialEnumerator::getPorts() every second in another
QextSerialPort application and updating combo box if changed
What is the expected output? What do you see instead?
expected: The already opened port should disappear from the list.
seen: The port is still shown in the list and reports an error when trying to
open it again.
What version of the product are you using? On what operating system?
v1.2, Qt 4.7.3, WinXP SP3
Please provide any additional information below.
I've read that WM_DEVICECHANGE only works for a small number of USB to serial
converters.
I've got the USB to serial converters connected via nullmodem cable. One app is
faking a Tektronix 4050 DMM and the other obtains DC volt values from it.
Online attaching/detaching works, communication works if the correct COM ports
are used.
