Well, after a we of testing (!), I got various results with 10.2.
For sure, having 2 Profilific cables running at the same time (Consult & Innovate) make the things worse.
I told you I used 2.0.2.1 for ages for these 2 cables, it works fine up to 0.9.14.22.
Strangly I don't manage to get back this stable bahavior since all my various tests.
One of the major problems with Prolific drivers is they require a reboot each time you change the driver version.
This is maybe why I got mixed results.
Here is my hardware mapping:
COM1 Prolific USB serial (Consult)
COM2 Prolific USB serial (Innovate)
COM3 Agere modem (not used btw)
COM5 Bluetooth port (not used btw)
COM6 Bluetooth port (not used btw)
COM7 Bluetooth port (a COM client port port I added to test my Parani SD100 BT serial connected to Innovate LC1)
(I have HP integrated bluetooth module with driver 5.1.0.4800. It creates COM5 and COM6 automatically)
2.0.0.18 seemed the only version for which Logworks3 still works on COM2 when the 2 cables are plugged in (detection takes a while though). Yesterday, 10.2 detected the 2 COM ports but sometimes I need to unplug-replug and relaunch Nistune to get them detected (I force COnsult on COM1 and Innovate on COM2). COnsult COM1 is opened immediatly but COM2 takes a while to get the first values displayed (> 5 seconds), when it works ...
I got sometimes blue screen (IRQ .... LESS message) on Innovate disconnection (I always disconnect clicking the button, quit Nistune, then I unplug the cables)
2.0.0.26 (as known as the most reliable b/w the dodgy versions) works with Logworks3 only if only one cable is plugged in (!?)
Didn't try 2.0.2.1 again but I should maybe ...
2.0.13.130 (the receommended driver, the latest one) shows yellow marks on my Prolific cables. COuld you try this one Matt ?

I may try ATEN USB 2.0.14.156, changing the USB PID VID to match Prolific ...
On the other hand, I tried my BT serial Parani SD100. It works really fine with Logworks3 on COM7 with speed set @19200.
I don't manage to get it working with my diy Consult interface @9600 (which works fine with Prolific or direct RS232 Cable !). I don't understand why ... I attached the corresponding logs with Portmon.
FF FF EF D0 F0 is sent but no answer. I tried to send each byte step by step using LookRS232 but no answer ... this is strange b/c it works with Innovate LC1 !
