Recent castle link software vs Mamba max issue

[Mister-T]

Hello,
I would like to tell you some issue that may happen with people there old mamba max with the last version of castle link (old enought so they have the old software that require direct USB connection).

To make long story short, I managed to solve the problem myself but I prefer to warn or ,at least, give a possible solution if people run in the same issue as me.

I own 4 CC product and decided to update all my ESC to the last software today.

1 mamba max pro via castle link ---> NO issue
1 mamba Monster V2 (still working :D ) ---> NO issue
2 mamba max ---> problems ...

1 mamba max date back MAY 2007 (updated to fw 1.21) while the other date back from 2009 (fw 1.17)

In both case I run into the same issue.

When I plugged them via castle link, it didn't work, connection couldn't be made as the software didn't support it. My bad ;)
So I direct connect it on USB .

In both case on my main PC (win 7), I heard the usb connection sound but driver couldn't be found an the ESC remain blank, no LED. I did the control panel / reinstall /update driver but windows couldn't find the file

epic fail ...

A reinstall as admin / reboot / run as administrator didn't fix the problem. I tried 3 different USB port, including one from self supplied hub --> fail


So I used my laptop. Under Win vista.
A old version of CC link was installed, both mamba max were detected and running ... closed apps but
I did kept the mamba max plug in (red and green led on) while updating soft to 3.30.3 !
While running the last software, esc is detected but I hear the plug sound of windows.
The esc just did shutdown !
Unpluged/pluged back , Ok led coming back, the software freeze for 4 second I've got a message about incorrect auto lipo setting, click ok,
then the application open a windows about the new firmware availability.

Let's go time for the update.

I see the led blinking
'phase 1' ok,
'waiting for the controller' then
"clink clong USB disconnect sound"
ESC SHUTDOWN
"clink clong USB connect sound" (I didn't touch anything)
LED Coming back
Phase 2 writing OK
Succesfull !
Then the "reading parameter" windows appear but the whole software is frozen
I right click on the CC link in task bar to close it.
A error message about USB connectivity issue and asking to unplug the device wait 30 sec then plug it back.

Even after the firmware update, the esc still on/off when trying to change parameter and upgrade the firmware via USB.

I tried to plug the ESC via castle link interface, everything is OK and smooth running.

It's maybe my computer (connect and detect driver file missing on my main PC ?) but still it looks like that direct USB connectivity as some reliability issue with recent version of castle link software.


EDIT

I did a test again, basically overwriting the last firmware, using onboard MM usb slot and last software on my laptop.
The update work (same pattern as above) but the esc shutdown afterward and software still freeze. Unplugin/plugin usb restart the esc and unfreeze the software as well.
This behaviour does not appear while using castle link interface.
