question about VID and PID in MPTool (Asmedia ASM235CM)

Thanks for your reply. But why is the name strange with the letter “e” at the end when the disk is ejected ?
It should be named after the product string “Ugreen Storage Device”

I'm now hesitating to flash with 200416_D1_48_02 my other three Ugreen enclosures which are my backups.
I'd like to know if this firmware is really stable without any problems.

Do we know the person who creates this new firmware ?

The firmwares are provided by manufacturers like Ugreen and of course created by the chipset manufacturer, so Asmedia for the manufacturer. 

Thank you for this information.
So there is no risk in keeping this new firmware over time ?

Do you have any ideas for the name of the ejector ?

No, there is no risk, the name E is probably due to the configuration file to be checked unless the E indicates the name of the drive E:\

here is the configuration file :
I don't seem to see the “e”
The product_string=Ugreen Storage Device is present, but is not taken into account during flash.
Perhaps the config file should be reset to default or is there no point ?
