I have a bootloader that update my firmware via USB.
The problem is that the current bootloader (or most) reset the uC after update.
I can't allow the uC to reset since the host application has a handle to the USB. I can release the handle and capture it again but preferably not. The other reason is, that this is a for product, and on USB release and connect, the PC (Windows) makes that sound that might confuse the product user.
I did post a similar message on Silabs forum since it is an Silabs device (although 8051) and USB related.
Is there anybody who would be so kind to help me with this problem please.
I will give more info, if necesarry.
Thnx in advance
Neither I or the user will be an idiot, only the guy who press the update button is an idiot, becuase there is no update button. The button is not a function a firmware update but a function of selecting an algorithm.
The user doesn't have to know an update is taking place. He only needs to know wheter initializing the new algorithm was successful or not.
1) Then tell him that "initializing the new algorithm" will make a noise when done
What is so terribnle about that?
2) what is o terrible about the user knowing "update is taking place."

Thanks to all of you guys. I know have several opinions and it seems to be OK if the USB makes the connect/disconnect sound during firmware upgrade.
Although I would have preferred it without the sound but will accept the sound as part of the upgrade.
Cheers
