(true)MIDI USB Board

[Synthex]

Could you try this :

In "Propriétés de Périphériques audio USB" :
"Pilote", clic "Mettre à jour le pilote..."
"Installer à partir d'une liste ..."
"Ne pas rechercher. ..."
Select "Périphérique audio USB" and "suivant"
"Terminer"

[Synthex]

Does it work ?

[Zakir'S]

I already try this...
It doesn't work.
I will test megadrum with another computer tomorrow, to be sure the problem comes from my laptop or the driver.
Could you give the files installed by windows for such a device to compare with mine?

The last is : "wdmaud.drv"

[Zakir'S]

The drivers installed are exactly the same as synthex ones...
I try to install in another computer and it doesn't work.
Is it possible for windows to detect megadrum even if the PIC is not well programmed?
Because of Winpic error messages, I have some doubt about the programmation.

The only way to check it is to re-program your PIC18F2550 again.

Please try this :

In "Propriétés de Périphériques audio USB" :
"Pilote", clic "Mettre à jour le pilote..."
"Installer à partir d'une liste ..."
"Ne pas rechercher. ..."
Select "Périphérique audio USB" and "suivant"
"Terminer"

What do you think? Is that correct?

[dmitri]

In the Options tab->Programmer options are the first 6 boxes checked?

[Zakir'S]

Yes they are
