PortA reset zero after USBINIT / Service ?

[mister_e]

There's no problem like that here.. post your code, PIC#, Schematic... all you have on hand.

Hi mister_e,

are you from Melab, because u wrote it like u are ?

Now i can say that this failure only appears if I use composite devices.
Such as keyboard and mouse. Therefore I modified the the usb18.asm
a little bit, because melab don't support composite. (reportdescriptor x2)
The device works good but not the 1-2 seconds after plugin in.
Seems like it do some reset or overwrites something.

Have you done something like this before ?

regards

ps. 18f2455, 2550 ...

Nope i'm not from Melabs. I'm just a long time enthusiast and user

Interesting problem so far... nope i never tried the composite stuff in my lasts USB projects... but it's sounds interesting. if you want, post it here for the community and experts benefit or in ZIP on my e-mail.

Done now, some mistake in the asm firmware solved.
Now i have 1xCDC, 4xHID working at same time in one device.

Seems the chip dont like twice endpoint resets
