Really long Descriptor

Post by Maui » Tue Sep 07, 2010 4:16 am

Hi there,

i am currently trying to push out 3840 bytes long descriptor and it seems that vusb is not able to handle that altough I have enabled the LONG_TRANSFER flag.
Is it possible to chunk write a descriptor just like with usbFunctionSetup() and USB_NO_MSG?

Greetings,

Maui

Yeah, I found that to be a bug.

You can make the change your self, but should be fixed in the next release. Are you trying force Feed back?
