[Libusb-devel] Control transfers

[Nuno S. <ns...@ed...>]

Hi,

Today I was doing some experiments on control transfers with libusb. I  
was setting a custom request to process on the device side,
and then invoking a control transfer on the host side to activate that  
request.

I was getting pipe error on the transaction.

My device is only composed by a unique custom endpoint but I was  
assuming the use of the default control endpoint.

Why could this not be working? What can possibly be the most direct  
cause?

Any tips?

Thanks,

Nuno
