Hi,

I'm working on getting a WinUsb working. I have the device enumerating successfully. However, when I try to send data on BULK OUT to the device or read data from BULK IN in both cases I see 'incomplete' on my USB analyzer. I'm not getting ACK or NACK from the phy but the PC is targeting the proper endpoints. I'm also not able to hit the DataIn or DataOut interrupts when this happens.

Any ideas?

Porting issue. Seems like the EP_OPEN fxns have had some parameters move around.
