Hello,

    I want to use driver interface directly, and what's the difference between IOCTL_ADAPTER_SEND_NON_EP0_TRANSFER and IOCTL_ADAPTER_SEND_NON_EP0_DIRECT?

    Or can somebody tell me how to use cyapi.lib under VC++6.0?

   I tried to use cyapi.lib under vs2008 and it works well, but when I use it under vc++6, the linker complain it can not find some symbols.

 The first one is the buffer method of transfer and the second one is the non-buffer (direct) method of transfer.

CyAPI.lib currently available was compiled using VS2008 so I doubt you'll be able to use it with VC6. Please look at http://www.cypress.com/?id=4&rID=32529
