Description
|
IOCTL_Ezusb_RESETPIPE
|
IOCTL_ADAPT_RESET_PIPE
|
Direct equivalent
|
IOCTL_Ezusb_ABORTPIPE
|
IOCTL_ADAPT_ABORT_PIPE
|
IOCTL_Ezusb_SETINTERFACE
|

IOCTL_EZUSB_GET_CURREN T_FRAME_NUMBER
|
IOCTL_ADAPT_GET_CURRENT

IOCTL_Ezusb_RESET
|
IOCTL_ADAPT_RESET_PAREN T_PORT
|
IOCTL_EZUSB_BULK_READ
|
IOCTL_ADAPT_SEND_NON_EP0
_TRANSFER / IOCTL_ADAPT_SEND_NON_EP0_DIRECT
|
Indirect equivalent.
CyUSB3.sys has two IOCTLs to implement non-control transfer rather than the ezusb.sys method of having one IOCTL per transfer type and direction. So all non-control transfer based IOCTL of ezusb.sys map to two IOCTLs of CyUSB3.sys
|
IOCTL_EZUSB_BULK_WRITE
|
IOCTL_EZUSB_ISO_READ
|
IOCTL_EZUSB_ISO_WRITE
|
IOCTL_Ezusb_GET_DEVICE_D ESCRIPTOR
|
IOCTL_ADAPT_SEND_EP0_CO NTROL_TRANSFER
|
Indirect equivalent.
CyUSB3.sys has single IOCTL to implement control transfer rather than the ezusb.sys method of having one IOCTL per type and one IOCTL per standard request. All control transfer based IOCTL of ezusb.sys map to single IOCTL of CyUSB3.sys

IOCTL_Ezusb_GET_CONFIGU RATION_DESCRIPTOR
|
IOCTL_Ezusb_VENDOR_REQU EST
|
IOCTL_Ezusb_GET_STRING_D ESCRIPTOR

IOCTL_Ezusb_ANCHOR_DOW NLOAD
|
IOCTL_EZUSB_ANCHOR_DO WNLOAD
|
IOCTL_EZUSB_VENDOR_OR_ CLASS_REQUEST
|
IOCTL_EZUSB_SET_FEATURE
|
IOCTL_Ezusb_GET_PIPE_INFO
|
IOCTL_ADAPT_SEND_EP0_CON TROL_TRANSFER, IOCTL_ADAPT_GET_ALT_INTER FACE_SETTING
|
Indirect equivalent.
Parse the interface descriptor of the device to populate the output buffer with data of the PUSB_INTERFACE_INFORMATI ONstructure that will be returned by ezusb.sys
|
IOCTL_EZUSB_START_ISO_S TREAM
|
IOCTL_ADAPT_SEND_NON_EP0
_TRANSFER / IOCTL_ADAPT_SEND_NON_EP0_DIRECT
|
No direct equivalent
ezusb.sys implements streaming on isochronous endpoint at the driver level. While CyUSB3.sys provide single IOCTL to send/received Isochronous packets.

IOCTL_EZUSB_STOP_ISO_ST REAM
|
|
IOCTL_EZUSB_READ_ISO_BU FFER
|
|
IOCTL_EZUSB_GET_LAST_ER ROR
|
N/A
|
Windows Win32 API GetLastError() API provides the error code for last transfer.
