TE_USB_FX2_CYAPI int TE_USB_FX2_Close(CCyUSBDevice *USBDeviceList)

After the execution of this function, no internal handle inside of USBDeviceList is open. These handles are internally managed by CyAPI.lib and there is no need to expose them to the user. |

Other internal handles (inside USBDeviceList) are automatically closed by TE_USB_FX2_Open() function when another handle to the device driver is already open (i.e. a TE_USB_FX2_Open() has been successfully used before). It is a behavior inherithed by CyAPI.dll Open() function. |
This function takes an already initialized USB device list, searches for Trenz Electronic USB FX2 devices (any Cypress driver derivative and VID = 0xbd0, PID=0x0300) and opens (and immediately after closes) the first device found.
The selected module is not directly given by USBDeviceList (CCyUSBDevice type). An internal operation that opens and immediately after closes an handle to CyUSB.sys driver (or a derivative like TE_USB_FX2_xx.sys) is executed instead (see page 45 of CyAPI.pdf). The open method closes every other handle already opened, and close method closes the only handle open; in this way, all handles are closed. These handles are internally managed by CyAPI.lib and there is no need to expose them to the user.
