(1) Driver installation on Microsoft Window 7 and Microsoft Window 8 can be performed automatically (on-line). It can happen that the first online driver installation attempt fails; in this case the user shall just force a retry (the second attempt normally works!).  The driver installed is NOT the Cypress generic USB device drivers (distributed with the Cypress SuiteUSB 3.4). but one of this two signed Cypress driver (they can be downloaded from Microsoft Update Catalog):

  • Cypress - Other hardware - Cypress USB Generic Driver (3.4.7.000) for BI15xx where xx is 00,11,12,14, 32
  • Cypress - Bus Controllers and Ports - ND-tech USB Adapter (Cypress USB Generic Driver, version 3.4.1.20) (link)
Note

The second driver could be used but it is not recommended because two PIDs are possible.

Same VID and two different PIDs are possible (written in the corresponding .inf file):

  • Cypress VID (0x04B4) and PID (0x8613) (are typically shown)

  • Cypress VID (0x04B4) and ND-tech PID (0x1004) (it is shown if the board is disconnected and reconnected without power cycle after the firmware download onto EEPROM: this procedure is not correct)
