What is the difference between the WinUSB and nrUSB drivers?
« on: August 29, 2011, 05:43:19 pm »
Hi there,
Following the USBOsrKitDemo samples, I have the option of loading the WinUSB or the nrUSB driver, but it is not clear what is the difference. Any help will be appreciated. Thank you.
Jorge

Hello

The most important differences are following:

1) Size
   *) nrUsb has very small size ~ 180Kb.
   *) WinUSB has very big size 11Mb.
2) API
   *) nrUsb is simple generic kernel USB driver with our original API. You can work with this driver only over nrComm Lib or nrComm NET.
   *) WinUSB is well know Microsoft framework. You can use installed WinUSB driver from other applications and projects that are compatible with WinUSB API
