We are using Windows 7 in our computer. We want to format the Mini2440 for WinCE. Serial Communication is ok. But when we execute the dnw.exe Usb:x appears.
Usb:Ok Problem
Maybe, you didn't install the USB drivers required on your host. Look for secbulk.inf and secbulk.sys or usb_driver.zip I think there is a newer way of doing it, but there appears to be some recent posts about problems finding the right application.
