Hello, If I mount a USB device on a windows machine, can the device in any reliable way create files so that they appear on the windows explorer? I know the device is mounted on Windows so that Windows should be the one to determine the contents. But is it possible or is this a clear violation of the rules? what happens if the device creates a file, resets itself (assuming it can do that by control over the data lines) to force reenumeration? will Windows see the new file?
Check Keil Samples. It's already there. Look for USB Mass Storage. To "notify" Windows that a modified file is available, try a Soft Dis/Connect Sequence
thanks. I already found it - using an LPC2478. I hope I get it to work...
Ulrich, I had a quick look in the data sheet of the LPC2478. Am I correct in assuming that a hardware change is necessary in order to allow "softconnect" to work (namely, an external resistor) ?
Ulrich, I think we have a problem with the hardware here, but anyway: are you saying the using the USB_Connect function should force a re-enumeration? I cannot tell as our hardware is probably at fault...
