Title: Where on Windows host does USB device data transfer go ?
Post by: Golgo1972 on December 12, 2016, 07:28:34 pm

Any insight as to where on the Windows host (the drive path location) does the data that is stored on the USB device (USB video/pic camera) get moved to or transferred to ?

I have the winusb_cs/winusbdemo.exe running on Windows 10. I have taken pics and short video clip recordings with a Qualcom based Police body cam that the winusbdemo has correctly recognized. I do get 'Device found'. I do see the device metadata listed in the Winforms text area, but if I click on the transfer button to send data from the device to the  Windows host, where does this data go to ? Is it stored as .dat file  and put somewhere on  C:\Windows\.... ?

Thanks.

Look at the code for the call that reads the data. For example, if it's WinUsb_ReadPipe, the data goes into the buffer (the third parameter).
