[FONT=Arial][SIZE=2]I tested the "USBMem" project in the sample code, it works and the computer can recognise it as a USB Mass Storage device.[/SIZE][/FONT]
[FONT=Arial][SIZE=2][/SIZE][/FONT]
[FONT=Arial][SIZE=2]Is there any existing API calls can send/receive data to the computer? (assumed that computer side has an application to cope with)[/SIZE][/FONT]
[FONT=Arial][SIZE=2]E.g. in the current sample code, there are some function calls like "USB_WriteEP", "DataInTransfer"[/SIZE][/FONT]
[FONT=Arial][SIZE=2]Can I use these function calls to communicate with the computer? How to use them?[/SIZE][/FONT]

[FONT=Arial][SIZE=2]Thank you very much.[/SIZE][/FONT]

Sorry, I don't understand.

For example, I want to send several bytes to the computer thr the Mass Storage channel.
I see in the sample code, e.g. mscuser.c & usbhw.c, there are function calls like USB_WriteEP or DataInTransfer. I'm not sure which one is correct nor how to use.
So, is there any function calls can send several bytes to the computer?

Generally custom SCSI commands are used. IOCTL_SCSI_PASS_THROUGH can be used in Windows to send such commands. I think you can change MSC_GetCBW() to add one.
