Cross-platform program to handle USB devices of a specific vendor

[enrico5th]

The devices will be handled as mass storage USB class devices, FAT32 formatted.
As far as I know they don't use a specific USB protocol so I think that only bulk transfer will be implemented.
I know these information are quite approximate, but this is what I've got up to now from the
Chinese partner.

Try to use functions from setupapi.dll. I believe it should work. You need to use OS specific functions.

Functions from setupapi.dll will work only for windows I guess, but I need to make a program that
works on Windows, Linux and Mac. I thought I could use some kind of a cross-platform USB library
(supporting the hotplug), but I don't know which...

If they appear as mass storage devices, can't use simply use file operations to write data onto them?

I don't think so, I need to recognize the device once it is plugged in and then
provide a number of operations including the file exchange.

When you plug it in, it will either be a block device or a serial device which has to be identified by your kernel. You may need drivers. After that your OS will expose it yo you through the various usb interfaces - either mass storage or serial usually. At which time, you are at least looking at a kernel device. This isn't a Qt issue at all.
