assume that you have 2 platforms with usb support. In fact, one
device and a PC.
On the first platform, you have a USB device attached (e.g. a memory
stick).
You connect the platform with the PC through their usb ports.
Is there any way you can control the memory stick through the PC?
(The first platform will act something like a USB relay?).
Its not mandatory that the platform can access the USB device at the
same time. I can even have 2 different firmwares, one for normal
use(ttyUSBx) and another as a Linux Hub. How can I make mt platform
behave like a usb hub? (I have no experience in USB, any hints are
welcomed).
To me this seems like a very dangerous thing. The PC software will
assume that the data on the memory stick is unchanged unless it is
plugged out and re-discovered. So if your device works as a hub and
under the covers accesses the memory stick, the PC will easily fail or
corrupt the data on the stick.
