If that's the case what do you call an SIO based interface that talks to ANY USB device?. IMO SIO2USB should be a general name indicating "Interface from Atari SIO to a USB device" (whether such interface exists or not), much like the USB interface on a PC. So Abbuc's device should have really been called SIO2USBS (USB Stick) or SIO2USBF (USB Flash drive) instead of monopolizing (perhaps unintentionally) the acronym SIO2USB.
At first.... I was referring to the fact that all the sio2 creations are talking to a STORAGE device. So bringing up talking to ANY usb device is a false statement. Any 'invention' using the 'sio2' name is talking to some kind of storage target. Like I wrote:
Sio2 PC -> Sio -> storage on PC
Sio2 IDE -> Sio -> Storage on IDE
... ABBUC is doing this with Sio2 USB
Sio2 USB -> Sio -> Storage on USB
Any compatible USB device can be used. If you have a compatible USB cardreader? connect it to your ABBUC Sio2USB and there you go.
It does not work with an USB scanner or USB speaker set, since that is not a storage device. And so it is not a problem that this device is still called a 'sio2' device.
That the abbuc SIO2USB is unfortunately not 100% compatible with all USB storage devices is a pity, but that is also with sio2IDE.
A sio based interface providing a 'real' USB port (compatible with all kind of USB devices) would not carry the name Sio2 ... but simply "Atari USB Interface"
Sio based Printer and modem interfaces also don't carry the name "Sio2Printer" or "Sio2Modem" right?
So Sio2USB is a perfect name in the list of "Sio2" devices.
