Meeeeeeep wrong !
The chips used on SubWay,HighWay and Algor are USB1.1 chips. The SubWay doesn't even reach full USB1.1-"highspeed" due to the limiting clockport.
But all USB2-devices have a fallback to 1.1 so there shouldn't be bigger problems except for the lack of speed.
No Kronos, the uhc124 chip used by Subway and Highway is a usb 2.0 chip but without high speed mode. Only low and full speed are usable.
The clockport is a bottleneck (8 bits) but the Subway react very quickly.
The OTG243 chip used by Algor is a true usb 2.0, got the high speed mode, but I doubt we can transfert anything at 480Mb/s...
