The answer is a definite "maybe". One of the leading causes of USB 2.0 ports failure to recognize a connected device is the USB cable connecting the port and device.
However very high quality USB 1.1 cables might work but they are in a minority. The reverse is always true, USB 2.0 cables are fully compatible with both USB 1.1 and USB 2.0 ports.
There is no physical difference between USB 1.1 and USB 2.0 cables but the USB 2.0 cables are built to a much higher quality standard that meets or exceeds the requirements for the much higher comm speed of USB 2.0 and this is detected by the USB 2.0 port during hookup.
Thisresponse by Jeff Roberts, aka "USBman", explains the above.
The cable should be changed to a certified USB 2.0 cable if the error message "USB Device Not Recognized" is displayed while connecting the iHP series of players to your PC.
