A USB cable is a USB cable, the devices may be different speeds, but the cables are not...There may, however, be a difference in shielding:

The difference is in quality of manufacture (i.e. shielding) "...the original USB 1.1 spec for cables was perfectly adequate and met specification for USB 2.0. The trouble is that some vendors discovered that cheaper USB cables seemed to work with USB 1.1 devices and started manufacturing them that way. These cheaper USB 1.1 cables will not function properly with USB 2.0 devices."

"...any cable that meets the USB-IF's specs for USB v1.1 is also USB 2.0-capable. The USB-IF never issued any updated specs specific to USB 2.0..."

"...there is no USB 2.0 spec for cables..."

I think the message here is that if you buy a good quality USB cable, it will work well with a high-speed device.  If you buy a cheap piece of junk cable, it may not...And if you buy a cable with "High speed USB2" written on it, that does not guarantee you anything whatsoever.
