This is from the Native Instruments site:
Most USB cables are labeled with the two identification codes following the AWG (American Wire Gauge) standard:
The code ending with /2C (or X2C) shows the specification of the power wires in the USB cable (relevant for this test)
The code ending with /1P (or X1P) shows the specification of the data wires in the USB cable
The number at the beginning of the codes reflects the diameter of the internal wires:
AWG 24: 0.511 mm
AWG 28: 0.321 mm
Our tests have shown that you should always use USB cables carrying a /2C (or X2C) code beginning with 24 (e.g. 24/2C, 24AWGX2C, AWG 24X2C). As described above, this means the power wires have a diameter of 0,511 mm, which will reduce the power lost in the cable.
The NI-branded cables supplied with our products do not carry any of the AWG codes, however they are specified with the larger AWG 24 diameter to ensure the best performance with your Native Instruments device. Look for the molded NI logo on the plugs to identify these cables.
If your cable is showing a /2C (or X2C) code beginning with 28 (e.g. 28/2C, 28AWGX2C, AWG 28X2C), it is not suitable for use with our hardware devices and needs to be replaced.
So…you are looking for 24 AWG usb cabling. 28/24 is the common one as the 28 AWG carries data, and the 24AWG carries the power. 28/28 is a no go as your power wire will not be consistent for the instruments we use them on. So, you know now that NI carries them, as does several companies i,e, Belkin. Newegg also carries them. Hope this helps…good luck !
