I had that issue with a USB HDD, finally put it on the jack nearer the board, the one on top was said to be for lower current. That worked.
But all in all, this is going into specific territory, the same solution may not work for everybody.

Data transmission considerations just need to be met with a USB cable. That's easy. All the digits will get through just fine.
It's the second order effects that lead to sound quality differences in my opinion. You are connecting the ground of your RF generating digit provider to your precious, sensitive audio system. RF does not behave like DC or low frequency AC. It respects only characteristic impedence and geometry. Unless your system ground is infinitely low impedance (at RF!) you will get RF voltages developing. Do they matter? In my experience, yes. I've clearly heard differences with different USB cable geometries using the same cable just from improving RF rejection on the Gnd and +5V line.

Of course, they matter. Correct RF termination of the shield wire is crucial... and not easy to execute.
The KSUSB-AG is a no compromise design. The highest grade aerospace materials are incorporated into the KSUSB-AG for unmatched performance.
Dye-free wrapped air- articulated PTFE dielectric provides the highest degree of impedance uniformity and dielectric performance related to loss and delay. 100% pure silver signal conductors provide near lossless signal transmission (up to a 6.5 meter length.) The over braided shielding with 95% coverage (44awg copper with 8% silver plating) is circumferentially bonded to the USB connector shell with pure silver foil for maximum shielding performance. The 5V DC line is comprised of 4, 24AWG pure silver conductors. In many DAC implementations that don't utilize this 5V DC line these conductors are used to augment the ground plane. In these circumstances these pure silver conductors will push noise levels even lower. With a powered device you will see very low voltage drop on the 5V DC line.
These carefully executed details deliver sonic performance with no compromise.
Hi there! I'm pretty new to this forum and found this very interesting thread. I have successfully build my own USB cable for my DAC. I built it using pure 999 silver conductors and separating the power delivery by adding a different external connector that is directly soldered to only one end of the usb.
I am using it in my system and although I don't have great speakers I can still hear a slight improvement. Here I'll upload some pictures and renderings I made to show the design.
What do you think about it? I'm curious to hear your opinion.

What software did you use to render your images? [ This is much a more impressive achievement than the cables themselves !]giova_dan:

Ahahah thank you, yeah took some time but wanted to experiment with that and I'd like to sell it if possible so I though it'd be useful.What software did you use to render your images?
I used Blender for rendering and some modelling and Rhino7 for the more precision modelling, the braid itself was made with grasshopper, with the Peacock plugin it's really easy.
But yeah about the cable I followed what I found in the internet, and came up with this version of my own. Don't know about capacitance and inductance but I guess since the signal is very low current that shouldn't matter so I focused more on the shielding.
If you find mistakes in the constructions or things I should have avoided / done differently please let me know since I'd like to make another one in the future, maybe thicker with cotton insulation and then braided shielding on the outer layer?
