Handmade USB cables not working

[Stone Wolf 338]

Hello,
I am having some trouble getting a set of hand made USB connectors to work. A bit of background, the USB connectors are as pictured. The cables I am using are standard USB 2.0 motherboard connector extensions with the male ends snipped off and new female terminations put on. Those new connections will go to the pins that I have soldered onto the USB ports as pictured. My plan is to just use the available USB 2.0 ports on the MoBo to have everything hooked up.

The problem I am having is that when I test the ports with a USB drive nothing shows up. I have checked continuity with in each strand of the cable and everything seems fine. I have double checked the pin out for USB 2.0: R to Vbus, W to D-, G to D+, Blk to GND. I have not connected the shielding strand to anything.

I should also add that this is a new build:
gigabyte a520i ac mobo
gigabyte 4060 low profile gpu on a 20 cm extender
ryzen5 2600x cpu
16 gb ballistix ram
win 10 os

Any help is appreciated!

I cant see what you're doing wrong

Pick of cable ends that I made. Pick of the whole cable

All i can say is make sure you're inserting it in the right way into the motherboard.

You can use a multimeter in continuity mode to test if each wire goes in the right location and doesn't short with other wires or isn't broken somewhere along the cable.

These don't show the whole thing including the connector...

Sorry about that, the USB ports are mounted and hard to get to, but I did manage a ( rather crude ) pick.
And just for completeness a pick of the pin connectors taken out so my work can be double checked.

I have done this too. From what I can tell their are no shorts and things seem to ohm out right. I don't know if their is a minimum or maximum aloud tolerance for these cables.

I'd take a multimeter and check continuity all the way from the USB connector's pins to the motherboard pins, some of these crimps look sketch, probably some aren't making contact.

Hello all,

I have not forgotten about this topic and have new information. I spoke with a co worker about how to replace the cable ends and have ordered the crimping tool I will need. I will update more after  my order comes in.

*edit* And yes Kilrah, the connection were spotty. Just wiggling the cable a bit while testing caused connections to fail.
