Subject: Tech: USB Type-C cable upgrade 2022 From: Stilly River Sage Date: 01 Sep 22 - 11:11 PM I looked around at the various Tech: threads and didn't see a good fit for this. USB-C to hit 80Gbps under updated USB4 v. 2.0 spec You’re going to need new cables and learn to recognize revised logos The USB Promoter Group has announced version 2.0 of the USB4 spec and promises it can carry data at 80Gbps. There's more at the link. There are many more tech topics than cables, but this is a good starting point for this decade. |

Subject: RE: Tech: USB Type-C cable upgrade 2022 From: Stilly River Sage Date: 02 Sep 22 - 12:41 AM When I ordered this Dell desktop a couple of years ago I got lots of USB ports, but couldn't seem to find all of them until I realized the tiny ones tucked in front and back were the C ports. I have cables to use with them, and those older ports won't be any faster with the new cables (that I'm aware of) unless I swapped out cards inside or something. |

I well remember one of our users finding she couldn't use a certain external peripheral with her iThingie, despite both ends of the connection being the same USB version. Eventually we discovered the connecting cable was more than two USB versions behind, replaced it, and lo! one working peripheral. |
Subject: RE: Tech: USB Type-C cable upgrade 2022 From: Stilly River Sage Date: 02 Sep 22 - 10:11 AM I have several baskets in the office closet with labels for the old devices that are in them. Power supplies (sometimes they have a new life with a device I find at an estate sale or thrift store), cables, and adaptors are all held onto for quite a while, though I have thinned on occasion. On a shelf near my computer is a collection of the most recent adaptors for cables and devices that I use now. And those C-type cables are well-represented there. So far my uses are small - phones and tablets, but I have external hard drives that might benefit from faster cables (if the computer and the drive recognize that that's what they are and respond properly). |

I added a couple* to my 10yo Intel desktop that way - they were USB 3.0 type A (blue) but maybe there are faster or type-C ones now. * "Dual 2 Ports USB 3.0 A Type Female to Motherboard 20 Pin Female Header Cable" |
Subject: RE: Tech: USB Type-C cable upgrade 2022 From: Stilly River Sage Date: 03 Sep 22 - 02:01 PM Dave, I know - the motherboard can be a wealth of surprises. Just because the computer they sold has X number of USB ports or other features, it doesn't mean they exhausted all of the possibilities available on the board itself. If you visit the Dell service Manual and go to page 12 you see the Service Board (no results when searching "motherboard" these days). Lots of SATA 6 plugs though they may be in use. There used to be a small array of extras inside on other computers and while I've used those in the past for external hard drives I haven't even considered what I might connect to any of them today. Plugging in a cable that can handle high speeds is always preferable. |
Subject: RE: Tech: USB Type-C cable upgrade 2022 From: DaveRo Date: 04 Sep 22 - 03:06 AM From the spec of the XPS 8930 I see that two of the USB ports at the back - one type-A and one type-C - are faster than the others, and faster than the type-C port on the front. |
