I might have exaggerated about my RGB configuration (that's another matter). I've run out of USB ports on my motherboard. I understand that external ports can be combined, letting heavy devices connect. Can I divide my internal USB slots? I assumed there would be demand for a PCI card with many internal USB connectors and some external ones. I've discovered a lot on Amazon and eBay such as: https://www.amazon.co.uk/Motherboard-Hea...NrPXRydWU= Or I could swap my spare internal USB 3: https://www.amazon.co.uk/SilverStone-G11...52&sr=8-15 But I haven't found any trustworthy sellers. I'm okay with cheaper options (and don't care about brands) unless you give me a green light. Ta A

Obtain an internal USB card header. The version you mentioned is a USB 2.0 to 3.0 adapter, not the reverse. This specific model may function. It's a specialized task, usually available only from certain vendors.

They're not splitters; they're referred to as HUBs. It's typical to find hub chips with 1 to 4 or 1 to 7 ports. The maximum number of devices per controller is generally 128, though remember a device can appear as multiple units—like headphones that function both as headphones and microphones, representing two separate devices. The hub chip itself counts as a device. The first link uses a USB 2 header with pins for two USB ports, connecting one USB hub chip to each. Each hub chip provides four ports (organized in two headers). This means you lose one USB 2 header (two ports) but gain eight USB 2.0 ports. However, the four ports on a hub share the bandwidth of the original port, so simultaneous use of all four won't deliver full 480 Mbps to each. This usually doesn't matter for RGB strips. The silverstone cable is more complex than it seems—it's designed to create a USB 3 header on older motherboards that only supported USB 2. Imagine an old PC with just USB 2 and an enclosure with two USB 3 ports front-and-center; the cable transforms the USB 3 connector into a USB 2 one, allowing connection to the motherboard. The front panel ports will function, but operate at USB 2 speeds.

I believed those adapters were completely ineffective.

Internal USB hubs aren’t as widespread as standard external ones with Type A ports, though they do appear and function similarly. RGB controllers typically require USB 2.0. Here are some options:
- https://www.amazon.com/NZXT-Internal-USB...B08L8VJS3Z
- https://www.amazon.com/BYEASY-Adapter-Re...B0919CDDN3
You don’t need to purchase these specifically, or buy them from Amazon; they’re just illustrative examples.
