I just bought a new PC, based on Lenovo Legion gaming desktop. It comes with 2 USB port in the front, 4 regular USB port in the back + 1 USB-C port. That’s a total of 7 USB slots.
It’s been like 2 decades that every possible hardware device comes with an USB interface. Keyboard, mouse, joystick, hard-drive, memory stick, headset, webcam, spot/photo camera, and many others.
Of course it’s my fault, I should have thought about USB connectors when shopping for a new PC and check before buying. but seriously, 7 USB slots is so few compared to all the device I have using USB
Those modern high speed USB controllers are not free. They used up available PCIe lanes. The more you add the less PCIe lanes available in the motherboard.
If you have a lot of low speed USB peripherals, just buy some large USB 2.0 hubs so you can reserve the high speed ports for high speed applications such as external disks.
