USB _is_ a well-designed hardware plugged directly into your PCI bus.

- denkmoon 4y agoWait until you see the how many attacks can be carried out using Internet Protocol.
- worthless-trash 4y agoI'm also not the one making the claim that its well designed either.
- rasz 4y agoUSB is purely pooled by the host, no Bus Mastering, no DMA. Bunch of frequent interrupts (125us uSOF) that need to be handled by the CPU. USB 2.0 is so heavy its mere presence in a computer (idle pooling something plugged in) visibly slows down any <1GHz computer (halving IDE transfers for example https://www.vogons.org/viewtopic.php?t=89651 https://www.vogons.org/viewtopic.php?t=89651). Users didnt notice because 2.0 started showing up in 2002 together with >2GHz CPUs.
