Isochronous USB Issues¶
It seems there are many XHCI implementations out there that have problems properly computing the isochronous bandwidth limits and hence refuse to activate both icE1usb interfaces.
| System/Board | USB Controller | Runs with 2 icE1usb interfaces |
|---|---|---|
| Raspberry Pi 3B | built-in | YES |
| Raspberry Pi 4 | VIA XHCI | no |
| Thinkpad x260 | Intel Corporation Sunrise Point-LP USB 3.0 xHCI CoStroller (rev 21) | no |
| PC-Engines APU2 | AMD GX-412TC SoC | external:no, internal:YES |
