All this talk of ACPI and USB3 incompatibility is just vanilla XP and not using the unofficial ACPI 2.0 or USB3 drivers or XP2ESD correct?
That's correct from my point of view. Some Asmedia USB 3.0 controllers do have Windows XP drivers, but my board uses Intel controllers (not a huge loss since the board's USB 2.0 controllers still work fine with Windows XP).
I'm a bit of a purest, so I prefer to run the Vanilla Kernels or those updated by MS. But, that's just me. I don't mind unofficial drivers, though, as long as they're stable.
Personally, my father and me were an early adopter of USB 3.0 and we've started with PCIe add-on cards for USB 3.
This was in ~2010, if memory serves.
The earliest cards had the NEC chips on them and shipped with XP drivers for XP SP2 and up.
They worked just fine for the USB 3 HDD enclosure we ordered from a foreign country.
Edit: Because, USB 3 tech was almost unheard of at the time.
In ~2010/2011, in my city, no shop/store I had visited had USB 3.0 peripherals for sale.
The dudes selling electronics stuff had no idea what I was talking about when I asked for USB sticks/pen drives, card readers or external HDDs with USB 3.0 interface.
They all did stare at me as if I was some sort of a mental.
Then, they did show me cheap USB 2.0 stuff. I was so disappointed! 🙄
The only problem I can remember, of the early drivers, was, that sometimes the HDD was detected as USB 2 ("This device can provide a higher performance if" message popped up in taskbar).
If that happened, we unmounted/ejected the USB 3 HDD and removed/attached the USB3 plug.
It then was detected correctly as USB 3.0 HDD.
Other than this, I don't remember any trouble with USB 3.0 and XP..
Rather, the contrary. Most otherwise troublesome USB 1.x/2 devices worked like a charme on USB 3 ports.
They also provided more power, which was good for devices that exceeded the limits of prior USB specs.
A few months/years later, NEC was bought by another company, sadly.
They continued producing their chips, but.. I don't know.
I always felt the NEC versions were more substantial.
Edit: The Intel USB3 controllers are or were poor, I recall.
From what I remember reading 10 years ago, Intel was lazy or incompetent:
The company didn't include the USB 2 legacy block into silicon, as recommended by the USB IF.
Instead, Intel did leave the task for providing backwards compatibility up to the USB hub.
That's why there's so much trouble with USB3.0.
The Intel chips are (or were) purely USB 3. It's not detected by older operating systems thus.
Notebooks and PCs with USB3 integrated into intel chipsets have issues booting Windows XP/Vista/7 Setup from USB pen drives.
Unless they still have a dedicated USB 2.0 port left.
