Hi there!
Do you want to know if you can get full USB 2.0 speed by installing an USB 2.0 host controller card into an old mainboard which already comes with an integrated USB 1.x host controller?

If so, then yes.. However, USB 2.0 at full speed is only possible if your USB devices do support USB 2.0, too. Also, the old ports are still USB 1.x.

Sorry, if I got it wrong. I didn't really understand your grammar. 😅

Yep sorry for it 😁. Yes you understood it correctly. I have a boad with an USB1.1 Controller. I am using an usb 2.0 stick to transfer data from my pc to this older one. But 1.1 is pretty slow, so i want to upgrade it with a usb 2.0 pci card to boost the data transfer.

As i understood you, this card should boost my usb 2.0 to full speed

Depends on the o/s you are using.

I feel the same, USB 1.x is very slow. 🙂

Yes.

I think the same. If atom1kk uses Win98 and the drivers from the manufacturer, it should work.
I did the same back in the 2000s when I had an Win98SE PC.

The cards with a NEC chip are sought-after, I think.
The Macintosh community uses them, too, if memory serves.
The ancient Mac OS 9 detected them as USB 1.x, but OS X detected them correctly as USB 2.0.

And when my father and me got an early USB3 card, it had an NEC chip, too.
This was early 2010, I vaguely remember, before Renesas bought NEC.
With the USB3 drivers from the manufacturer (NEC), Windows XP SP2 became able to understand USB3 just fine.
This was in a time before the public was aware of USB3.
Stores still sold that slower USB 2.0 stuff, which was inferior to Firewire aka i.Link. 😉

It is for win98se. Buuutt 😁 i am searching for a card with connection for the front header:D. This isnt quite easy task

98se with nec usb card works with 2.0 speeds.

Front connection is possible, you will need appropriate cables.

thx, i see alot of VIA cards, are they also compatible or do I need nec? I have already the header, but its hard to find a card wich has connections on it for the header

Via should work, my practical experience is limited to nec cards

See this thread: A (Very Short) Guide to Having USB 2.0 in Windows 98 SE with a NEC-Chipset USB 2.0 PCI Card

And remember that low performing systems do take a noticeable performance hit with a USB 2.0 card installed.

Have used a VIA USB2 PCI card even with a Socket 7 AT motherboard, and it just works.

The consensus in this thread is that the NEC cards work more consistently than the Via ones. Which USB 2.0 cards for old motherboards
