USB hub 1.1 vs. 2.0

[blahsome]

Is a very simple (not self-powered) USB 1.1 hub materially different from a 2.0 one, provided it's connected to a true 2.0 port?

Thanks.

If "2.0" means it's a HIGH SPEED capable USB 2.0 hub, then yes, that's your difference. USB 1.1 had no "High Speed" mode, top speed being 12 megaBIT per second. High-Speed mode is 480. So if you're going to connect High Speed capable storage, then yes, it's going to make a big difference.

Peter is right on - the hub is itself a USB device (it is read separately by Windows as such) and a 1.1 hub is just that. It will work connected to a 2.0 port, but everything connected to the hub will be 1.1 speed.

I had my iPod using a 1.1 USB port, but it became frustrating watching 1500 songs downlaod so slowly. However after buying and installing a USB 2.0 PCI card, the transfer is outstandingly quick.

Mind you I have an old P3 so don't ask why USB 2.0 isn't onboard.

To add sometimes when adding a USB1.1 device in a USB 2.0 port with other Hi-speed devices connected it'll slow them down

Not really ... at least no more than the bandwidth it consumes on the uplink from the hub - and that'd be the same if it were "high speed" on its own connection.

Well my CD Burner and HD slowed down to a crawl when I hooked up a USB1.1 device to the hub it was running on...after I disconnected it all was back to norm.

Well the hub shouldn't (!) switch its uplink back to 1.1 speeds ever, regardless of whatever is connected on its downstream ports. You seem to have one that does ... spend $3 more next time 😉

Would it work if I connect a USB 2.0 hub to an old computer's USB port that is likely USB 1.1? Of course, I expect it to work at USB 1.1 speeds.

I have an extra USB 2.0 hub that I need to give away to someone whose computer only has a couple of USB 1.1 ports

Thanks,
