USB hubs - 2 questions - Tilted Forum Project Discussion Community

Redlemon · 02-02-2005, 01:19 PM

I'm looking for a good quality USB 2.0 hub, 4 or more ports, powered, for use on a desktop computer (a Mac, but that shouldn't make a difference). I have two questions:

* I saw a statement on one review site that if you plug a USB 1.1 device into a USB 2.0 hub, the entire hub slows down to USB 1.1 speeds. True or false?

* Are there any manufacturers to look for or look out for?

1) ive never heard anything like that.. but i could see if you plugged the usb2 into a usb1 it would slow it down..

2) not to sure on this one

Belkins are good. Thats about all that I have used.

If its USB2, the whole bus is 2 and anything 1.x will only go as fast as it will allow, the others will go full speed.

Yeah, I figured the 1.1 vs 2.0 thing was bogus, but I wanted to make sure before I made a purchase.

if your computers usb is enhanced i.e usb2 then your new hub will run at 420mbs but if it is only usb 1.1 then it will run at 12 mbs...

False. I think what they meant to say is that each usb peripheral will run at their given throughput which depends on whether it is 1.1 or 2.0 compliant.

Actually, I found the quote again, from this Amazon review:

Quote:

Second, the included documentation says that the hub will revert to a USB 1.1 hub FOR ALL DEVICES if you have any USB 1 device connected. It says that to get USB 2.0 throughput, you must disconnect all USB 1.0 or 1.1 devices from the hub first.

I think the commenter was smoking crack, but I wanted to make sure.

Nope, wait, I take that back. Here's from the D-Link webpage:

Quote:

Connecting USB 1.1 devices to the DUB-H4 may cause all USB devices connected to the hub to work at USB 1.1 speed. To ensure 480Mbps throughput for your USB 2.0 devices, don’t connect USB 1.1 and USB 2.0 devices to the hub at the same time.

I guess it is possible, but not typical, and that is just a cheap version.

I've been using Belkin Hubs with no problems. The last one I got had 5 outlets on the side and two on the top. It is small and looks good. unfortunately, the model number was on the box which is now long gone.
