Having just used some benchmarking s/w to see which motherboard I have prior to getting more RAM (c/o another thread, thanks...) it tells me I have one USB 2.0 port, how do I know which one that is as I would ideally like to use that one for wireless network card?
 
As Chris said, one USB2 port may be all ports.

To confirm, consult motherboard manual, if it has usb2, then all ports will be the same.
 
One USB "port" = 2 sockets

If you only have 2 sockets they are both USB 2

However, If you have a motherboard like mine, that has 3 USB ports, not all of my ports are USB 2 ... two of them are USB 1.1

If you can tell us the make of motherboard we'll be able to tell you what you have.

Well you learn something new every day don't you...
 
Its an ASUS P4S533-E, as I recall Everest Home Edition tells me only one is usb 2.0, there are two on the back of the box and two on the front, plus another one on the front that looks like a slightly squashed USB port, whats that? Even if I am sure how many the MB supports how do I know which is which?
 
Look at devices ...

The easy way ... plug a USB 2 device in and whatch XP moan at you for doing it the wrong hole. ;)



Chris ... you being sarcastic? ... no room for two of us. :p
 
the squished one ( I love those technical terms) is likely a firewire port, may not be hooked up.

As for xp moaning, most likely not. Most usb2 devices are backwards compatible, and will run happily at 1.1 speeds, at the slower rate. Only some very high performance video capture type devices won;t run at 1.1. Nics and most keys, usb hdd's all run at either speed.
Only way to tell as far as I know is to use a usb benchmark to test a device and look at the transfer rate and reported mode from the device.

Or as some wise man once said, Read The Fine Manual. worst case is that the off mobo ports are plugged to headers and you would have to trace the cable from the front jacks to see where they go.
 
XP USB 1.1, and pluging in a USB 2 device ... XP will "moan" and say somthing like ... This High speed device may not work at the speed it was designed for ... bla bla bla.

Try it ... XP will 'moan' at you ... ;)
 
Actually I got the "ports" bit wrong ... but they are usually in pairs on the MB headers. :D




Err...no? I just meant i didnt know that lol

Well that's OK then.

:D
 
strange, my xp pro has never said a word when I plug my usb2 hdd in, and that mobo only has 1.1. Maybe there;s a setting for that I turned off, I hate nag messages.

If you hate the 'nag' messages, then you probably did turn 'em off.

I have 2 external USB 2 powered hubs ... one plugged into the 1.1 port and one into the 2.0 port ... now as they where both identical stacked hubs I was a little annoyed at myself ... so I just plugged in me kit. Now the ver2 USB/port/hub is marked with a CDR pen. :D



Does Linux 'care' what is where? :)
 
What is the speed of a 1.1 port then, if its more than say 8Mbits/sec it doesnt matter as I wont be getting that speed from t'internet anyway?
 
USB 1.1 allows a maximum transfer rate of 12Mbits/second.
usb 2.0 spec allows:
Full Speed USB is 12Mbits/second
Hi-Speed USB mode is capable of 480Mbits/second.
So usb 1.1 in theory will handle a 10mb broadband connection.
In reality, use an ethernet connection if you can for all broadband connections, they tend to be more reliable. If you dsl/cable modem only has usb, then use what you got.
