usb cables, difference between 1.1 and 2.0?
hello
i know that you need a usb 2.0 chip, and usb 2.0 hub to enjoy 480mbps speed.
what about the cable? i have several 1.1 cables, they look like 2.0 cables to me. can i get 2.0 speeds using 1.1 cables?
thanks

For me, they all seems the same
Okay, i gt one USB cable to my Sony digital voice recorder, that end with the bulky shielding thing (like every ot DVI monitor cable...)
However the thing is USB 1.1 at most
IIRC my HP1012 has USB 2.0 capability, but comes w/o cable (!) and I just used the first cable come to my hands (perhaps the one was orginally made to connect my Motorola SB4200 cablemodem to USB port of computer?) and never had a problem with it...
Okay, the specs:

...did not say that the printer is USB2 either Just "Connectivity, std.
USB (compatible with USB 2.0 specifications)" so it might be not, I just judged from the very very high speed of printing that it should be (I get used to PowerMac and HP5MP printer, connected with the Apple serial bus, witch is kinda slow todays)
Well, my CF card reader is USB2 for sure (huge speed up on USB2 ports ), but the cable looks like the other are
So my quess that as long as things seems working, use the cable you got with the device
The USB thing is fairly simple. Data+, Data-, Ground and +5V are there. In all the USB 1, 1.1 and 2.0 ... From what I see on connecting the wires to mono connectors I bet that except using very long cables for USB2, no one should hit any problem with any working USB cable on USB2 speed
But that is just my assumption. Anyone could back up by reading the USB2 specs, there are will be for sure max. cable lenght and perhaps even some specs...

How they differ? I don't know what constitutes the difference in construction, but I do know that components using USB 2.0 work better with USB 2.0 cables. If you have USB 2.0 inputs on your computer, and a component is rated for USB 2.0, then you should be using a USB 2.0 cable.trodas wrote:JVM - could be But pls enlighten us, how do they differ
So far, I not spoted any difference, but I could be pretty much wrong
The difference in peformance is speed - I think
I have had some difficult experiences mixing USB 1.1 spec cables with USB 2.0 onboard/card connections. Although many non-2.0 rated cables will work fine, not all older cables/connections will work - it can hang your machine at boot when there is a problem, and other times plugging in the device will cause a system crash.
Best way to find out is just to try it out, IMO.
