Long USB cables

[GRL]

Are there long USB cables (I mean about 30 feet long)? If yes, where to find
them?
Thanks.

Thank you.
So, I need at least 2 hubs with 5 m long cables to reach the distance I want
(10 m/32 feet).

No, you do not need 2 hubs with 5m long cables to do the job but you do
need _some_ hardware. One way to do the job is to convert the USB
signals into some other format at one end of the link and then convert
it back at the other. One example of several products which can do this
job is at http://www.usbfirewire.com/Parts/rr-47-2014.html which will go
far further than your 10m requirement. There are probably less expensive
devices to do the same job since the need for this is so common.

 

[GRL]

Thank you, very interesting devices.
Could someone suggest similar, but less expensive products?

[Noozer]

Why not just tell us what you are trying to do?

If you will Google for "USB OVER CAT5" quite a few hits turn up. For
example there is http://www.networktechinc.com/usbc5.html
which, at $55, isn't cheap but is getting closer, at least if you
dislike the idea of the clutter of a daisy chain of USB cables and
powered hubs and the hubs' power supplies etc. I suspect that one could
eventually track down the source of some of these devices in China or
Taiwan and find an even cheaper source but that is left as an exercise
for the reader. ;-)

Thank you, John.
This price is more reasonable.
BTW, many times, in the newsgroups, someone (properly) reminds that it's
sufficient to search by Google to find the answers without asking for them
in a newsgroup. I think that it's not true that by Google is so easy to find
the best answers, as, instead, it's more probable in a newsgroup.

I have cleaned up the mess caused by intermixed top and
bottom-posting. Now at least a reader has a chance of
understanding it.

Please do not top-post. Your answer belongs after (or intermixed
with) the quoted material to which you reply, after snipping all
irrelevant material. See the following links:

If you don't know what to search for, it might be true, but
also consider the amount of time it took to get answers and
having to keep rechecking for them.

I just did a *Froogle* (damn Google for changing things)
search for a "USB Repeater" (not "extension" as the keyword)
http://www.google.com/products?q=USB+2.0+repeater&hl=en&show=dd&scoring=p&sa=N&lnk=next&start=50

and 20 seconds later found this (you'd need two of them if
the USB peripheral cord isn't long enough to make of the
remainder of the length)

Interesting find. I guess they use the USB's own power line to operate
the signal regeneration circuitry. That would reduce the available
current at the other end a bit but probably not enough to matter in most
cases.

Just to extend an USB cable...

That wasn't really the question -- Rather, what are you putting on the
end of it?

If you're connecting a device that uses a bit of power and no data, just
buy one or more USB extensions and go nuts.

If you're planning to connect a hard drive which runs at full-speed and
uses slightly more power then the USB spec requires, you'll need an
active solution.

Anything else will be somewhere in the middle.

 

[Noozer]

Then why can't you just use a piece of string, or telephone cable?

 

[GRL]

Ok, thanks, I thought that every extender had to be powered. I need it to
connect a notebook to an ADSL (powered) modem 10m/32ft away.

Oh, then why not just get a wireless card and wireless
access point or router? That is the normal way of getting
the job done.

Doesn't this modem have an ethernet port? I don't remember ever seeing one
that didn't. That would solve your problem right there.

Of course, but sometimes (maybe due to some interferences) using wireless I
found many problems even only between the room of the access point and
another one when I have the PC (continous disconnecttions and
reconnections).
Thanks.

Of course, but I'd need a cable also in this case (see my answer to Kony on
using wireless)!
Thanks.

Of course, but I'd need a cable also in this case (see my answer to Kony

But it would just be a $6.00 cable that would work without any problems,
instead of a bunch of junk to try and get the inferior USB to do the same
job.
