Just use a USB2.0 cable, the cables are identical, it's the same story with SATA cables.

this is not true USB 3.0 Cables are not the same as USB 2.0 they connectors are but the cable itself on USB 2.0 has 4 wires and USB3.0 has five more wires in it for a total of 9 so no they are not identical

Do you mean that I would be able to get USB 3.0 transfer rates using a USB 2.0 bridge cable? You sure about that!

 

No, USB 3.0 have much higher speeds than 2.0

 

Look for a belkin easy transfer cable. Im not sure if they have a USB 3.0 yet but basically lets you transfer files between computers with a USB.

If the computers are both running Windows 7 it has easy transfer built in and all you may need is a male/male cable.

The belkin cable you are refering to is a USB 2.0 bridge cable, which won't give me the transfer rates that I have with USB 3.0.

Using a male-male USB 3.0 cable is what I had thought of doing it intitally but then I read this:
Quote:

The first thing you should be aware of is that there are several different kinds of USB-USB cables on the market. The one used to connect two PCs is called bridged (or USB networking cable), because it has a small electronic circuit in the middle allowing the two PCs to talk to each other. There are called A/A USB cables that, in spite of having two standard USB connectors at each end, don't have a bridge chip and cannot be used to connect two PCs. In fact, if you use an A/A USB cable, you can burn the USB ports of your computers or even their power supplies. So, these A/A USB cables are completely useless.

- Source

So I am kinda skeptical from trying that to find out, but that article is quite dated and they are talking about USB 2.0 there, so I do not know whether USB 3.0 has changed anything on that front, but till I know for sure I'm not going to risk frying anything!

Thanks! I'm aware of that hence the specific question -
Quote:

Can we get 2 PC's hooked up via their USB 3.0 connectors? I know there are bridge cables which allow us to do this for USB 2.0 but can't find anything for USB 3.0, does anyone here know of anything which would let me do this?

Any suggestions / links / articles etc etc please.

Comparing both USB 2.0 and USB 3.0 cables - other than the buffer on these these cables controlling the speed, i would think these cables may have the same speed..The reason i say that i have seen 1.1 usb cables work as fast as 2.0 usb cables..

Can anyone weight in on this - saw this while searching the net, if that is true like overclocker23578 said

- then a USB 2.0 cable would work fine, wouldn't it?

Does anyone here know for sure?

 

usb 1.1 and 2.0 cables are physically the same, their connectors has 4 pins and the cable itself has 4 wires bundled together.
usb 3.0 is totally different, it's connector has 9 pins, the cable has 9 wires bundled together. get your facts straight.

look at the connectors, the blue one is the 3.0, notice the 5 extra connetors at the top next to the 4 pin connectors.

sata ii and sata iii cables are just the same, but usb 2.0 and usb 3.0 is not.
you won't gonna get usb 3.0 speeds if you use usb 2.0 cables
don't believe those people that doesn't actually have usb 3.0 system, they are just speculating things

Thanks for the information and the pictures but avoid the snotty remarks next time, or better just avoid answering.

Whew...I mean ... I was asking a question based on information I got from somewhere else on the net (probably another teenager like you who thinks he knows everything about technology because he built A computer) and that person also did not claim that as the absolute truth, he was testing out a logical hypothesis (if you want to get technical)! It could be right or wrong, so there are no facts here to get right - how full are you with ....yourself?

Did you forget to read the OP in your hurry to share the little bit of knowledge you have? Do you have a solution/answer for the issue posted there? If you do I'm all ears, otherwise spare me.

No I did not miss that, I ignored it, because it seems you did not read the OP. I very well know USB 2.0 and 3.0 standards are different.

If I did not then I never would have started this thread, it is because I want the 3.0 transfer speeds when 2 systems are networked using a USB bridge cable that I did not just go out and buy a USB 2.0 bridge cable which are plentiful in the market - like this one.

You or someone else telling me 4 vs 9 pins without explaining (if your knowledge permits) how that affects throughput or transfer rate or whether that difference eliminates the need for a bridge in the middle does not help answer my question. You were just eager to disprove someone else rather than provide a solution, so it was irrelevant to me.

Anyways as per this article it seems a normal USB 3.0 crossover cable can be used to connect 2 PC's together but they also say that no OS currently supports it, don't know how old that article is. But as long as it won't fry my system I will try it. I'm trying to find out where in the specs for USB 3.0 does that specify that this can be done as that site claims.

I'm still looking for a USB 3.0 (yes the 9 pin one) bridge cable - if anyone does know please do tell.

 

I was searching it and I didnt find anything.
I suggest using gigabits.

Yeah I'm kinda leaning in that direction too.

Only if I could find if the crossover cable linked above would work, without actually plugging it in to test, it would be great.

 

Okay I just called Datapro - company whose crossover cable I had linked above, and basically the guy said that this one is a better choice but as of now there are no 3.0 cables which would allow file transfer or networking (he knew what he was talking about).

This one is used for debugging mainly and no OS would support file transfer/networking over the USB 3.0 cable right now. So that kinda answers that. He said that they might have a bridge cable out soon, from one of their vendors.

Well I think we are close! Here is my thinking on this. All the warnings for not using a "crossover" cable are for connecting USB 2.0 to USB 2.0.

You want to use a USB 3.0 cable but without the USB 2.0 pins. I see two possibilities here, 1) remove all four USB 2,0 connectors
OR 2) remove just the two USB 2.0 connectors that are used to supply power, ~ 5.0 volts and up to 900 MA.

So if I had two computers with USB 3.0 adapter cards, I would buy a USB 3.0 Male A to Male A cable and remove the four connector pins
that are for USB 2.0 "compatibility" first. If that did not work, next try removing the two power connectors.

As to the software on Linux, the current software supports USB 3.0 and there is a (i think) a usb-net so that may be all you need.

My 2c.
I think if you have 3.0 on both machines & a male to male 3.0,you can create an ad hoc network?
Have thought about it, may be driver/device dependent...
My MB has built in and I also have an add in pcie type-not sure if they would "connect".
Pretty sure wont fry anything,but may not be able to use as connection device?

 

Here is a good write-up about USB 3.0;
http://www.cablewholesale.com/support/technical_articles/usb3_superspeed.html

OK, Datapro has updated their on-line catalog, there is NOW a USB 3.0 cable w/o the USB 2.0 power connections.
http://www.datapro.net/products/usb-3-0-super-speed-a-a-cable-crossover-strict.html
Quote:

Easily connect two computers together (or connect a PC to one of our dual-panel-mount A/A cables)
with this USB A-male to A-male cable.

The internal wiring of this cable is crossed over, which ensures the correct connections will be achieved in
both computer-to-computer and computer-to-device scenarios.

The pinout of this "strict" cable meets the USB 3.0 specification exactly.

The USB 3.0 specification states that pin 1 (VBUS), 2 (D-), and 3 (D+) are not connected. This means that
the cable is NOT backwards compatible with USB 2.0 devices.

Please note that computer-to-computer connections are for debugging and testing only, and current
operating systems DO NOT support file transfer or networking over USB.

 

You can use either USB2 or USB 3 to connect the PCS, but make sure the max length of the cable is less than 5 meter.

 

There is at long last a target disk mode options for PC's, and it is cross platform compatible with Mac's too, and they have a cross platform model for Android and Ipad/iPod/iPhone.

It also servers as a KVM switch too, minus the V for video.

Enjoy!!!

Quote from site:

Host Interface USB 2.0 - A-type Connector
Operating System Support Windows 8.1 / 8 / 7 / Vista / XP
Mac OS X 10.10 / 10.9 / 10.8 / 10.7 / 10.6
iPad: USB connection kit is required
Max Line Rate Up to 480 MBS

Anyone know if it is yet possible to use USB 3.0 to connect 2 PCs together?

I want to do exactly what the original poster wanted to do.

I want to connect a home built NAS to my computer, essentially making it a DAS so that I can exceed the 1Gbps Ethernet standard.

THE KEY that a lot of people are not realizing that the OP mentioned is to exceed 1Gbps which anything that is USB 2.0 based will NOT do. They are limited to 480Mbps and in practice actually perform at about 1/3rd the speed of Gbit Ethernet.

 

OK, ok, ok, I linked the wrong model. A quick scan of their site would show the USB 3.0 model:

http://www.j5create.com/our-products/wormhole-switches/juc500.html

Here are the specs, quoted from their site:

Features

* No installation CD is required, simply Plug-and-Play
* Multi-display is supported between two connected computers with different operating systems
* Drag & Drop to transfer your data between two computers
* Save or Copy data, photos, music, and videos from a memory card between the two computers
* USB 3.0 SuperSpeed File Sharing Between MAC and PC
* Conforms to USB 1.1 for Keyboard/Mouse functions
* Conforms to High-speed USB 2.0 (480Mb/S) transfer rate
* Conforms to Super-Speed USB 3.0 (5Gb/S) transfer rate

And like I already said, you can hook a MAC up to a PC, vice-versa.

For those that CANNOT read a website(/cough GIVMEDEW), let me recap their model lineup:
JUC100 - USB2, Windows Only
JUC400 - USB2, Windows & MAC
JUC500 - USB3, Windows&MAC
JUC700 - USB3, Windows&MAC + Touchscreen + Phones
