Don't remember the details, but the USB standard makes it physically impossible. There must be an active device in the middle of the cable. But don't take my word for it. Google "usb data transfer", etc. There are many on the market. |

How to make a USB 2.0 male x male data link
I would not advise USB to USB to transfer files. USB was not designed
for this. It is best done through the Ethernet port. There is a lot of information available about how to make a simple network between two computers for transfering files.

How to make a USB 2.0 male x male data link
Greetings "ctops.legal" et. al...
I couldn't agree with Jerry more! Even if configured for data transfer, USB is bandwidth limited for data of any substantial size. This is why our networks have notoriously been Ethernet based. The good thing about two computers that sport an Ethernet connection is you don't require a hub or a switch if you merely want to connect the two together. In front of me right now is a Belkin package for a CAT5e Crossover cable M/N: T3532G/A. Many other companies are making the same type of cable - probably for less money. Connect this cable between two computers having an Ethernet port and you'll typically have 10 or 100MBit/sec. connection and something less than that regarding the actual data transfer, considering the overhead, but it will usually be more than adequate for PC use. This is the way to establish data transfer at a better bandwidth with a protocol that was established for broadband reliable data transfer. Cheers, Mr. Mentor "Jerry G." wrote in message ...

This is the way to establish data transfer at a better bandwidth with a protocol that was established for broadband reliable data transfer. That's ok if both computers have an Ethernet port. If they don't, you have to install a network card, and configure them to the same networks. I have the software and active USB interface that installs and works in minutes, without changing the network configuration. It has a USB power processor that handles the data transfer, and handshaking. I have found a cheap one that works OK at a 'Dollar Tree' store, for a dollar, plus sales tax. I gave them to friends who wanted to borrow the expensive one, and they worked fine. http://www.usb.org/about/usb_nomenclature states that USB currently has a maximum data rate of 480 Mb/s, or almost five times that of 100 Mb/s Ethernet. Also, keep in mind that the actual data rates are about 20 MB/s and 40 MB/s These are both burst rates, because no PC can maintain those data rates on a continuous basis. Cheers, Mr. Mentor If you want to claim 'mentor' status, please give all the facts, not just your personal preferences. If someone wants to copy an entire hard drive, there are better ways, but to move some files between computers, either works OK. In the shop, I use a USB wireless internet to install software from the shop server, since there are places I haven't finished the network cabling. I have the advantage of being able to set up a computer anywhere there is enough space to work, without worrying about finding a free ethernet port. http://www.lyberty.com/tech/terms/usb.html has a comparison chart for the common interfaces, and versions. -- http://improve-usenet.org/index.html Use any search engine other than Google till they stop polluting USENET with porn and junk commercial SPAM If you have broadband, your ISP may have a NNTP news server included in your account: http://www.usenettools.net/ISP.htm |

I'll bet you get a few requests for trips to that store from here on... grin Michael |

I haven't seen any for about six months, but I think I might have one left, and hiding somewhere in the 1000+ spare cables in the shop. I have bought USb to ethernet adapters for under $10, though. -- http://improve-usenet.org/index.html Use any search engine other than Google till they stop polluting USENET with porn and junk commercial SPAM If you have broadband, your ISP may have a NNTP news server included in your account: http://www.usenettools.net/ISP.htm |

USB is a master/slave connection, and your intent is to connect two masters. It can be done, by a cable that supports a dual-port memory which is a slave to both the masters. And, some software. However, a peer-to-peer connection is far easier and can generalize to more than two computers. Firewire and Ethernet and variations on WiFi are the best choices here. Those little USB keychain flash drives are widely available, inexpensive and completely supported by modern OS software. Use them if it has to be a USB solution. |
