OT: USB Computer-to-Computer

Use a data-com program that does binary transfers over the serial port. Error checking and protocols can be dispensed with when using a short hardwired connection.

I used to be in the 'business' - Lync Data Communications Program marketed by Norton Lambert. Sorry, but its DOS.

You're really trying to torture someone, aren't you? At .115 Mb/S it will take all day to d/l a bunch of high res pictures. .115Mb is not even .01 MB, or 10kB/S. For a 3 megapixel or 1 Megabyte .JPG picture, that's over a hundred seconds or more than a minute and a half per pic. Gimme a stinkin' break!

Use sneakernet. Either save them to a Zip drive, which can be connected to a parallel port, or else burn 'em to a CD-ROM. This is the best way, because you have a backup copy. If you must connect them together, use a special USB cable that's made for connecting two PCs together. But USB is usually 1.1 and that's no faster than your parallel port. You can make or buy a parallel port cable and use the built-in progtram.

Yeah, really. Reminds me of my 92 yr old neighbor. She says, "I don't know how I've lived this long. Everyone else I knew has died." :-O

External USB->Ethernet adapter. Around $20-$25.

USB Thumb drive or flash card and reader. If you don't have one, go to any public place and holler out your need. You'll find a hundred of 'em within shouting distance. mike

Something like that was included free with later versions of DOS. Thankfully I can't remember the name of it, but it used the "standard laplink(Tm) cable. PAINFULLY slow for even 20 or 30M let alone something that would fill up a disk drive.

Yeah, probably a better idea than using the Zip drive that I suggested, now that 128MB USB flash drives are only $20 and a half Gig is less than $50. Some older PCs have to have a drive installed.

That's the first time I've seen someone obfuscate a URL. I can see doing it to the email address, but why a URL? Especially Geosh!tties.

Exactly. And if the 5V line is connected thru, then if one PC isn't turned on, the 5V power from the other PC will try to go thru to it, and probably burn something out. If you're lucky, there's a fuse for that port on the MoBo that will blow, but still it's "not a user serviceable part".

Reminds me of the time I tried connecting the pigtail of the 2 USB port jacks on the adapter slot to the connectors on the MoBo. For some reason they had one of the connectors oriented on the board like the other connectors, with pin 1 towards the rear. And I assumed they were both that way. Well, the other was bass ackwards, with pin 1 towards the front! And when I turned it on, the jacket on the pigtail started to melt, and of course the smell of burned plastic. I killed the power quickly, and disconnected the jumper and didn't look into the problem for months. I thought that the bozos at the adapter mfg co goofed with the pigtail wiring. But then later I decided to try to resolve the problem, and I downloaded the manual with the MoBo layout from the Shuttle website. And then I found out they arranged the two side-by-side connectors thus. ( 1 = pin 1 )

What a dirty, rotten trick to pull on users!

I don't understand it either. The symptom is that when someone replies to my return address, the mail gets returned with an error message stating that AOL rejected it.???? Problem is worse with tripod links. This seems to fix it.

has the USB cable and the software to do this. They even have a free trial version that will work with RS232 or Parallel or USB and will transfer up to 10 megabytes or 10 files per run, then you re-run it. The full version has no such limitation.

And, if the contents of the old machine are critical, and thus you don't want to risk installing new hardware or software, there is even a floppy boot disk server version of this that can transfer the files without needing extra space or risk of installation.

I realize that some will say this may be too slow for them. There is nothing I can say to them. I just started the transfer and peeked over at it now and then to see that it was still humming along until it finished.

I don't get paid to say this, it just saved my bacon once. (the size of the drive on the old system was a drop in the bucket of the size of the drive on the new system)

This one is a real USB data transfer cable. It has a lump in the middle with the necessary circuitry to transfer data between two PCs.

But beware - at other places I have seen a straight USB-A to USB-A cable. I have no idea what people use these for as you can't just plug two computers together and expect anything to work.

Jim, you can buy USB to USB data cables that look like a network connection but you may be better off with a USB-Ethernet adapter if you have a network, should need no drivers setting up on your machine.

It suddenly hit me this morning... indulge myself and buy a wireless network. Use it to fix my dad's laptop, then install it in mine ;-)

Any brand recommendations?

Jim, a really handy device to have around is an adapter to plug in a

2.5" drive into a 3.5"cable. It costs about $5, and it's saved my bacon a number of times. The fastest way to transfer the data is to take the laptop hard drive out and put it in the desktop. The time spent moving the drive will be more than made up by the speed of transfer. Just don't let Dad see the surgery.

No. Straight USB-A to USB-A cables (and USB-B to USB-B cables) are technically "illegal" according to the USB spec. See for yourself at the official website
