Hi,
I Connected my 2 PC's with ISB 2.0 Data Link cable (ALI M5632 Chip)
and it seemed to working fast & Fine.

After a short time i've noticed that "big" files,
like the one I tried o transfer 5.5GB was not fully transfered.
the file recived was 1.6GB size.

has anyone any idea what is wrong ??
I have WindowsXP SP2 platforms & NTFS File System
on both PC's

any help would be a great help.

maybe you didn't allow it sufficient time to transfer.

Hello,

You may wish to disconnect any unneeded USB peripherals such as printers, scanners and joysticks in case having them on the USB bus interferes with the file transfer process.

Hi I have a same problem! With same cable! But maybe it is just chance occurrence. Lets see

I can't transfer files without throuble. Transfer will be aborted with different messages like "Connection Timeout...", "...Locked..." or files comes corrupt. And NOT 5gb big. I can't transfer 100mb files or even smaller!!!

I was not sure about blame of this cable, because i still use for the usb2.0 transferring between my laptop and pc (they both have usb 1.1, NTFS filesystem) PCMCIA USB2 cardbus and USB PCI card. They have ali and via chipsets and can be easy blame too.

Today i have try Superlink Network connection, and now it is a bit better: connection is longer fit and i get files complett transferred. Have you try it??
Also now it notify me immediately if an error accours (like ~Network destination name is not exist) and don't send data longer, like before, and at that time i have to must check crc finally anytime.

I ask me, should i buy the new cable?... Please let me know, do you have find solution?

I'd suggest that you use a backup solution that keeps a log of the transfers - that way you can see what files made it and what files didn't. I use SyncBack for this and others suggest Cobian Backup (both have free versions).

I'd also suggest checking to see if your motherboard/chipset drivers are up to date, and that the cables are fully inserted into the USB ports without any tension to pull the plugs to the side.

Checking the cable is the easiest thing to do - but you'll have to buy or borrow another one to see. Maybe you can purchase one from a shop that has a return policy for them?

Thanks for your suggesting!
I have already thinking about such "software" solution. For one file transferring with verification from windows context menu (backup to...) i have found this nice tool: CopyTo Synchronizer. With VirtualNetwork Superlink it goes fairly. I wish no error occurs while transferring even though.

With solutions like cable stability, length, and drivers it was many to examine...

It is there an "USB Monitor" program, but its some kind advanced and i can't get any goodness from it.

Hello,

If both computers have Ethernet adapters in them, have you considered connecting them with a cross-over cable and transferring files that way?

Hello,

One important thing to keep in mind is reports of speeds such as 480Mbit/sec or 100Mbit/sec are just counting the number of binary digits (those "1 and 0" bits) sent over an interface. They don't take into account the overhead required to "frame" the data being transmitted, e.g., the sequence of "control" bits which must be used to signal that a block of data, such as a byte, have been sent, nor does it take into account the overhead of "serializing" or converting the data into a signal which can be transferred across the USB bus (which may, in turn, affect processor utilization), or possible delays introduced by having the computer's USB adapter respond to requests from other devices connected to it, such as image scanners, keyboards, mouses and so forth.

This overhead is the reason why FireWire (IEEE-1394) interfaces transfer data more rapidly than USB 2.0 ones, despite the fact that USB transfers 480Mbit/sec to FireWire's 400Mbit/sec.

But, to get back to the problem at hand, you are unable to complete the transfer of files from one computer to another using USB 2.0, so in this case, the USB interface is less useful than a slower but more reliable connection, irrespective of whatever the theoretical speed is of the connection--a very fast connection is not as useful as a slower one if the very fast connection doesn't transmit all of the data between the endpoints.

Hi, boys!
My english is bad, but:
The good idea is: fast file transfer without Files and Printer Sharing Protocol & Shared Folders etc.
I have a Ali Super Link Hi-Speed USB Link Cable version USL201A-0 (made in China, or Rossia?). Is realy much faster from my LAN 100.
The software from my original CD is version 120d - problem with files bigger 2Gb.

1. Downoad new software from http://www.usbfirewire.com/manualsdrivers/rr-usb-usb2dbali.zip (http://www.usbfirewire.com/Parts/rr-usb-usb2db.html).
2. Do not install!!!
3. Copy from ZIP-file the "NT" folder & create a shortcut to desktop "Shortcut to SuperLink.exe".
4. Enjoi
