Hi Experts,

searched many places and downloaded two different drivers but they don't

Device
Mgr always shows a big yellow Q mark at USB Device for it. If I
uninstall
the software, the question mark goes away but there is no trace of an
installation I did leave the cable unplugged until the software was
loaded
but it didn't help.

The cable I have has no brand but the plugs are standard and do hook the
two
boxes together. The enlarged part on the middle of the cable reads "USB
Network Cable."

Anyone know where I can find a driver for the cable and Win2K?

They call it PCLinq here. More than one company made a chip for it.
I think one company had to stop making it, due to a patent.

I'd probably start with a copy of UVCView and get the
vendor and product numbers. And then maybe you can figure out
who makes the chip inside it. As far as I know, there
is no standard USB device class for those things. So
you'd likely want to get the software from the company
that made the cable. The label printed on the cable
may be of more value, than the electronic identification.

Once you've got some identifying information, it
may be easier to track down a driver. If the
only version of software, is on the included CD,
then you may have a tougher time finding it.

Thanks Paul for the very helpful reply. I'll investigate your suggestions.

Just after I posted I thought of checking the BIOSs - my most recent
computer had both legacy and USB2 already turned on. The other box is
lder - the legacy was turned off and the USB2 was not mentioned. I turned
on the legacy and I'm guessing that this is the max speed I'll be able to
get with those two boxes - no problems though. I don't have very much to
transfer. I also have several CDs with loads of USB progs.

I'll be back soon. Thanks again.

Hi Experts,

I have 2 Win2K boxes and want to connect them via my USB2 cable. I have
searched many places and downloaded two different drivers but they don't

Mgr always shows a big yellow Q mark at USB Device for it. If I uninstall
the software, the question mark goes away but there is no trace of an
installation I did leave the cable unplugged until the software was loaded
but it didn't help.

The cable I have has no brand but the plugs are standard and do hook the two

Many thanks Paul. I did find the items you mentioned but failed to make the
connection. I suspect the problem is the older box. The vendor and product
IDs were the same as the ones you quoted.

I found that the bios in the older box had Legend only and the newer one had
both Legend and USB2. Both bioss are turned on for the USB and the older box
always shows a yellow exclamation mark. The older box does have 2 USB
connections - is it necessary to have a plugin card to get the USB to work
on these data transfer cables?

The PCLinq software sets up very easily - now all I need is the connection.

Do other USB devices work on that machine ?

I would expect it to work, even if one end is at USB 1.1 rate
and the other end is USB 2.0 rate. With the limited number of
buffers, it should just stop when the buffers are full, until
the other side drains the buffers. (I didn't know these had a
processor inside - I thought ping-pong chips were dumb and mechanical.
I don't see the need for a processor in there. Maybe it is a
performance optimization.)

http://www.prolific.com.tw/eng/Products.asp?ID=18

I would try to connect both PCs to the same power strip, so
there aren't any grounding problems. If you can use UVCView
on each PC, and see the idVendor and idProduct, that tells
me the lowest level (PHY) communications must be working.

After that, it would be a driver issue.

On the affected machine, is the PL-2501 causing a networking
item to appear in Device Manager ? Maybe it is there, but has
become bound to the wrong standard (NDIS).

There are ways to delete USB items in Device Manager, such that
they get redetected, but in this case, I don't see how that is
going to help. There is an example here, which relies on
Microsoft DEVCON, to interact with the Device Manager. Doing
stuff like this can be risky.

Thanks Paul. I had a temporary fix using an external drive. I have seen PCI
cards for $10 that
can be used in PCs to get USB2. As I understand it, I would need just one
for my older computer. I may yet go that route.
