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.

TIA

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.)

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.

For help with BIOS settings, try the old Rojakpot pages. They're

Sometimes, the BIOS companies product documents to help with
BIOS settings. There isn't really that much extra detail here
for "Legacy USB Support".

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.
