Richard,
Is there a reason you don't use point to point RJ45 ethernet?
YEPP ;/
If a PC has USB it almost always has RJ45 ethernet.
As you say "*almost*"
If neither side has MDIX then RJ45
crossover cables are available to complete the connection. Why do you have
an affinity for USB cable solutions?
I summary my absolute required elements include all below:
existence
known to work
conveniently physicallt available
I'll admit there also are some preferences:
scratch an itch that has existed since days of USB 1.0
explore an un-explored realm
And winner is USB "null modem" cable ;}

I did a DuckDuckGo search for "USB-net interface" {with/without quotes}.
Found several interesting links, but not sure if any are what you are
speaking of. A link to specific device(s) you refer to?
so it's effectively an ethernet cable.
I purposely used the term "null modem". I date from an era/industry
where
where 20 mA current loop was preferred over RS-232C for its noise
immunity.
Since USB 1.0 I've considered "universal" of USB an unfortunate choice of
adjectives. The intrinsic implementation of hardware to forever be
either a
*MASTER* or slave is annoying.
Most modern distributions just work. The one you link is
a USB-to-serial-to USB. That is not ideal for transferring files.
Depends on your metric.
If you
are unclear on what the "link" cable supports, you can always just buy
two
usb-ethernet adapters and an ethernet cable to go in the middle.
That explicitly is to be avoided as an unnecessary complication.
Maybe more adpatable than a "link cable".
I want a USB cable that is as functional (my metric) as a RS-232 cable of
decades past. The only observable difference would be max available
speed.

It would seem an appropriate solution for some file sharing between
two
Linux machines which have only USB 2.0 in common.
Has anyone used this or a similar product.
TIA
