[K2] USB version for USB to serial adapter

I want to connect my Windows 10 tablet to my K2. I have the KIO2 module
installed and I have built the K2 serial cable. I have read the relevant
material on the Elecraft website about avoiding the Prolific chipset. The
USB port on my tablet is 3.0. My question is this - can I use any version
of USB (1.1, 2.0, 3.0) to serial adapter to connect the tablet to the K2
cable or is one better than the others?

Thanks,
Mike

There were many counterfeit chips so the patent holders put code in
their drivers to disable the counterfeits. The USB version (1, 2 or 3)
does not matter. You want to get a genuine converter. Best way to
guarantee that is to buy your converter cable from a reputable source.
Elecraft sells one. So does MFJ. I am sure there are others. Just
don't get some cheap knock-off from the Internet.

Mike,

One of the potential problems is that the K2 works at 4800 baud, which
by current standards is slow.

The problem is that some USB to serial adapters do not like to run at
that slow speed. I have tested the Elecraft KUSB with my K2, and I also
can state the my 4 port Edgeport USB to serial converter works well.
I have also used a Keyspan adapter.

If you can arrange a "return if it does not work" arrangement with the
place where you buy it, that would be beneficial.
You can use a USB 1.1 or 2.0 or 3.0 adapter.

My experience with "mix and match" USB ports and devices caused a bit of
problems. My external backup drive is in a USB-3 housing, and I
connected it to one of my Dell tower's USB-3 port with a USB-3-rated
cable. I experienced quite a number of failures to recognize the drive
at backup time. After replacing both the drive disk and housing, the
results were the same. When I moved the cable to one of the computer's
USB-2 port, the problem went away.

The upshot of all this is, to paraphrase an otherwise forgettable MIT
professor of many decades ago "this USB not the same as that USB - I
only did that to con-fuse you".

I'll let Don and the rest of the experts here give more accurate answers.

I purchased a serial to USB adapter from Amazon that had the FTDI
chipset, and have had no problems with CAT control to the rig. I've
added a link to Amazon for that adapter, its only $12 but it works well.
