A question about daisychaining high speed USB 2.0 cables

Specs: Windows 7 64 bit Ultimate, i7 4790 \ 24 Gb's GSKILL 1600 DDR3
I want to run an extension from my computer to my printer. From what I'm reading, 16ft is the max recommended length for a non active high speed USB 2.0 extension. My plan is to buy a USB A male to A female active extension to use with a 6ft USB A male to B male passive printercable.

If I buy a 16 ft A to A USB active extension, will that work if I pair it with my 6 ft printer cable? So that'd be a total 22 ft with just the one repeater in the 16 ft length extension cable?

If I'm reading this correctly, you can daisychain up to 5 ACTIVE cables, and one passive up to a limit of 98ft. - so 82 active and one 16 passive. Is this correct?

So does the 16ft passive rule apply after each active extension? I mean at some point, no matter how many I daisychain (within the rule), I need to add my 6ft device cable.

I'm going form these two sources:

Is the printer networkable - as in it has an ethernet port; even wifi?

If so the a n easier and neater approach is to use lan over mains adapters; they work well.

Likewise there are adapters that allow usb via the same adapters.

Thanks trvlr

No, it's not networkable. It's a Samsung ML 1670 Monochrome laser printer. It connects via 2.0 high speed.

Can you answer my questions?

I'm inclined to say that the link XpUser... has posted immediately above answers it perfectly.

Well it doesn't answer the question. But thanks for trying.

From your article:

"You can, however, have a 6 foot cable and a 10 foot extension cable run for
a total of 16 feet making the power of USB very limited."

That doesn't apply in my case as I'm not trying to run 16ft of daisychained passive cable, as their example suggests.

The rest of the article is basically a re-iteration of the info from the 2 links in my op. (read it carefully)

I wasn't asking how long can you daisychain active cables.
I wasn't asking how long you can daisychain passive cables.
That info was covered in the links from my op.

My question was:

How long of a passive cable can you run after an active extension - daisychained or not

I wanted:

- 16ft active with repeater
- 6 ft passive

Looking into this further I found the exact answer:
Here's a summation:


"The extension cables built in signal booster ensures reliable data transfer for the combined length of the extension cable & your device cable"

Contacting them to clarify how long of a device cable:

If the active cable is of good quality and conforms to the High-Speed 480Mbps transfer rate with 250 mA per port, then theoretically you can add up to another 16ft of passive. (Theoretically, as in practice it rarely works up to that length after an active extension) It depends on the quality of the cable, and if the device is powered or not.

As it was explained to me, you can consider the end of the active cable (again, depending on quality) to be equivalent to the USB port on your computer.

In my case a 16ft active with a 6 ft passive printer cable is fine. It will work. The Passive portion is well below the 16 ft limit.
