A question about daisychaining USB 2 cables

[Pask]

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 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 printer cable. 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?

No. 16ft limit. It may work at 22ft. But it also may get errors.

That will work fine. 16 ft is the limit for a passive extension, or any combo of daisychained passive cables up to 16ft. If you're using a 16 ft active cable with a 6 ft printer cable you'll be fine. Actually the limit for high speed 2.0 with active daisychained cables is 30m (just under 100 ft) That's achieved by connecting 5 x 5m (16 ft) active cables or hubs, with an additional device cable not exceeding 5m - to total 30m. It does depend on the quality of cable though - it needs to conform to the spec of 480Mbps transfer speed and proved a min of 250mA - for high speed 2.0. Not all cables are created equal - generally you get what you pay for.

What you are trying to accomplish is exactly this:

"The extensions cables built in signal booster ensures reliable data transfer for the combined length of the extension cable, AND your device cable"
In theory, up to a 16 ft device cable after an active extension or hub, but in practice it almost certainly wouldn't work reliably. In your case with only a 6 ft printer cable you'll be fine.

Again though, only if the cable is decent quality.

Thanks, very helpful
