Check me on this ...<br class="gmail_msg">
<br class="gmail_msg">
Such means USB length is essentially infinite? IIRC, USB max. is 30',<br class="gmail_msg">
unless (powered) signal repeated - such as by these, daisy chained, even?<br class="gmail_msg">
<br class="gmail_msg">
Still limited to the max. bandwidth when it finally enters the computer,<br class="gmail_msg">
but this issue diminishes with USB 3, especially as hubs going outwards<br class="gmail_msg">
are also USB 3. i.e. If really far away, first hub or more could be USB<br class="gmail_msg">
2, as long as accumulation of such USB 2 hubs into the first USB 3 hub<br class="gmail_msg">
doesn't exceed USB 3 bandwidth.<br class="gmail_msg">
<br class="gmail_msg">
[This matters as I have zoneminder set up, with USB cameras - far<br class="gmail_msg">
cheaper / perhaps more effective, than IP cameras). USB length becomes<br class="gmail_msg">
an issue. {Even a 486 handled 5 such cameras at 320 pixels, greyscale.}<br class="gmail_msg">
Was fostering a feral cat at the time, and needed to see when he came<br class="gmail_msg">
out from under the sofa so he could be socialized. Limited camera field<br class="gmail_msg">
of view is annoying!]<br class="gmail_msg">
<br class="gmail_msg">
And by going in to different (non-shared) ports into the computer, one<br class="gmail_msg">
could presumably have a star of multiple chains of USB devices in all<br class="gmail_msg">
direction and far longer than the 30' USB spec. As long as there's a<br class="gmail_msg">
wall socket to power the hubs along the way. Unless I'm misunderstanding<br class="gmail_msg">
something?<br class="gmail_msg">
