Hello all!

<pr0cess0r>
i have a hard time finding info about properly implementing usb on the PB
<pr0cess0r>
i have a board with one usb port wired it work but what about adding a usb hub and proper esd over current protection?
<zmatt>
I mean, simplest way would be to just hook up an off-the-shelf hub
<zmatt>
(preferably a separately powered hub (rather than a bus-powered hub) since those are required by the usb spec to have overcurrent protection)
<pr0cess0r>
look like it need to be powered
<pr0cess0r>
do you know if for example a powered hub that i dont power will allow more amp to be draw from the usb pour ?
<pr0cess0r>
vs opne that dont have a power input
<pr0cess0r>
that would be a solution!
<zmatt>
I have no idea what you're trying to ask
<pr0cess0r>
you said that bus powered hub must have current limit
<zmatt>
no
<zmatt>
I said the exact opposite
<pr0cess0r>
oups i re read it sorry
<zmatt>
a bus-powered hub is allowed to simply rely on the protection that the host port is supposed to have
<pr0cess0r>
ok i see
<pr0cess0r>
so its safer to use on a bare usb port like i have now
<zmatt>
(which will be absent if you wired it up to the pocketbeagle without any circuit)
<zmatt>
no
<zmatt>
you have no protection right now
<zmatt>
well, depends on how you wired it up I guess
<pr0cess0r>
i mean une my not protected port with a powred usb hub
<zmatt>
if you connect a powered usb hub to the pocketbeagle then it should take care of things
<pr0cess0r>
it have a 500mA ptc fuse but no other protection
<zmatt>
do be careful, some cheapass powered usb hubs backfeed power to the host power, which is absolutely forbidden by the usb standard can can potentially damage the host
<zmatt>
*and can
<pr0cess0r>
that why i try to get information and do better usb design on my board
<zmatt>
I mean, it's possible of course but not simple
<pr0cess0r>
but wonder if possible to do something similar with usb hub on board
<zmatt>
sure, but a well-behaved usb hub is not simple... also keep in mind that usb 2 signals are quite high speed and require careful PCB design
<zmatt>
unfortunately I need to go, afk

Hello...um, Does HexChat support the LiberaChat stuff?
<vagrantc>
you might have to manually add configuration for it rather than selecting from a preconfigured network, but no reason it wouldn't support it

welcome back
<set_>
It is me!

Now, time to lock it like Becky on Dancing w/ the stars!
<set_>
YOu know? Pop, lock and drop it?
<vagrantc>
can't say i do
<set_>
Forget it.
<set_>
Oh.
<set_>
WEll, you should try it one day!
<vagrantc>
how's your flying beagle going?
<set_>
You just repeat those words over and over. Then, some spasms and a nice whoot!
<set_>
vagrantc : Did you try it yet?
<set_>
Fine. I will try it by myself. Argh.
