This is correct behavior. This hub is actually 2 4-port hubs which are daisy chained internally together - second hub is wired to port 3 of master hub.
I meant you should not touch state for 3-1.5.3, because it will lead to unexpected behavior. Turning on/off any other ports should work.
@mvp Thanks for the quick reply - that makes a lot of sense.
Any suggestions how to cycle power of port 3 of the 3-1.5
and not 3-1.5.3
?
Actually, you don't want to ever touch port 3 of 3-1.5
- this is daisy chain port to second hub. Turning it off should make second hub completely disconnected, which depending on hub circuitry may give all kinds of surprises.
To operate on port 3 of slave hub3-1.5.3
, simply specify hub location using -l
option, something like this:
uhubctl -l 3-1.5.3 -p 3 -a 2
This would reset port 3 of second hub in chain. For location parameter, you need to use hub id that uhubctl prints - it is basically the same id that you would see in Linux kernel dmesg and other logs when hub is first enumerated.
Thanks I will try it out tomorrow.
Would you know of a hub with 5 or more ports that don't daisy chain?
Thanks again!
D-Link DUB-H7 is true 7 port hub with power indicators per each port that works really well. But you need to find old silver edition (perhaps on eBay), as new black edition doesn't support PPPS.
Thanks for confirming!
Hi very nice software.
I purchased the Amazon basics 7 port hub as recommended and when I run
./uhubctl
as root the Amazon hub is displayed twice.If I try to control ports by turning them off, it works. However when I try to turn them back on or cycle the power, the software hangs after sending the power off command. I am suspecting the problem is the fact that the hub is being detected twice.
I am running Debian Jesse 8.7 (3.16 kernel)
Any ideas?
Thanks!
