I am wondering if the pegasus power box advance (PPBA ) driver can incorporate USB hub per-port power control.
From the readme on the git repo
github.com/mvp/uhubctl , it looks like Windows users may be out of luck.
If so, would that preclude developing the driver further so that hub control is available for linux users ? I received
this info from Evans as Pegasus Astro:
the USB Hub supports ON/OFF for each port in software.
You can check more about that here:
github.com/mvp/uhubctl
Example
$ uhubctl
Current status for hub 20-14, vendor 2109:2813, 4 ports
Port 1: 0103 power enable connect [0403:6015 Pegasus Astro PPBA revA PPBA4ZNGNY]
Port 2: 0100 power
Port 3: 0100 power
Port 4: 0100 power
E.g I want to turn off port 2:
ubctl -p2 -a 0
Current status for hub 20-14, vendor 2109:2813, 4 ports
Port 2: 0000 off
Sent power off request
New status for hub 20-14, vendor 2109:2813, 4 ports
Port 2: 0000 off
Verification
$ uhubctl
Current status for hub 20-14, vendor 2109:2813, 4 ports
Port 1: 0103 power enable connect [0403:6015 Pegasus Astro PPBA revA PPBA4ZNGNY]
Port 2: 0000 off
Port 3: 0100 power
Port 4: 0100 power
