(disconnected)
The value reported by XHCI PORTSC, 0x000202a0, indicates:
BIT5-8 : 5) Link is in the RxDetect State
BIT9 : Port Power (PP) – RWS. Default = ‘1’
BIT17 : Connect Status Change (CSC)
It is clear that the XHCI controller has received a disconnect event
from the UPS.
Can you check the other OS'es where this supposedly does not happen,
if the UPS device attaches to the XHCI or EHCI controller?
Windows 10 Device Manager shows it under "Intel(R) USB 3.1 eXtensible
Host Controller". This laptop (with Windows 10) has only USB-C ports...
I've captured sessions on Windows with "Device Monitoring Studio" and
WireShark (it was two sessions, not one) and uploaded them at
http://lev.serebryakov.spb.ru/_sklad/ups/
ups-windows-dms.dump - dump from "Device Monitoring Studio"
ups-windows-dms.log - log from "Device Monitoring Studio"
ups-windows-wireshark.pcapng - dump from WireShark
ups-windows-wireshark.txt - dissection export from WireShark.
My FreeBSD laptop (Lenovo T540p) has both USB 2.0 an USB 3.0 ports, and
UPS flickers in both.
Did you start any driver for the UPS?
On FreeBSD — I'm not (`nut` supports this UPS, but it detects device
slower than UPS stay connected).
Windows 10, Windows installs something generic and not very useful (it
shows battery level as 0%), but "provided" software (very crude one)
works and shows plausible information.
Windows 10 shows it as "HID UPS Battery" in device manager.
Hi,
Could you do:
usbdump -i usbusX -f Y -s 65536 -vvv
Where X.Y are the numbers after ugen for this device. Are you certain
that NUT only execute exactly the same commands like the windows tool
for this UPS? Does apcupsd work for this device too? I've never used NUT
myself.
