[Nut-upsuser] raspberry pi and tripplite_usb

[grumpy at mailfence.com]

i have a OMNIVS1500XL
i have used nut for several years on a full sized pc with no problems
i am trying to get nut working with this ups on a raspberry pi
i tried with a pi 3b running raspbian stretch
i tried with a pi 3b running raspbian buster
i tried plugging the usb cable straight into the pi
i tried using a powered usb hub
i tried rebuilding nut from the source package
all caused the pi to crash after 1/2 days
the crash report always begins with
"Unable to handle kernel paging request at virtual address 30343153"
any suggestions
