For anyone else with a similar problem, I'm using the following devd rule to mitigate the issue (https://pastebin.com/raw/HmDur3Le): notify 100 { match "system" "USB"; match "subsystem" "INTERFACE"; match "type" "ATTACH"; match "vendor" "0x8087"; match "product" "0x07dc"; action "usbconfig -d $cdev power_off"; }; -- A: Because it fouls the order in which people normally read text.
