F38 and NUT

Since upgrading to F37, I am having problems getting Nut to work properly. The errors I get from the journal are: Apr 26 17:01:42 seveneves.gregandeva.net nut-server[326151]: Can't connect to UPS [seveneves-ups] (usbhid-ups-seveneves-ups): No such file or directory Apr 26 17:01:42 seveneves.gregandeva.net upsd[326151]: Can't connect to UPS [seveneves-ups] (usbhid-ups-seveneves-ups): No such file or directory Apr 26 17:24:00 seveneves.gregandeva.net nut-monitor[326253]: Poll UPS [seveneves-ups@localhost] failed - Driver not connected All I could find on the net suggested that "Driver not connected" means I'm using the wrong driver, but this is the identical configuration (including the driver) that worked in F36. It's also a nearly identical configuration that is still working for an identical UPS unit monitored from a Raspberry Pi running Raspbian. Any Nut gurus here that could help me troubleshoot this, and has anyone else seen Nut quit working on F37 using a configuration that worked with F36? Here's what I have in my config files: nut.conf:MODE=netserver ups.conf:[seveneves-ups] ups.conf: driver = "usbhid-ups" ups.conf: port = "auto" ups.conf: vendorid = "0463" ups.conf: productid = "FFFF" ups.conf: product = "Ellipse PRO" ups.conf: serial = "P344L44127" ups.conf: vendor = "EATON" ups.conf: bus = "001" ups.conf: maxretry=3 upsd.conf:LISTEN 192.168.1.56 3493 upsd.conf:LISTEN 127.0.0.1 3493 upsmon.conf:MONITOR seveneves-ups@localhost 1 upsmon <redacted password> master upsmon.conf:MINSUPPLIES 1 upsmon.conf:SHUTDOWNCMD "/sbin/shutdown -h +0" upsmon.conf:POLLFREQ 5 upsmon.conf:POLLFREQALERT 5 upsmon.conf:HOSTSYNC 15 upsmon.conf:DEADTIME 15 upsmon.conf:POWERDOWNFLAG /etc/killpower upsmon.conf:RBWARNTIME 43200 upsmon.conf:NOCOMMWARNTIME 300 upsmon.conf:FINALDELAY 5 Thank you, --Greg
