https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D269729 Bug ID: 269729 Summary: sysutils/nut USB permissions issue Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: cy@FreeBSD.org Reporter: dennypage@me.com Assignee: cy@FreeBSD.org Flags: maintainer-feedback?(cy@FreeBSD.org) I maintain the NUT package for pfSense and have run into an issue with USB permissions for some UPS models.=20 NB: My testing is against nut-2.8.0_13, but I haven't seen anything suggest= ing that the issue is resolved in later port revisions. The permission problem arrises from the fact that the kernel attaches a dri= ver to the device during initialization, and this subsequently prevents the dev= ice from being opened by usbhid-ups. The error reported is "Can't claim USB dev= ice" The following demonstrates the specifics: ----- [23.01-RELEASE][root@fw]/root: usbconfig -d ugen0.2 show_ifdrv ugen0.2: <American Power Conversion Smart-UPS1000 FW:UPS 16.0 / ID1047> at usbus0, cfg=3D0 md=3DHOST spd=3DFULL (12Mbps) pwr=3DON (10mA) ugen0.2.0: uhid0: <American Power Conversion Smart-UPS1000 FW:UPS 16.0 / ID1047, class 0/0, rev 2.00/0.01, addr 4> [23.01-RELEASE][root@fw]/root: /usr/local/libexec/nut/usbhid-ups -a ups Network UPS Tools - Generic HID driver 0.47 (2.8.0) USB communication driver (libusb 1.0) 0.43 interrupt pipe disabled (add 'pollonly' flag to 'ups.conf' to get rid of th= is message) Can't claim USB device [051d:0003]@0/0: Other error [23.01-RELEASE][root@fw]/root: usbconfig -d ugen0.2 detach_kernel_driver [23.01-RELEASE][root@fw]/root: usbconfig -d ugen0.2 show_ifdrv ugen0.2: <American Power Conversion Smart-UPS1000 FW:UPS 16.0 / ID1047> at usbus0, cfg=3D0 md=3DHOST spd=3DFULL (12Mbps) pwr=3DON (10mA) [23.01-RELEASE][root@fw]/root: /usr/local/libexec/nut/usbhid-ups -a ups Network UPS Tools - Generic HID driver 0.47 (2.8.0) USB communication driver (libusb 1.0) 0.43 interrupt pipe disabled (add 'pollonly' flag to 'ups.conf' to get rid of th= is message) Using subdriver: APC HID 0.98 [23.01-RELEASE][root@fw]/root:=20 ----- As you would expect, if the "-u root" option is added to usbhid-ups then it will succeed even if the kernel driver is currently attached. I note that this permission issue is also present in the truss outputs in b= ug #267144 --=20 You are receiving this mail because: You are the assignee for the bug.=
