I've been playing with an APC Back-UPS ES 450 and experiencing a strange problem. If I plug the UPS into the box after it has completely booted, it is recognized by the kernel and mapped to a ugen device: kernel: ugen0: <APC Back-UPS ES 450 FW:844.K1d.D USB FW:K1d, class 0/0, rev 1.10/1.06, addr 2> on uhub0 However, if I have the device plugged in when the box boots, a ugen device is not created and the only error I see in dmesg is: uhub0: device problem (TIMEOUT), disabling port 2 Would this be related to a USB problem in FreeBSD, or is it the fault of the UPS? Are there some additional tools I can use to debug this further? cva # uname -a FreeBSD blah.aloof.org 7.0-RELEASE FreeBSD 7.0-RELEASE #0: Sun Feb 24 10:35:36 UTC 2008 root@driscoll.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64 # dmesg | egrep '^(usb|uhub)' usb0: OHCI version 1.0, legacy support usb0: SMM does not respond, resetting usb0: <OHCI (generic) USB controller> on ohci0 usb0: USB revision 1.0 uhub0: <ATI OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0 uhub0: 2 ports with 2 removable, self powered usb1: OHCI version 1.0, legacy support usb1: SMM does not respond, resetting usb1: <OHCI (generic) USB controller> on ohci1 usb1: USB revision 1.0 uhub1: <ATI OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb1 uhub1: 2 ports with 2 removable, self powered usb2: OHCI version 1.0, legacy support usb2: SMM does not respond, resetting usb2: <OHCI (generic) USB controller> on ohci2 usb2: USB revision 1.0 uhub2: <ATI OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb2 uhub2: 2 ports with 2 removable, self powered usb3: OHCI version 1.0, legacy support usb3: SMM does not respond, resetting usb3: <OHCI (generic) USB controller> on ohci3 usb3: USB revision 1.0 uhub3: <ATI OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb3 uhub3: 2 ports with 2 removable, self powered usb4: OHCI version 1.0, legacy support usb4: SMM does not respond, resetting usb4: <OHCI (generic) USB controller> on ohci4 usb4: USB revision 1.0 uhub4: <ATI OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb4 uhub4: 2 ports with 2 removable, self powered usb5: EHCI version 1.0 usb5: companion controllers, 2 ports each: usb0 usb1 usb2 usb3 usb4 usb5: <EHCI (generic) USB 2.0 controller> on ehci0 usb5: USB revision 2.0 uhub5: <ATI EHCI root hub, class 9/0, rev 2.00/1.00, addr 1> on usb5 uhub5: 10 ports with 10 removable, self powered uhub0: device problem (TIMEOUT), disabling port 2
