Hi All; I noticed last night that my app_rpt box with 3 fobs (the LEDs on which usually flash away), all had lights out yesterday. Interestingly, when I do an 'lsusb' - I don't see them: [root@ve3rsd-ast ~]# lsusb Bus 002 Device 001: ID 0000:0000 Bus 004 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 [root@ve3rsd-ast ~]# The USB controllers seem to be there: [root@ve3rsd-ast ~]# lspci | grep USB 00:1d.0 USB controller: Intel Corporation NM10/ICH7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB controller: Intel Corporation NM10/ICH7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB controller: Intel Corporation NM10/ICH7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB controller: Intel Corporation NM10/ICH7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB controller: Intel Corporation NM10/ICH7 Family USB2 EHCI Controller (rev 01) dmesg lists them too...

Environment specifics: [root@ve3rsd-ast ~]# cat /etc/*release* cat: /etc/lsb-release.d: Is a directory CentOS release 5.9 (Final) [root@ve3rsd-ast ~]# [root@ve3rsd-ast ~]# uname -r 2.6.18-308.8.2.el5 Anyone have any ideas? Thx, Ramesh.
