>Using Synaptic I removed apcupsd and the associated gui monitor, shut down the machine, removed the usb cable connecting the machine to the battery backup, and rebooted. The footpedal program started without my needing to correct its permissions, and it works with transcribe. I've gone for many years without an automated shut down on power fail so I'm not too concerned about it. I discovered the program udevadm and tried sudo udevadm info --export-db > udevdb.txt That gave me TMI, but I was able to locate information about the usb two devices I had connected, the VEC foot pedal and the APC foot switch. But I wasn't able to interpret the rest of the information sufficiently to see where the difficulty lay. If anyone sees something useful below that could help me figure out how to get both devices working at the same time I'd appreciate it. Here's what I extracted from udevdb.txt: P: /devices/pci0000:00/0000:00:1d.3/usb5/5-1 N: bus/usb/005/002 S: char/189:513 E: UDEV_LOG=3 E: DEVPATH=/devices/pci0000:00/0000:00:1d.3/usb5/5-1 E: MAJOR=189 E: MINOR=513 E: DEVNAME=/dev/bus/usb/005/002 E: DEVTYPE=usb_device E: DRIVER=usb E: PRODUCT=5f3/ff/120 E: TYPE=0/0/0 E: BUSNUM=005 E: DEVNUM=002 E: SUBSYSTEM=usb E: ID_VENDOR=VEC E: ID_VENDOR_ENC=VEC\x20 E: ID_VENDOR_ID=05f3 E: ID_MODEL=VEC_USB_Footpedal E: ID_MODEL_ENC=VEC\x20USB\x20Footpedal E: ID_MODEL_ID=00ff E: ID_REVISION=0120 E: ID_SERIAL=VEC_VEC_USB_Footpedal E: ID_BUS=usb E: ID_USB_INTERFACES=:030000: E: DEVLINKS=/dev/char/189:513 P: /devices/pci0000:00/0000:00:1d.2/usb4/4-1 N: bus/usb/004/002 S: char/189:385 E: UDEV_LOG=3 E: DEVPATH=/devices/pci0000:00/0000:00:1d.2/usb4/4-1 E: MAJOR=189 E: MINOR=385 E: DEVNAME=/dev/bus/usb/004/002 E: DEVTYPE=usb_device E: DRIVER=usb E: PRODUCT=51d/2/106 E: TYPE=0/0/0 E: BUSNUM=004 E: DEVNUM=002 E: SUBSYSTEM=usb E: ID_VENDOR=APC E: ID_VENDOR_ENC=APC E: ID_VENDOR_ID=051d E: ID_MODEL=Back-UPS_ES_550_FW:843.K2_.D_USB_FW:K2 E: ID_MODEL_ENC=Back-UPS\x20ES\x20550\x20FW:843.K2\x20.D\x20USB\x20FW:K2\x20 E: ID_MODEL_ID=0002 E: ID_REVISION=0106 E: ID_SERIAL=APC_Back-UPS_ES_550_FW:843.K2_.D_USB_FW:K2_4B1126P01814 E: ID_SERIAL_SHORT=4B1126P01814 E: ID_BUS=usb E: ID_USB_INTERFACES=:030000: E: DEVLINKS=/dev/char/189:385 P: /devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/0003:051D:0002.0001 E: UDEV_LOG=3 E: DEVPATH=/devices/pci0000:00/0000:00:1d.2/usb4/4-1/4-1:1.0/0003:051D:0002.0001 E: DRIVER=generic-usb E: HID_ID=0003:0000051D:00000002 E: HID_NAME=APC Back-UPS ES 550 FW:843.K2 .D USB FW:K2 E: HID_PHYS=usb-0000:00:1d.2-1/input0 E: HID_UNIQ=4B1126P01814 E: MODALIAS=hid:b0003v0000051Dp00000002 E: SUBSYSTEM=hid Thanks. -- Regards, Dick Steffens _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
