Hi Charles, I can see your thinking, but no, this isn't a VM, nor is the kernel I'm using a Hypervisor - it's a plain old machine:
root@barnbox:~# grep -i hyper /proc/cpuinfo root@barnbox:~# I updated the machine with apt-get (again) and I also updated the machine's BIOS. Prior to doing the updates I tried the lsusb command and it worked: root@barnbox:~# lsusb -vvv -d051d: Bus 001 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.06 iManufacturer 3 American Power Conversion iProduct 1 Back-UPS CS 350 FW:807.q10 .I USB FW:q10 iSerial 2 4B1419P32390 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 34 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xe0 Self Powered Remote Wakeup MaxPower 2mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.10 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1217 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0006 1x 6 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) root@barnbox:~# However, weirdly, since doing the update, usbhid-ups no longer segfaults - it still doesn't work, but it's interesting Annoyingly, I never ran the intermediate stages, so I don't know which change made the difference (I suppose it could be HP's firmware doing something funky, but I doubt it...): I believe this usbhid-ups command should match the UPS, but it appears to skip it: root@barnbox:~# /lib/nut/usbhid-ups -u nut -a apc -x bus=001 -x vendorid=051D -x productid=0002 -DDDD Network UPS Tools -
