ESXi-4.1: USB passthrough problem with APC Back-UPS CS 650

==== First of all:

1) I understand this

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=102134...

is the official list of supported USB devices; however I hope you'll have a suggestion even if my hardware is not on that list.

2) I understand there are alternatives to connecting an UPS directly to a VM (ie: network agent). But right now we don't have one of those UPSes and I'd

like to convert a physical machine to virtual with as few changes as possible.

==== HARDWARE:

ESXi-4.1 on Dell PE-T310.

VM (virtual hw v7): RHEL5.x (CentOS), latest kernel (2.6.18-194.17.4.el5)

USB device: APC Back-UPS CS 650 (051d:0002)

If used on the real hardware, the UPS is detected w/o any issue, I can start apcupsd and check its status.

==== PROBLEM:

If used attached to the VM (ESXi: add USB controller, then ADD USB device) the device is "partially" detected:

See lines marked with "<==== PROBLEM":

hub 2-0:1.0: USB hub found

usb 2-1: new full speed USB device using uhci_hcd and address 2

usb 2-1: configuration #1 chosen from 1 choice

drivers/usb/input/hid-core.c: usb_submit_urb(ctrl) failed <===== PROBLEM

drivers/usb/input/hid-core.c: timeout initializing reports <===== PROBLEM

hiddev96: USB HID v1.10 Device [American Power Conversion Back-UPS CS 650

FW:817.v4.I USB FW:v4] on usb-0000:02:02.0-1

Those 2 lines are not present when installing Linux on the PE-T310 directly.

When used in the VM I can start apcupsd but then either I get no output from apcaccess or I get empty values, like:

CABLE : USB Cable

MODEL : Back-UPS CS 650

UPSMODE : Stand Alone

STARTTIME: Tue Oct 26 20:20:05 CEST 2010

STATUS : ONLINE

LINEV : 000.0 Volts <==== PROBLEM

LOADPCT : 0.0 Percent Load Capacity <==== PROBLEM

BCHARGE : 100.0 Percent

TIMELEFT : 27.2 Minutes

MBATTCHG : 5 Percent

MINTIMEL : 3 Minutes

MAXTIME : 0 Seconds

OUTPUTV : 000.0 Volts <==== PROBLEM

BATTDATE : 1980-00-00 <==== PROBLEM

...

==== THINGS I TRIED:

- adding the device to the kernel "quirks/HID_QUIRK_NOGET" list, w/o success.

- testing it on the same VM running on VMware Workstation 7.x: it works perfectly

Any suggestions?

Thanks

I then tried "uhci.syncWriteback = true" and "usb.generic.skipsetconfi=true" w/o success.

I verified that it will work if I take the VMDirectPath route instead of USB passthrough.

Unfortunately VMDirectPath has its own issues (all configured memory is reserved, no snapshots while running, all USB devices connected to the same PCI device linked to the same VM,...).

I've been having this exact same problem with an APC XS 1500. Interestingly, while the linux driver seems to have a problem, other guest operating systems seem to be able to interact with the APC just fine. I tried installing apcupsd from pkgsrc in a NetBSD 5.0.2 guest and everything worked just as it was supposed to.

It's not clear to me yet if this is a bug in the linux HID or something idiosyncratic with the virtual usb controller, but I'm inclined to suspect the former.

I've tested in Fedora 10, 13, and 14, with both 32 and 64-bit kernels/libraries; and in NetBSD 5.0.2, 32-bit- only.

I have same problem. Did you manage to solve this?

Not exactly.  What I did was to get a Smart-UPS with a network card, and use that to monitor the status of the UPS.  The network interface provides quite a bit more information anyway.

Hello all,

I know that the topic is ancient but this time I face exactly the same problem with ESXi 5 and a Ubuntu Linux 12.04 64bit server installation together with a BackUps CPS 500.

Did anyone find a solution? I cannot use the vMA as my ESXi server has a free licence.

Thank you in advance.

Hello all,

I have a similar problem with USB passthrough.

The host server is a Fujitsu Primergy TX 150 S7 with ESXi 4.1 installed.

I connect i.e. a USB keyboard to the host server. I add the USB controller to a Win 7 VM with HW 7 and latest VM tools (no problem here).

When I try to add the USB device, it isn't possible because that option is greyed out.

I've tried this with a USB mouse and an APC UPS, always the same problem: greyed out option.

I even tried all the USB ports on the server.

Anyone got a solution for this?

I had the exact same problem using the following bits and pieces:

  • An Intel DQ77MK board
  • An APC BK350EI Back ÙPS
  • VMWare ESXi 5.1
  • A Ubuntu 12.10 VM with the latest VMWare tools installed

The idea is to have the Ubuntu VM run an apcupsd master service that other VMs can connect to so they get a chance to do something useful in the event of a power failure. And to power off the VM host too of course.

Without thinking too much, my initial attempt at making this work had me adding a UHCI/EHCI controller to the Ubuntu VM and then passing through the APC device to that controller. It worked - almost. I also got erratic behaviour and the errors below:

drivers/usb/input/hid-core.c: usb_submit_urb(ctrl) failed

drivers/usb/input/hid-core.c: timeout initializing reports

I tried a whole bunch of things, including adding quirks options to the usbhid driver, but to no avail. Finally, while taking the VM host apart for other reasons, I discovered that the actual physical USB controller I was using was a xHCI (USB 3.0) controller. I then proceeded to change the virtual controller in the Ubuntu VM to a virtual xHCI controller too - and everything worked! No delays, no errors - just apcupsd goodness.

Realizing this is sort of an anachronism in relation to the original post, I don't know if this really helps, but I see others having the same issue elsewhere - so I am hoping this helps someone 🙂

Thank you SO MUCH for digging this thread up to report your findings. I want to use apcupsd with my APC Back-UPS 500 with USB passthrough.

I can also confirm, changing the controller to xHCI works with an ESXi 5.1 server on a mordern Dual Xeon supermicro motherboard with usb 2.0 ports as well!!! Ubuntu 10.04 with vicli installed.

I tried the same trick on vma 5 (vsphere management assistant), running opensuse, after upgrading the hardware version to 9 to add xHCI support. Unfortunately, the kernel does not support it, and you get more USB errors. Looks like I have to use my Ubuntu VM.

I just want to add that I too am thankful to have found this post.  I would also add that I DID NOT have to actually connect the APC UPS through an xHCI USB 3 port in order to see the issue fixed.  Just adding the virtual xHCI controller to the VM while the APC Back-UPS was still connected through the USB 2.0 controller was sufficient.  And what a difference!  Prior to adding the xHCI controller syslog (on the CentOS 6 VM the APC was mapped to) was logging a boatload of these errors whenever I issued "apcaccess status":

     kernel: drivers/hid/usbhid/hid-core.c: usb_submit_urb(ctrl) failed

     kernel: generic-usb 0003:051D:0002.0003: timeout initializing reports

And it sometimes took five to eight seconds to get a result (often with timeouts). 

After adding the xHCI controller to the VM "apcaccess status" immediately returns a result -- every time.  And no more USB errors in syslog.  Absolutely Night-and-Day!

I can also have the CentOS VM shutdown ESXi (which is configured to suspend all VM's as the shutdown action) and the apcupsd daemon works correctly when the VM resumes (i.e. if utility power is still out, apccontrol will issue another doshutdown or if power has returned, apccontrol will issue a mainsback).  Absolutely perfect! 

To have a Linux VM actually shutdown ESXi (and suspend all guests -- provided that's the shutdown action), all you need is a shell script in /etc/apcupsd named doshutdown that looks similar to this:

    #!/bin/sh

    /usr/bin/sshpass -p myrootpassword /usr/bin/ssh -x -l root 172.16.x.x "/sbin/shutdown.sh && /sbin/poweroff"

    exit 99     #keep apccontrol from doing it's own shutdown

(Change "myrootpassword" appropriately, change "172.16.x.x" to the IP of ESXi, install sshpass, make sure ESXi has ssh enabled (maintenance mode), and ssh at least once to ESXi from the VM in order to accept the ssh signature.)  Of course you also have to configure /etc/apcupsd/apcupsd.conf as needed/desired.
