The VMkernel log reports the log spew: usbdev_ioctl: REAPURBDELAY (1029451)

Resolution

This issue is resolved in VMware vSphere 4.0 Update 3. This debug logging message does not indicate an issue and may be safely ignored.

However, to reduce the amount of logging, you can retune the USB drive module to stop logging these messages.

To retune the USB driver module:
  1. In the VMware vSphere Client, evacuate the virtual machines from the ESX host by performing a vMotion to peer hosts or shutting down the virtual machines.
  2. Log in to the ESX host's terminal via SSH, the System Management Interface, or directly at the console.
  3. Run this command:

    esxcfg-module -s libusb_support=0 usb.o

  4. For the changes to take effect, run one of these commands and reboot the ESX host:
    • shutdown -r now
    • reboot

Additional Information

To revert to the original configuration, run this command and set libusb_support to 1:

esxcfg-module -s libusb_support=1 usb.o
