USB Device Configuration May Cause Error During System Boot

Systems using the USB-UHCI device driver with the USB 2.0 interface cause the ESX Server to show a false warning message during the boot sequence.

Systems using the USB-UHCI device driver with the USB 2.0 interface cause the ESX Server to show a false warning

message during the boot sequence. The error looks like this on boot-up:

Mar 29 11:04:10 vmserver1 rc.sysinit: Initializing USB controller (usb-uhci): succeeded

Mar 29 11:04:10 vmserver1 modprobe: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters

Mar 29 11:04:10 vmserver1 modprobe: /lib/modules/2.4.9-vmnix2/kernel/drivers/usb/usb-ohci.o: init_module: No such device

Mar 29 11:04:10 vmserver1 modprobe: /lib/modules/2.4.9-vmnix2/kernel/drivers/usb/usb-ohci.o: insmod /lib/modules/2.4.9-vmnix2/kernel/drivers/usb/usb-ohci.o failed

Mar 29 11:04:10 vmserver1 modprobe: /lib/modules/2.4.9-vmnix2/kernel/drivers/usb/usb-ohci.o: insmod usb-ohci failed

Mar 29 11:04:10 vmserver1 rc.sysinit: Initializing USB controller (usb-ohci): failed

It is safe to ignore this message, but if you want to configure your system so that this warning does not appear the next time you boot your ESX Server machine, follow these steps

If you want to use a USB hard-drive to copy files from the ESX server to it – and you have these errors -then a general work around is to boot to a Knoppix Boot CD and do it that way. Remember if you are copying virtual disks – these will have to be exported to the COW format first.

If you have no errors like me then this is how you can go about using USB hard-drives and devices
