Subject: USB/VMWare question
Date: Tue, 16 Nov 2004 04:40:28 +0000 [thread overview]
Message-ID: <20041116044028.GA11922@fmp.com> (raw)
This may be a VMware issue, and may be something that can be corrected by
configuration, or it may be an issue that needs addressing in Linux
hotplugging. It's an issue that could cause a lot more trouble than it's
causing me, for instance if a USB printer were involved rather than simply a
USB storage device.
I'm using Gentoo Linux w. kernel-2.6.9, udev 043, plus VMware workstation
4.5.2 build-8488. I have VMware configured to automatically connect new USB
devices to the virtual machine when it has the focus.
If the usb-storage module is _not_ installed and I connect a USB storage
device to the system, the VMware guest OS (Windows 98SE) correctly detects
and mounts the device; however, the host OS simultaneously installs the
usb-storage kernel module. This doesn't appear to interfere with normal
operation in the guest OS, which can access the USB storage device normally.
If the USB storage device is unplugged and then re-plugged, however, the
presence of this module in the kernel causes VMware to complain that the
device is already in use in the host OS and can't be used in the guest
system, and the device doesn't work.
I can get around this each time by unplugging the USB storage device,
rmmod'ing usb-storage in the host OS, giving the guest OS focus again, and
then re-inserting the storage device. This is an obvious PITA. Is there
some way to provide conditional module insertion to the hotplugging system?
I need to be able to use the USB drive in both Linux and the guest Windows
OS, so the usb-storage module is necessary. I would just like some way for
the host OS to know that VMware is running and not insert the usb-storage
module in this case.
