Thanks in advance for any response...

I would like to know how to unplug/disable the usbdevice from redhat9
without physically unpluging it.  The purpose of the is so my usb device,
which is a scanner, can be seen by vmware.

Is there a command that will do this?

The usbmodules command only has these args... Usage: usbmodules [--help]
[--device /proc/bus/usb/NNN/NNN] [--check module]
[--mapfile pathname] [--version]
Lists kernel modules corresponding to USB devices currently plugged into
the computer.
When I run ./usbmodules --device /proc/bus/usb/001/002 I get ... "scanner"
as the result.

The lsusb usage is the following...
usage: lsusb [-v] [-x] [-p <procpath>] [-s [<bus>:][<devnum>]] [-d
[<vendor>]:[<device>]]

here is a copy of my lsusb command... Bus 001 Device 002: ID 03f0:0405

You can't do what you want. The USB standard does not support this
behaviour.

Try the following:

as root: /sbin/rmmod scanner

Then select the usb device under "Device" in the vmware window.

Thanks again.

WOW

I'll pass this on to a few others that had this same problem.

Glad that it worked. If you want to do the opposite, then just disconnect
from the vmware window (under "Device by selecting "none") and type

as root: /sbin/insmod scanner

and you should get control of the scanner in linux then.

Thanks for the additional info.  It's a win only hp scanner so I probably
won't need to ever give it back to linux.

But would this also work for usb hard drives or firewire hard drives?

Thanks

TBH, I dont have much experience in using vmware, but AFAIR usb hard
drives and zip drives should work, provided you remove the appropriate
module...so for a usb drive it should be "usb-storage".

The last time I checked vmware, it didnt have firewire support, so I
am unable to help you there. Instead of working with vmware, I found it a
lot easier to network and run two separate PCs.

cheers

SG.
