| 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

Most of the usb hard drives are seen as scsi devices in Linux. I'm not
sure about firewire hard drives, sorry.
So as root, figure out how the drive is seen with; cat /proc/scsi/scsi
Got this from one of the IBM Linux support pages a while ago. I don't
remember the URL, but here's the text that I grabbed.
One of the most useful things to learn as a system administrator is how to
add more disk space if you have hot-swap drives available to you, without
rebooting the system. Without using /proc, you could insert your drive,
but you would then have to reboot in order to get the system to recognize
the new disk. Here, you can get the system to recognize the new drive with
the following command:
echo "scsi add-single-device w x y z" > /proc/scsi/scsi
For this command to work properly, you must get the parameter values w, x,
y, and z correct, as follows:
* w is the host adapter ID, where the first adapter is zero (0)
* x is the SCSI channel on the host adaptor, where the first channel
is zero (0)
* y is the SCSI ID of the device
* z is the LUN number, where the first LUN is zero (0)
Once your disk has been added to the system, you can mount any previously
formatted filesystems or you can start formatting it, and so on. If you
are not sure about what device the disk will be, or you want to check any
pre-existing partitions, for example, you can use a command such as fdisk
-l, which will report this information back to you.
Conversely, the command to remove a device from your system without a
reboot would be:
echo "scsi remove-single-device w x y z" > /proc/scsi/scsi

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.
