Yes - start with a decent request - details like misbehaviour, error messages, file / directory structures, input data, execution logs, ...
This the only output I get. Normally my version of find does not give any output when it does not find something so I added the execute option. Thats why it was so difficult to figure out.
I figured it out. There were several problems. Since I am using a variable I can not use single quotes so I switched to double quotes. This created a new problem. Asterisks do not behave as expected in double quotes. It does not matter if you use a one, two, three, or four backslashes.
I have seen seen from a lot of trial and error this works.
This did not work. Is there a way to use an asterisks in double quotes with find?
Hi Guys,
Wondering if anyone can help me. I have a find command on a Linux box that works as expected:

sane-find-scanner - find SCSI and USB scanners and their device files
SYNOPSIS
sane-find-scanner [-h|-?] [-v] [-q] [-p] [-f] [-F filename] [devname]
DESCRIPTION
sane-find-scanner is a command-line tool to find SCSI and USB scanners and determine their Unix device files. Its primary aim is to make
sure that scanners can be detected by SANE backends.
For SCSI scanners, it checks the default generic SCSI device files (e.g., /dev/sg0) and /dev/scanner. The test is done by sending a SCSI
inquiry command and looking for a device type of "scanner" or "processor" (some old HP scanners seem to send "processor"). So
sane-find-scanner will find any SCSI scanner connected to those default device files even if it isn't supported by any SANE backend.
For USB scanners, first the USB kernel scanner device files (e.g. /dev/usb/scanner0), /dev/usb/scanner, and /dev/usbscanner) are tested.
The files are opened and the vendor and device ids are determined, if the operating system supports this feature. Currently USB scanners
are only found this way if they are supported by the Linux scanner module or the FreeBSD or OpenBSD uscanner driver. After that test,
sane-find-scanner tries to scan for USB devices found by the USB library libusb (if available). There is no special USB class for scanners,
so the heuristics used to distinguish scanners from other USB devices is not perfect. sane-find-scanner also tries to find out the type of
USB chip used in the scanner. If detected, it will be printed after the vendor and product ids. sane-find-scanner will even find USB scan-
ners, that are not supported by any SANE backend.
sane-find-scanner won't find most parallel port scanners, or scanners connected to proprietary ports. Some parallel port scanners may be
detected by sane-find-scanner -p. At the time of writing this will only detect Mustek parallel port scanners.
OPTIONS -h, -? Prints a short usage message.
-v Verbose output. If used once, sane-find-scanner shows every device name and the test result. If used twice, SCSI inquiry informa-
tion and the USB device descriptors are also printed.
-q Be quiet. Print only the devices, no comments.
-p Probe parallel port scanners.
-f Force opening all explicitly given devices as SCSI and USB devices. That's useful if sane-find-scanner is wrong in determining the
device type.
-F filename
filename is a file that contains USB descriptors in the format of /proc/bus/usb/devices as used by Linux. sane-find-scanner tries
to identify the chipset(s) of all USB scanners found in such a file. This option is useful for developers when the output of "cat
/proc/bus/usb/devices" is available but the scanner itself isn't.
devname Test device file "devname". No other devices are checked if devname is given.
EXAMPLE
sane-find-scanner -v
Check all SCSI and USB devices for available scanners and print a line for every device file.
sane-find-scanner /dev/scanner
Look for a (SCSI) scanner only at /dev/scanner and print the result.
sane-find-scanner -p
Probe for parallel port scanners.

SUPPORTED PLATFORMS
USB support is limited to Linux (kernel, libusb), FreeBSD (kernel, libusb), NetBSD (libusb), OpenBSD (kernel, libusb). Detecting the vendor
and device ids only works with Linux or libusb.
SCSI support is available on Irix, EMX, Linux, Next, AIX, Solaris, FreeBSD, NetBSD, OpenBSD, and HP-UX.
BUGS
No support for most parallel port scanners yet.
Detection of USB chipsets is limited to a few chipsets.
