## and you can simplify this even more:

- 

def ask(msg)  
loop do  
print "#{msg} [y/n]: "  
response = gets().strip  
return true if response == ‘y’  
return false if response == ‘n’  
puts “Invalid response. Please enter y or n”  
end  
end

def find\_device  
puts “We are now trying to find the device”  
Dir["/proc/scsi/usb-storage/\*"].each do |usb\_dev|  
usb = File.read(usb\_dev)  
return usb if ask(“Found in #{usb\_dev}: #{usb}. Is this your  
device?”)  
end && nil  
end

## procdata = find\_device

- 

cheers

p.s.: I have no /proc/scsi/usb-storage (win2000) so this is untested.

Tested and am glad to get the following:  
$ ruby find\_usbdev.rb  
We are now trying to find the device  
Found in /proc/scsi/usb-storage/3: Host scsi3: usb-storage

Product: Cruzer Mini  
Serial Number: 2004351462080892ebd0  
Protocol: Transparent SCSI

. Is this your  
device? [y/n]: y
