1. I get this error what can I do?
   Error: Writing to usb bulk endpoint: Connection timed out

   There are some problems with the usb connection!
   To solve this:
   1. Don't turn off the camera for this!
   2. Pull off the usb cable from the camera.
   3. Wait 3 seconds.
   4. Insert the the usb cable to the camera again.
   5. Wait 3 seconds -> 
      If the kernel detects the camera, there should be a beep!
   6. Try your commandline command again!



2. I get this error what can I do?
   Error: Writing to usb bulk endpoint: Operation not permitted

   1. Please try it again as superuser. 
   2. If that works and you want this to work for a
      normal user, you must do the following:
      Edit as superuser the hotplug configuration file
      /etc/hotplug/usb/usbcam.usermap  (SuSE8.1/8.2)
      /etc/hotplug/usb.usermap         (redhat 8.0)

      Add at the end of that file the output of
      the command.
       ./hp215 -puu
      Save the file and it should work as normal user!



3. If I try to insert the cable into the camera if the camera is on
   the display changes normal to "PC" but no beep of the detection of 
   the camera will accur and after 5-10 Second the "PC" String in the
   display will disappear to the normal camera mode.

   Happens sometime in the -gp mode on SuSE7.2
   And very very rare in the on SuSE8.2

4. Will you add a GUI ?

   No because this programm will be added to gphoto2
   and gphoto2 has a gui.


5. Why isn't your work included in gphoto2 ?

   -  I did started working on this.
      After version 0.2.3 more in this way will be done!


6. I get something like this if I use the -gpa mode only
   -D- Receiving picture header ... OK!
   -D- Sending ACK ... OK!
   -D- Receiving picture ...
   -E- Error opening (null) for write
 
   This is a bug in the 0.1.9 version use -gpa and -gta 
   OR
   Update to version 0.2.3 and use -gp (-gpa is obsolete)



7. I get this:
   Warning: Picture may be corrupted...
   What should I do.

   - Look with an picture viewer if the picture is really 
     corrupted. Mostly this is not the case.
   - If it is corrupted try it again. 
   - Or try to get only that picture 
     example: if it is picture 5
              hp215 -no 5 -gp
   

8. It doesn't work! What can I do ?

   1. Try answer of question 2
   2. try answer of question 1
   3. Try it with the -2 option
   4. Try it with greater timeout values example 5000 etc.
   5. Send me an output
      - use the --debug option for detailed output
      - send the output to me with some infos about 
        + what you have done 
        and your
        + libusb version (locate libusb), 
        + linux version  (more /proc/version) 
        + hotplug version (??)
        + distribution version 

   Give me feedback!
