Removing iTunes may have removed the driver for the IPod.

Also, check the MMJB site for any iPod drivers for MMJB. 

But, I suspect the removing ITunes caused the problem and you will probably have to reinstall it.

 After I started seeing this problem, I removed iTunes hoping it would eliminate the problem. I only installed iTunes a few months ago so I could use an iTunes gift card.  I have used MMJB to manage my iPod music files for over a year.

 I'm not sure that I would recognize a driver, but there are many files in the MMJB folder with ".dll".  Those may be drivers.

I've got updates from MMJB and some of them were to support various MP3 players.  Check the MMJB download site and if there is one for the iPod, download and install it.  The one that you have now may have got corrupted.

I have MMJB 10.0 (not plus).  I find no downloads for iPod on the MMJB website.  MMJB says there are no available updates.  I've tried to use the updater in my iPod folder, but it won't allow me to, except to completely restore to factory settings and remove all music.   

I currently have 2.0.1 software on the iPod.  I have already downloaded but not installed some new software for the iPod.  I imagine that if I do that it'll erase all my music.  It is a file designated setup.exe and is version no. 3.8.0.  Should I install it? Can I install it if my computer won't recognize the iPod is there? .

Another observation:  If I try to run the iPod Updater without the iPod connected, it says the iPod is not connected. If I do the same with MMJB open and the iPod connected, it says "Updater detected other appplications accessing iPod. - - -".  This seems to suggest that MMJB can tell that iPod is there, but can't recognize it, so possibly the iPod software is corrupted.  Help!

I have now resolved this problem, but not without taking drastic measures.  After my last reply, I did install some new iPod software on my computer.  Not only did that not solve my problem, but I deleted all my music.  Then, when I was searching the Musicmatch website, I found, at wwws.musicmatch.com/faq/IPOD054.htm, a note that says "Conflict with iTunes for Windows prevents transfer to iPod".  I had already removed iTunes, but this note says that iTunes corrupted the plug-in that allows the iPod to communicate with MMJB.  I could not find a plug-in on the Musicmatch website, but I finally found it on the Apple website. Even though I had already removed and re-installed all the pertinent software, the problem was not solved until I followed the procedure in the reference above.  A link to the Apple website can be found at the very end of the note at wwws.musicmatch.com/faq/IPOD056.htm.  A bonus to all of this is that my music now transfers much more rapidly to my iPod than it did originally.  I don't know why.
