This restores the MTPAV to factory settings *(erases and user data).<\/p>\n<p>   Make sure that you have all of the software updates for the G3 or G4.  Check Apple System profiler (in your apple menu) for ROM versions.  Then compare to latest rom versions at http:\/\/asu.info.apple.com<\/p>\n<p>   Try replacing or removing USB devices from the USB bus.  If you have a Hub, try connecting the MIDI interface directly to the Mac.  If you have a USB scanner, a hub, a USB QuickCam , etc, remove them and start small.  Connect only the Keyboard\/Mouse and MIDI interface.  If you still encounter a problem, try substituting an ADB keyboard if possible.<\/p>\n<p>   Try replacing cables.  If you are using the USB extension cable that came with the G3, remove it and connect the keyboard directly. Try a different USB cable for the MIDI interface.  <\/p>\n<p>   Lastly, look for offending extensions, try zapping PRAM, and rebuild the Desktop.  In one recent unrelated case, a user was having a problem getting his MIDI interface to scan in FreeMIDI.  We tried the normal procedures, but in the end, running off a cleanly installed OS on a different partition was the fix.  There was just something funky in the <br \/>system that we could not find.  <\/p>\n","protected":false},"featured_media":0,"template":"","categories":[],"tags":[33929,34565],"storecat":[],"itemids":[],"manufacturers":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<meta name=\"description\" content=\"Check out the MTPAVUSB constantly loses contact w\/computer.  clockworks freezes on launch or mouse locks up.
