+Captain Gore-tex Posted February 11, 2011 Share Posted February 11, 2011 Rather hoping someone may be able to assist. My Oregon 550t has been working perfectly for some time but, without any changes to software etc it now fails to connect to my PC leaving me unable to upload any caches. What Happens? On connecting to my laptop by USB the oregon screen goes to the one with the computer connected to a GPS picture as normal but instead on halting there allowing you to see the oregon in 'my computer' it then moves to normal start up and shows the external power source icon where the battery icon usually is. What I have tried: hard reset switching to spanner mode and back the advice on the Garmin support page (hold power on button then connect USB cable, release) reloaded Garmin drivers to laptop tried different PCs found similar issues raised by a few users on the forums but no solutions I don't know what else to try, anyone got any ideas 9other than emailing Garmin support which is my next step if this post doesn't help. Many thanks for reading. Quote Link to comment
+dfx Posted February 11, 2011 Share Posted February 11, 2011 have you tried a different cable too? Quote Link to comment
+mpilchfamily Posted February 11, 2011 Share Posted February 11, 2011 Or a different USB port on the laptop? Quote Link to comment
+quadsinthemudd Posted February 11, 2011 Share Posted February 11, 2011 have you tried a different cable too? fixed mine that way once. Quote Link to comment
+Captain Gore-tex Posted February 11, 2011 Author Share Posted February 11, 2011 Yes checked different cables and different computers so I am fairly happy it is an issue on the Oregon itself. Quote Link to comment

There's a few things listed on http://garminoregon.wikispaces.com/Miscellaneous that you can try, which you may or may not have already tried, espcially the "forced USB mass storage mode". I don't think there's anything else you can do that's not listed on that page. Quote Link to comment
+splashy Posted February 11, 2011 Share Posted February 11, 2011 Are you using a bare Usb cable or is it in any way connected to an Usb hub? A Sd card in the Gps? Quote Link to comment

I don't think there's anything else you can do that's not listed on that page. Interestingly the "forced USB mass storage mode" wont work on the unit. I have now tried with and without the SD card, with and without batteries, all to the same result. I think it is going to be a 'Help me please Garmin' message, I have to say they have previously been excellent at resolving issues. Edited February 11, 2011 by Captain Gore-tex Quote Link to comment
+Chrysalides Posted February 12, 2011 Share Posted February 12, 2011 If you've already tried all that, your options are down to : connecting it to the computer and leaving it for 1/2 hour to see if it eventually connects, and a master reset. Quote Link to comment

Did your GPSr have issues before this started where if you moved it or bumped the cable it would disconnect? Does the cable connector seem to be loose? I ask these because my Oregon 400t had started acting like that before it got to the point where it would more often not connect that it would connect. Since my unit was out of warranty I decided to pop it open to see what I could see. In my case, the ribbon cable that connected the USB port to the system board in the GPSr had come loose on the port connector end. It uses a fragile "ZIF" cable connector and the "lock" had apparently worked its way open over the years of use, and the cable was not always making contact. After reseating the cable, it has worked fine. I wouldn't recommend anyone else try this on their own, but instead that they call Garmin, as they are pretty good with out of warranty repairs. I don't know why I didn't call them myself, but I got lucky. Quote Link to comment

It does connect, unfortunately it goes from mass storage to normal mode, that is the issue, hence unable to upload caches to the unit. I dont see leaving it for 1/2 an hour will do anything differently, email to garmin sent, I will update the thread once this is sorted. Quote Link to comment

Yeah, if it goes from mass storage to normal mode, leaving it connected wouldn't help. I didn't read carefully, I thought it just refused to connect. My Oregon sometimes connect immediately, and sometimes take a few minutes to connect. Very strange. Quote Link to comment
savant9 Posted February 13, 2011 Share Posted February 13, 2011 Leave it on spanner mode, and try a new usb cable. My friends 450 did the exact same thing all the time, and that is all I had to do to fix it for him. Quote Link to comment
+Cacheoholic Posted February 13, 2011 Share Posted February 13, 2011 What does the GPS do when you are holding in the power button for 30 – 40 seconds initiating the forced mass storage mode? Quote Link to comment
+Captain Gore-tex Posted February 24, 2011 Author Share Posted February 24, 2011 Thanks for all the posts suggesting help. It went back to Garmin on Monday and by the same Thursday I had delivered a new (or refurbished) unit back. Top quality service from Garmin, I really cant overstate the quality of service from Garmin UK. Quote Link to comment
diego[HUN] Posted June 1, 2012 Share Posted June 1, 2012 What does the GPS do when you are holding in the power button for 30 – 40 seconds initiating the forced mass storage mode? My warm thanks. You Saved me a 215$-os because of a service prize. Very Very Thank's Quote Link to comment
+Rikitan Posted November 1, 2013 Share Posted November 1, 2013 Same problem. USB Mass Storage mode worked well with my Oregon 550 for like 2 years. Now it does not. Using same cables, USB ports, no FW upgrade, no SW change. It simply stopped working. Forced mode can't be initiated neither. This is really annoying .. Quote Link to comment
+AndyT1 Posted November 1, 2013 Share Posted November 1, 2013 Try a new / different USB cable. Had the same issue with my Oregon 450, new cable solved the problem. Quote Link to comment
+BAMBOOZLE Posted November 1, 2013 Share Posted November 1, 2013 Try a new / different USB cable. Had the same issue with my Oregon 450, new cable solved the problem. 10-4, cables do go bad.....happened to me too. Quote Link to comment
+AndyT1 Posted November 1, 2013 Share Posted November 1, 2013 Funny thing was the cable I had always used was permanently plugged in to my PC, never transported around or even moved from computer to computer. Started off only connecting on every second attempt and went downhill from there. So what is there in a USB cable that can go "bad" ? Quote Link to comment
+dncburrhead Posted August 31, 2014 Share Posted August 31, 2014 I've tried all the things mentioned in other replies, including taking it apart to check the connections, and clean contacts.My GPS connects to the computer, but then a window pops up saying the device attached to the USB port has malfunctioned, then a few minutes later the main menu comes up on the GPS screen. I have gone through the problem of having to connect mulitable times for it to finally connect. There are other issues. 1- Being when I do a reset for the trip computer, everything goes to Zero as it should. But when I check it, say 500m later it may read that I have gone 4.38km, as an example. I do another reset and it is usually fine. 2- Often the compass points in the opposite direction it should, even if I do a recalabration for the compass. Other than that most of the problems I have are because of the operator. May to give up Caching. Do not want to spend another $600.oo plus for a neww GPS Quote Link to comment
+splashy Posted August 31, 2014 Share Posted August 31, 2014 You ARE aware this thread is from 2011>> Last message 2013, what gps are we talking about? http://garminoregon.wikispaces.com/Miscellaneous see section about Recovery #1 But it sounds like a lose (moving not tight) connector.
