peewee678 Posted February 15, 2015 Share Posted February 15, 2015 Solved: http://line6.com/support/topic/12137-jtv-89f-replacement-is-ok-usb-interface-seemed-to-be-faulty-as-expected/ Hi, Updating the firmware from 2.0 to 2.1 is not possible. I tried it about 12 (edit: 30) times but each time with the same error message. Monkey is up-to-date (1.67). Guitar is detected. Green lights on USB interface both light up. Also tried flashing from file (TylerVariax_2.10.vxf). Same error... When useing the Workbench HD my guitar loses connection every few seconds. I can't save or load presets. When "rescanning" multiple times in a row it says either "JTV-59", "JTV-89F" or "Not connected". I do have a guitar cable plugged in (otherwise the guitar would not be connected at all in workbench). Already tried a different ethernet cable instead of the provided one. Nothing helps... What's wrong? I also tried this on my laptop (my music production system) but it's even worse there: the red light (guitar sise) is blinking red on the USB interface. Edit: just tried it on a third PC: green leds OK but the same connection problems... Any advice? Please... Thanks! Here's a screenshot of Monkey and the error: Quote Link to comment Share on other sites More sharing options...
jandrio Posted February 16, 2015 Share Posted February 16, 2015 try other usb port, other cable, fresh reboot, other pc.. it seems that u have a guitar-pc communication problem... Quote Link to comment Share on other sites More sharing options...
peewee678 Posted February 16, 2015 Author Share Posted February 16, 2015 I already tried 3 (!) computers and ofcourse rebooting, reconnecting, powering off the guitar, reconnecting in every order you can imagine. The problems on my laptop are even worse because the USB interface's LED is blinking red (guitar side). Can't get it to work at all. There's nothing wrong with the laptop however. I use it for music production. Everything is neatly connected. I tried everything, really. BTW: Can anyone confirm the black USB interface is not compatible with an USB 3 port? On my other PC (USB 2) the USB interface does work but I'm still having those communication problems. Can't flash the firmware, can't write patches. The guitar is detected as a JTV59 but als as a JTV-89F (rescanning in Workbench gives me alternate guitars...). Quote Link to comment Share on other sites More sharing options...
wilson69978 Posted February 16, 2015 Share Posted February 16, 2015 Hello peewee, sorry to hear you are having trouble, I was thinking of buying one of these guitars but now I am starting to have doubts. A few guys have had similar problems. I hope you resolve them soon. Quote Link to comment Share on other sites More sharing options...
wilson69978 Posted February 16, 2015 Share Posted February 16, 2015 I just thought of something Peewee. Have you made sure all other applications are closed on your computer while you do the update? Also If you have more than one computer on a network running at the same time, try closing it's programs and put it to sleep or shut it down while you update. Sometimes interruptions from other devices can cause download problems. Quote Link to comment Share on other sites More sharing options...
Charlie_Watt Posted February 16, 2015 Share Posted February 16, 2015 I would suspect the USB interface. They are garbage. Many of them do not work. I would work with Line6 to get a replacement. Your guitar is probably fine. Quote Link to comment Share on other sites More sharing options...
peewee678 Posted February 16, 2015 Author Share Posted February 16, 2015 @Wilson: yeah, I had no programs running while updating. The problem is much worse however: I can't use workbench either (firmware in my guitar is 2.00). I have contact with alan2803 who has the same problems (firmware 2.10) and there is someone else today new on the forum with almost the same problem. It's not a download problem either because I also tried flashing from a downloaded file. Also: Workbench behaviour gives me all the reasons to know it's a problem with the connection between the guitar OR USB interface and the PC. It says "none" detected (most of the time) OR JTV-59 OR JTV-89F after rescanning but even it's a JTV-89F (my model) Workbench gives errors while uploading/downloading presets. Thanks. @Charlie: I also suspected that but alan2803 PM'ed me he had the same problem connection via his POD so that would mean it's the guitar. Not sure in my case however. I'll get a replacement tomorrow but I'm starting to think there's maybe something wrong with a whole series of guitars maybe (or USB interfaces indeed...). Thanks! Problem is: can't get a USB adapter (they don't sell them here in Holland) to troubleshoot so I have to return the guitar with it... Quote Link to comment Share on other sites More sharing options...
