Wtf I just searched for "usb b repair" and that was the first video and this is precisely my problem with exactly the same MIDI piano 😃

[@OmoiSenpai]

Haha ^_^ That's KZbin doing it's thing :P I hope it helped ya!

[@tsom5216]

Where can i buy the port?

[@bluffgawd]

I think the three of us may have a class action law suit on our hands. I had the same keyboard that had the same issue lmao

[@raysgameplays]

Fuck I love you this the exact shit I needed literally

[@OmoiSenpai]

Hah! I knew it would help somebody! Glad I can help ya with that! Be careful with it though, Soldering can be a pain as you probably seen on the video lol.

[@raysgameplays]

@@OmoiSenpai yeah I tried once before already but struggled with getting the holes free of gunk after removing the old USB port. Didn't manage to get the new one in cause the holes were still stuffed. I think I need to get that copper looking strip you were using

[@OmoiSenpai]

I see! Yeah, it is called Solder Wick! It really works out nicely, especially if used the right way!

[@WilliDLax]

Are there other problems that affect midi keyboards?.. Cause I just got this exact one from a yard sale.. I have two USB chords.. One shakes but doesn't show up on my laptop.. The other doesn't power it on at all... Is this still a port problem or something else.. Please help

[@xenosoul1363]

what do you mean by using a battery? not sure i understand what you meant.

[@OmoiSenpai]

I used to use a battery as a way of keeping the wire pushed up, Like how you'd use a door stopper, those little triangle things, to hold a door open. That, but on the wire.

[@usbmgchannel8446]

Yo my boy omoi, I'm hearing such an annoying ringing high pitch sound from my monitors it's not just that but static and like computer sounds, WHATS UP WITH THAT?!? I got a power bank and nothing, pc and mac both do it, it's my second pair of monitors they both do it. Idk what do you think???

[@usbmgchannel8446]

And another thing I dont hear it thru my headphones gotta scarlett btw. Just my monitors sound terrible.

[@OmoiSenpai]

Hey! Do you happen to have something like LED lights near it, or any electronics? Sounds like that could be the issue if it happened to not only 1 pair of Monitors. Mines does the ring as well with my LED Strips when I have them on. They're not much of a bother to me though. I'm placing my bet on an Electrical interference!

[@usbmgchannel8446]

@@OmoiSenpai thanks for your two cents, but it's been bothering me cause I've tried alot and dont want to keep buying these monitors were expensive enough... I seen somebody go as far and removing the third prong off the wall cable I think it's called the ground, but I'm not with all that. I'm glad your dropping videos again regularly keep it up the game needs you.

[@OmoiSenpai]

Thanks! And Eek, I wouldn't even dare destroying the prong! If you want, you could experiment by using the Monitors elsewhere, and away from everything to see if you hear the ringing problem. If you don't hear the problem, then it's definitely due to an interference, rather than it being the speakers itself. Also test it out with multiple output cables.

[@shizit94]

you just saved me $200 with that little detail: Don't let the connections touch!

[@timpullen4941]

when you solderer a plug like that you should solder the big points first because this anchors the plug and when you solder the data pins you will not be putting pressure / force on the solder points on the PCB. ( I am an engineer with a keyboard company )

[@skunker505]

I had this exact problem and replacing the USB fixed it! For anyone watching, be mindful of the little pads that you solder onto (the rings around the holes where the pins go through). On mine they came right off when I was removing the old USB connector. I was able to scratch off some of the PCB material to expose the copper underneath and make a little solder bridge from the pin to the copper. It was barely making contact but it works!

[@hotpotatapie]

I just did the same thing to fix an AKAI keyboard. He seemed to have no damage to the PCB traces (donut shape pads) when he unsoldered. I guess I heated them too much, but 2 of mine came off/got destroyed, so like you, I made a little copper wire jumper and soldered that.

[@timmacdonald8141]

Thanks you two- im about to tackle my Steinberg audio card- I got the ur-rt2 so it’s scary

[@Hytherious]

guys, gotta ask because i've been looking for a solution but i just can't figure it out. took my midi controller to a solderer, he soldered the usb type B connector and now my midi plug and play controller lights up but Windows doesn't recognize it, it doesnt even make a notification sound when connecting it, seems like my laptop isn't receiving any data from the midi and i just cant figure out a solution!

[@nonholographic]

haha, I was looking for a way to tighten this usb type with pliers or something and what I got was someone violating all the rules of soldering. I dont do it much myself, but I liked watching channels like Voultar on yt for some hot tips. It's pretty interesting and he fixes up old Nintendos and things. Keep the dream alive brother

looking at the photo on the back. That's a lot of screws. perhaps there are some hidden under the stickers, or the rubber legs?

[@musicsterrible]

Had the exact same problem with my axiom 49. Thanks for the video! This repaired it. I had to make sure the solder on the 4 pins didn't touch each other. It wouldn't work at first when the solder was connecting/touching the other pins. Thanks again.

[@mrcaspper]

So how did u solved the problem whem the pc wasn't recognizing the keyboard? I mean did u soldered again or?.. pretty confused about that. I have the same problem on a 49 keys oxygen by m-audio and just ordered all the equip for the job.

[@OmoiSenpai]

The PC did not recognize it after I installed the new USB Piece, because there was a bridge of solder between 2 of the points and I did not notice it the first time around. I had to remove the bridge by re flowing the solder and removing that link. Hope that helps, and good luck!

[@JitendraWagh73179]

There is another tip on this, I too have the same keyboard with the same problem. Just Use a paper tape or medical tape and wrap it over the Usb Mal B port / the cable connecting the keyboard. Use 1/2 rounds just to make a snug fit, and it works perfect.

[@vicksindamix]

So you said you bassically wrapped your USB b cable in paper tape and it worked out?

[@avgriffin]

no matter what keyboard you get it seems like the cheap ass material they use for the usb part will break with normal use. Id pay all my money for one I dont have to become a technician to use less than a year after i got it. Its impossible to get into them with any of my tools, do I need a special one? nowhere online says. Ive bought three in last five years they just arent reliable. Might buy a custom one some day. Sick of this shit being built so cheap but a hefty price regardless. Like USB is the achilles heel are you serious? Im a music dude not a DIY electrician haahaha

[@rautshsale1948]

maybe very stupid question, but does the usb b female connector have to be new? i have an old printer that i don't use, and am wondering if i can take the female connector from it to add to my keyboard? but i never soldered anything btw, so maybe, once it's been used (and soldered) it cannot be re-used?

[@motheroats]

I have a gen 1 axiom 49, I plug the usb in and the power works perfectly fine to it but my Mac won’t recognize it and Logic Pro X, do you think the USB pot itself has an issue even if it powers on?

[@TROMO]

motheroats have the same problem :( did you find any solution??

[@dredayonnabeat]

TROMO the Usb connection has to be strong...No wiggling or quick disconnects.

[@Kendonezia]

I had same problem with my 1st generation 25. I bought a midi to USB cable and had to find a power adapter...boom

[@theorncampbell4432]

You have to find the 'Axiom Pro.bundle' file online somewhere. Download it and put it in the Logic Pro's MIDI device plugin folder. Once you've done that you, HYPER CONTROL functions will work. The 1st Gen Axioms won't work unless you do this. Cheers.

[@MrKrampyHands]

Hmmm i got a busted one if these days on my sim racing pedals its the one you use to connect to the pc its important i got it working in a ghetto sort of way but the back cap on the port stays loose i had to shim the top of the port so when the pedal if assembled it puts pressure on the port so things actually make contact and stay put i gotta have a new one soldered in this one sends power and information so i gotta find exactly what one i need to make a proper fix

[@OmoiSenpai]

Best bet I do everything :P Little bit of this and that here and there! The latest thing that is out from the norm was to build a soundproof isolation booth: kzbin.info/www/bejne/mZnZp4uugax2d7s Just, make sure not to work too hot, and don't burn the board, otherwise, you're pretty much screwed! 0,0'' No stress though! :3

Great video! Gotta do this cause I dropped my launckey. Quick note but make sure you do a clean solder with 30/70 lead tin. Looks like the right side is a dead joint which will fail after a year or so. Cheers!

[@OmoiSenpai]

Thanks! If I had Flux, it would have made the process 1000% better and I would have avoided the cold joints. I did run back it in the video, but I heavily trimmed it down to help with the retention after publishing. Good catch! ^_^

[@pimc172]

my casio has a different usb, with 4 small pins soldered on top of the board instead of the pins that go through like yours....What a shame, I have to buy a new keyboard for an obviously cheaply designer connector

If anything, the pins could be bent or cut smaller if it works. Or maybe there is a specific part for it that can be bought and fixed with. Either way. I hope it works out for ya!

only if you can get power to it...for instance a wallwart and midi would work. I had the exact keys hes working on, i gave mine away to my nephew, but i bought him a midi to usb connector and a wall wart (plug) and it works fine. Im now having the same problem with my vi49, this clears up how to fix it, but i might just go the midi powerplug route so i dont damage it. who knows maybe ill grow some nuts

Which USB port did you get

[@mikebello_music]

Hello, some days ago, someone flatted my USB cable and broke the connection, I did everything I saw in your video and it worked, the controller turns on and everything works fine on it, but when I appreciate the macbook it does not detect it, what do I do?

[@OmoiSenpai]

Hey! Did the keyboard used to work with the Macbook before this happened? Did you replace the USB Cable wire as well? I don't own an apple computer, so I don't have much experience with it, but if you never connected the keyboard to a mac before, you may have to search and install drivers for it.

[@mikebello_music]

@@OmoiSenpai If, before this happened it worked correctly, I did tests with several cables, and the cables are fine since they work with others of my controllers, and other controllers work just connect them, I have never needed to install drivers or anything, I am about to try if through the MIDI out connection it works and if it also works with another laptop

[@chrisco2323]

First, thx for this vid, watched twice. My prob though: new USB female too tight. cable insert actually makes a nice satisfying click, whereas old one seemed only very slightly loose. I've never soldered before. This is an Akai MPK88. I've tried 3 cables (male USB-C) all same. It takes some pressure going in (already too much) then that nice click. It takes a lot of pressure to unplug--way too much. So even if I was a master solderer, this would break instantly as soon as I solder new one in. Any advice please and thanks?

Before you do all this soldering you can try spraying a little Deoxit in there, it's like WD40 for electronics and helps maintain the connection. Just recently discovered it myself and it's had several uses already. Worked to fix my USB port which only worked when it was held to one side.
