Real tone cable working on PC but not in game

[Fork in the Ch0de]

My Real tone cable has stopped working in game after only an hour of gameplay. It has also changed its name in devices from the original 'Rocksmith audio device' to 'USB PnP audio device' and it is not picked up by Rocksmith at all as it just says my cable is unplugged. The cable works fine for recording my guitar on just sound recorder and I have tried the usual reinstalling of drivers. I have also tried changing the microphone levels and format but to no avail. My USBs all have enough power to run the cable too. I have no idea what else could possible be wrong other than my computer just not recognising the cable properly, any ideas? Thanks!

While the cable does not need any special drivers (it uses the standard Windows USB audio device driver), it does need to have it's unique ID present for the game to recognize it.

I woudl suggest uninstalling the cable, then plug it back in to reinstall it. It should detect and install as the "Rocksmith USB Guitar Adapter".
If it does not, you can try rebooting and plugging it into another port.
If there are still problems we can try yanking out everything USB related (may cause problems with other USB devices) and let windows reinstall everything (allows it to completely rebuild the USB device tree)

I have tried uninstalling, rebooting and reinstalling the cable, all to no success unfortunately as it still shows up as the 'PnP audio device'.
To completely reinstall everything do I uninstall all USB drivers then reboot?

First, if possible I'd suggest attaching the cable to another computer just to confirm it will install and work normally. If the same behaviour happens on another system that might imply a physical defect with it (though I'm kind of doubting it).

Try other ports too if you haven't done that.

Basically you need to disconnect all USB devices and uninstall EVERYTHING from under the "Universal Serial Bus Controllers" section, then reboot. Windows will begin to redetect and reinstall all of teh USB controller hardware. You can then reconnect your USB devices. Most should install again without any real issue, but USB printers and other devices may sometimes not work right till their software packages are completely reinstalled.

I've tried the cable on a friends laptop, it comes up again as a PnP audio device and appears to work fine to record guitar sounds. I've also uninstalled everthing as you said and rebooted, the cable reinstalled as a PnP audio device again, and did not work on Rocksmith.
Perhaps the cable is just faulty after all?

Where did you get your cable?

Even without your friend having Rocksmith to fully confirm i'd say yeah probably. The cable should ID as "Rocksmith USB Guitar Adapter". if it's not then that suggests that it's identification information is possibly damaged which might be why it's detecting as just a standard USB audio interface instead.

It is possible that the USB ports are either all USB3.0 or under powered if the cable id is wrong, try a powered USB2 hub

Apparently the Real Tone cable does not like USB3.0, this is mentioned in the win10 support thread over on the UBIsoft forum

My Realtone cable(s) work fine on all my systems with USB 3.0 ports. On a system or 2 I did have to adjust BIOS settings.

If the device does not have a yellow mark in device manager and is recognized as Rocksmith USB Guitar Adapter, then all is installed as should be.

If it still won't work in the game, then something ... either another app or device ... is getting in the way (or see below for broken guitar cable portion of the realtone cable).

Remove any gamepad / joystick controllers and any other mics or USB audio devices.

Make sure no background task are stealing the cable. Just kill any other audio apps.

Also if the game never says the cable is not plugged in, the the game is working with the cable, and you actually have another problem.

Such as...

It is possible the portion of the cable from the A/D converter (the little box) to the USB plug is working , but the wire from the A/D to the 1/4" guitar plug is broken. The game would think the cable was fine, but you'd never get any signal from your guitar.

The device does not have a yellow mark in device manager, however it isn't recognised as Rocksmith USB guitar Adapter, instead it is named 'PnP audio device'. The very first time I plugged it in it was recognised as the Rocksmith adapter but not since then.

My USB ports all have enough power, I'm unsure to if they are 3.0 or not though.

The game just says my cable is unplugged every time I try it. I've also installed audacity and the cable records fine, but for some reason rocksmith does not detect it.

[rcole_sooner]

My guess is that another audio application is grabbing the cable when it is plugged in.

Or another USB device is causing issues.

Disable any other audio application from booting up, or kill them.

Remove any other USB devices from your system (except keyboard, mouse, and realtone cable).

Then go into device manager and uninstall the "realtone cable driver".

Then unplug and replug the realtone cable.

May need to reboot after the uninstall.

If that does not work, it may be some BIOS settings like disable xhci or enable legacy support on the USB 3.0 ports.

But, yeah, you need to get it to say Rocksmith USB Guitar Adapter in device manager.

It could also be a USB power thing. Some people have had to get USB powered hubs to get enough power.

Also if it is a laptop try it plugged into wall power, that may help a lot of things.

[Fork in the Ch0de]

Tried step by step as you said above, and I also enabled legacy support in BIOS, with still no success. I've checked the power levels of the USB ports by following the set up guide on the Ubisoft forums and these all seem fine too.

I have tried the cable on another friends laptop and again it shows up as the 'PnP audio device' so I'm thinking the cable may just be faulty, which would be annoying as it has only ever worked once!

It's known (And has been stated by Jason from Ubi) that the cable will id as "Hocksmit" when that's the case.

This isn't just simply a matter of the cable being underpowered. It only requires 100m of power which isn't that much and should be easily provided by any charging ports so long as there isn't too many other devices on the same root hub already taking up power.

The problem is that it's unique id isn't being sent/detected, it's sending/showing the default usb dac id. This suggests to me that the identification information in the cable is damaged or was never working right to begin with (not likely if it was working previously).

There is a known compatibility issue with USB 3.0, but I don't think that's the case here either. (Though when it is you can work around it by either turning off xCHI, use a powered USB 2.0 hub, or

It's most likely just a defective cable. The mere fact that it does the same thing on two different systems tells us that it's the cable, not the system.

I can't see that being the cause, it's just not sending the right device id, it's sending the default id instead..

OP, I sincerely believe that you have a defective cable, which is, as far as anyone knows, INCREDIBLY uncommon. You just got unlucky, it happens.

You can try it on more systems if you want to further confirm, but I think you just need to get a replacement. You imply that it's a new cable, so if this is the case the seller should provide you with a replacement.

[rcole_sooner]

I agree at this point a defective cable sounds like a reasonable conclusion.

Did you try reseating the break away connection on end closest to the USB plug? Sometimes just disconnecting and reconnecting that helps.

[Fork in the Ch0de]

I've just ordered myself a new cable and should get a refund for the other one, hopefully I'll have better luck this time! Thanks for all your help guys, I'll update you on if this one works or not :)

Late to the party, but the cable is actually 2 cables, did you make sure they were pushed in tight? I had a similar problem.
