Kore 1 controller not loaded by Windows XP until after I re-insert the USB plug

It sounds to me like power management to the hubs got turned back on somehow... make sure that it's turned off for all your root hubs.

If it is, contact support and PM me your ticket number.

The Kore 1 device seems to come up as a Unknown USB device in System Hardware Devices. I uninstalled that first.

I just re-installed Kore 1 again (following all your suggestions) this time unplugging the usb cable from the port on the back of the PC and then putting it back in there (instead of just unplugging from the Kore 1 usb port itself). I'm not sure that can make any difference but who knows?

Power to the hubs was still off BTW

After a re-start the Kore 1 device is recognized.

I will need to see this happen after a cold boot to be convinced that it is now fixed.

Perhaps the usb cable really does need to be removed from the actual PC end when re-installing usb devices?

I don't know why that would be the case but perhaps they designed it that way.

 

That shouldn't make any difference, but if it works, all's good.

Well, after a cold boot the same problem persists. Kore 1 not showing up in devices except as a usb with a yellow triangle (not working).

So as long as I don't switch off the PC....

 

I'd almost be tempted to have your power supply checked out if I were you. It sounds like you aren't getting enough power to the ports when you first start up.

Ah- one other idea, though. Is your USB port hard connected to your mainboard's back panel or connected via a header? You might want to open your machine and make sure all the cables going to the headers are attached firmly.

Hi, this is really very odd... I am certain that I have replied to this thread at least once and yet my messages are missing.

Here is the gist of what I attempted to post after the previous message from EW:

After a cold re-boot the PC did not lock onto Kore 1 device.

So I am no better off than when we started this thread.

I will attempt to use Kore 1 on my laptop shortly and see if that works.

Its not the power supply which is a 500 watt unit.

Its connected through the usb 2 backport and worked fine.

I have quite a few usb devices such as Guitar Rig 2, Korg M3 and the Behringer BCR2000 (all plugged into the rear usb 2 ports) and also several usb devices on the front usb ports.

Like I said Kore 1 used to work just fine.

I will try disconnecting some other usb 2 rear devices (or at least one of them) to find out if that might enable the Kore 1 device fully.

 

Your replies are auto-merged if you post twice within a certain time frame without anyone posting inbetween.

See two posts above... there's your post.

How can you be sure? Do you have any other USB 2 devices that require a full 500 mA on startup?

Sounds to me like you're running out of bandwidth. How much is the M3 using?

The M3 is not even turned on - nor is the Behringer BCR 2000 when this happens.

The Guitar Rig 2 does have power from the usb.

This was never any problem.

 

I'm still having the exact same problem with the Kore 1 device not being detected fully.

I just hope that this problem does not indicate an more serious problem is about to happen.

Just for the record my power supply is 500 watts.

 

As I've said, contact support, and provide a link to this thread.

Still the same problem with a so called fixed Kore

I sent my original Kore back through a support ticket and received another one (just packed in some cardboard supports - and it was not my original I assume - without my original product box) and I still have the same issue.

Windows XP does not lock onto the Kore device after booting unless I unplug the Kore and then plug it back in.

Apart from asking for my Kore product box back I am at a loss as to what to do now.

The problem is relatively small (in the scheme of things) but is really annoying at times.

 

If that's the case, it sounds like a PC issue to me...

Its a clash with Guitar Rig 2 - if I unplug that then Kore becomes the 'default' usb audio device.

Still is an issue though. Surely they could fix this. I'd say its an issue that NI might be able to address.

 

Ah...

The Kore controller's using 89% of your USB 2 controller's bandwidth- there isn't enough bandwidth on the controller for both, I'd think. And, for your scenario to work, the drivers would have to be identical instead of just the audio part being identical as it is now; then they could share drivers. The ASIO spec only allows for one driver to be acvtive at a time.
