Unknown Device Driver
Tarja Hempton
Hello, I have newly purchased HP notebook model HP 14Q CS0009TU. I have installed Windows 10 64 bit on it. But in device manager there is a unknown device shown. And I can't get it installed. Its location is showing that on "Microsoft ACPI-Compliant System" and status is showing that "The drivers for this device are not installed. (Code 28)" Please suggest me how to get it installed ?
If your computer doesn't recognize your Arduino and won't install the proper drivers, this fix may work. I used it for my Arduino UNO with Windows 7 64-bit, so steps may vary for other devices and operating systems. I'm writing this from memory so sorry if there are some gaps.
I tried this and many other win 7 fixes, i have win 7 x64 and nothing worked. It showed up as a unknown device and when i try to point to the driver it starts to install but says a driver could not be found. I did about a hundered things and then i did this:
My solution was to move the driver for arduino uno rev 3 to the C:\Windows\inf\ folder. Then uninstall the unknown device unplug it plug it back in adn it took like 5 seconds to intall i was so happy. I only post this because it wasnt on most of the threads like this one it didnt work for me.
Thank you! Tried to get my new UNO R3 working on Linux first and could not. Switched to Win 7 and was very disappointed to hit essentially the same error. Found your post and fixed right away. Thank you. Thank you. Thank you.
I had this issue where the driver was not getting recognized. It turns out it was the USB cable itself. Make sure the cable is newer and not a USB 1.1 cable. As soon as I changed the cable it worked fine.
Thank-you both for the suggestions. I had previously tried to re-install the 3 packages you mentioned. All told me that the drivers were already up to date but I re-installed anyway. It made no difference to the unknown device.
Ok here's what happens, just bought this HD300 and it's not recognized by my 2 computers. Installed monkey, drivers, and it installs as unknown device. If I go in the driver properties, I see Mbox instead of Line 6 Pod hd300. I manually switch it to the correct one and it's still not detected by monkey or hd300 edit.Ok here's what happens, just bought this HD300 and it's not recognized by my 2 computers.

Pod HD300 Firmware 1.10 Connecting through USB to 2 different computer with Windows 8 64-bit, latest drivers and monkey. Not recognized. Driver is being installed as Unknown Device. If I go check the properties, it says the unknown device has the driver of a Digidesign Mbox. When manually changing the driver, it doesn't go through. Tried reverting to previous drivers and monkey, still not detected in Monkey. This is on both computers.
this issue overall , is either a driver installation issue... a bad usb cable, or an issue of trying a more agreeable port on your machine... (rear instead of front, or usb2, instead of usb3 for examples)
If you have an unknown device, then the driver install should work. If, however, you don't have an unknown device, find the Sound, Video and Game Controllers device that is your HD. (If there's not one, you have a problem with USB connectivity that software cannot fix. At the least, I'd start with a flash restore on the HD, but that's a different problem.)
Once you have the device located, check its device properties in Device Manager (1). You should be able to confirm the Hardware Ids (2). The Plug and Play (PnP) ID that contains VID_0E41 confirms that this is the Line 6 device. Assuming there's an incorrect driver associated with the device, it's probably because the HD was plugged in *before* the Line6 drivers were installed, and another driver matched on compatible IDs (3). The best solution is to uninstall that driver, and remove it from the system (4). You may have to reboot and repeat this process several times until you have your HD appearing as an unknown device. (Keep it plugged in to the USB port through this process.) Once that happens, unplug it from your PC, and follow the instructions to install the Line6 drivers. Then, they will be the best match found when you plug the device in.
Hi...my name is Mike and I own the POD HD 300.I recently got a new laptop and installed the latest 300 Edit software.When I hook up everything,the No Device Connected prompt shows up on the edit program.I have uninstalled the software,re-installed software,rebooted computer,changed USB ports and USB cables.Still nothing.
I am running Windows 8.Any knowledge would be greatly appreciated.Thanks!
hey Zap....I just downloaded the latest edit software and Monkey...then I went through Monkey to check drivers.Downloaded latest driver onto computer,but for some reason,computer won't enable it when HD 300 mis plugged in.I'm at a loss....your tag says uber guru/Line 6 expert...any wisdom you can give me?I really wanna get this issue fixed.Thanks...
here's the thing about Monkey...I used(or tried to) it to update driver on my HD 300.When it is connecting to the Line 6 site,it only gives the option for POD XT...apparently my 300 is just lying there...sorry to be a pain,but I'm a tad frustrated.I'll try what you said arislaf....thanks.
Have your device (pod or whatever) unplugged then go to your Device Manager. Plug in the pod. You should see a new device pop up under the "Other devices" tab... and it should be labeled simply as "Unknown". This is your pod. Right click it and choose "Update Driver Software". Choose to browse your computer for the driver software. I had trouble with Windows 8 finding the driver even if I pointed it directly to the correct folder ("C:\Program Files (x86)\Line6\Tools\Driver Archive\POD HD 300" for me.) So I chose the "Let me pick from a list of device drivers on my computer" option below that.
I then searched in the "Sound, video and game controllers" option for the hardware type, which brought up "Line 6" as a manufacturer option on the next page. I then selected that and my appropriate driver (Pod HD300 for me.) Windows briefly complained about unrecognized certificates or some such, at which point I said continue anyways. A driver installing progress bar then started. Strangely enough the progress bar seemed to get stuck (which shouldn't happen, this driver is small and should install pretty fast), but I let it run for about 5 minutes and then killed the process from task manager (just trying to exit the window doesn't work because Windows complains about you stopping a driver install before it's done... as it rightfully should, but the Line 6 software/drivers are just so buggy and hard to get going I had to go to drastic measures.) After that it seemed fine; when I relaunch device manager the pod shows up as a recognized device under "Sound, video and game controllers."
These instructions are what I did on Windows 8.1, but they should be valid for Windows 7 as well. I'm not sure about Vista, perhaps. Also note that the last step is pretty sketchy... so standard disclaimer: I'm not guaranteeing it will work on your own personal system, or even leave the system in tact, this is just what I had to do on my own computer.
Tonight I took my POD from it's box after a couple of weeks of rest. I was a bit surprised when it no longer worked as an audio interface. To be more precise, it no longer manages to communicate with any computer in any way. I'm a computer person in general and after a few hours of trying all sorts of things I am out of ideas. It seems the POD can turn into a brick at random. It is sending "usb/unknown" as its device id, so it won't accept any audio driver manually. Win7 thinks it's a USB controller so it will only let me choose from USB controller drivers and manually pointing at the .inf file fails to work. Using it on other computers confirms that it doesn't identify itself as a POD anymore. They all think it's an unknown USB controller.
Has anybody come up with another way to return the POD to its original state, where the OS can recognize it? Can't do a factory reset, since the computer cannot communicate with it at all. Any help would be much appreciated, I already tried all the USB ports, tried removing the USB hubs and adding some more. And I did nothing at all to bring this about. I just turned the damn thing on. I am using firmware v1.1 and apparently USB firmware 0.0. I was trying to upgrade to 1.2 when this happened. I mean, I never got that far. Noticed this when Monkey couldn't see the POD.
Just do a midi dump from the pedal board itself. You don't need any midi software open on your computer, just make sure your computer is on and the pod hd300 is turned on and plugged into a usb port on your computer. Follow the instructions, that are in the manual, on how to do a midi dump -"ALL". You may need to power-cycle the pod and reboot your computer afterwards, but I've found that this does the trick every time.
Why this works: Honestly, since I don't work for Line 6, or have the schematics or any design information on the product I can't be 100% sure. My best guess would be that since the pods connect to, and exchange data with, the computer via midi-over-usb, there is a voltage-high(or low) situation with the eeprom. Kind of like when old analog telephones would act like they were busy when they weren't. There is the "on-hook" voltage(3v I think) that drops when you pick up the receiver. That change in voltage is the signal to the phone company's switch that signals that the phone is in use. When you hang up the phone, the voltage goes back up. If the voltage gets stuck low, then it looks like the phone is always busy. The only way to fix that was to disconnect the exterior test jack or incoming lines, temporarily, to reset the voltage. Doing a midi dump on the pod hd300 acts much the same as disconnecting and reconnecting the exterior phone lines.
