Connecting USB to a Windows 10 PC won't work

jim85iroc

I'm having trouble getting Windows to recognize the Spark via USB. I've installed the SPARK ASIO driver V4.8 (twice), and it still won't recognize the connection. In Device Manager it shows up as "Unknown USB Device (Device Descriptor Request Failed), and within the Positive Grid USB Audio Device Control Panel interface that runs on the PC, it also can't recognize any USB connection.

I've followed the Spark recommendation to remove the driver, reboot, reinstall, and was careful not to plug the USB cable in until the installer got to the "next" screen as the troubleshooting page recommended, but none of it makes a difference.

Does anybody have some advice for me to get this to work? My Katana 50 was a plug and play affair, but this sure as hell isn't.

Thanks

FYI, I got it to work. The PC wouldn't recognize the amp if I was plugged into my hub, but it worked when I connected directly to the PC.

@jim85iroc Thanks for letting us know what solved your problem!

Worth noting that once you've installed the USB drivers and your PC is on, its a USB speaker and not a bluetooth one. So if you were using the USB connection to a PC to stop the humming, you can't use any of the backing music features of the app anymore. I strapped the end of the USB lead on to a radiator instead!

This is just worked for me.

Instead of using the cable I normally use for my board, I used the cable that came with it.
Removed my previously failed device from device manager that was trying to use the Microsoft USB driver.
Unplugged USB cable from PC.
Turned spark amp off.
Ran installer for 4.80.
Plugged in USB cable on both ends.
Turned on the amp.
Launched spark console from system tray.
Verified I was connected.
Went Settings-Sounds and verified Line Spark 40 was my input device.
Plugged in my guitar and verified I was getting an input signal.
