Schiit Eitr and Modi MB not being detected by PC

[TheTalbotHound]

My PC is not detecting either of my Modi Multibit or my Eitr. I have another external DAC and it connects to my PC with the same cable and port. When I try to reinstall the drivers on the Schiit website I get the message "please connect the cmedia USB 2.0 audio device", even though the device is connected and turned on. The device does not show up in the Device Manager. Does anyone know what I can do to fix this?

Try all USB ports? Unplug other USB devices and then just the DAC. Any luck after that?

Be sure to try another USB cable because even though it works with another drive Tyne cable may be USB 2 vs USB 3 etc.

DAC Not Recognized/Disconnecting From Computer

1. Welcome to Windows 8/10 (or Apple Mavericks/Yosemite/El Capitan/Sierra) awful "port power management." In their quest to save us from excess USB power consumption, they have caused all sorts of problems. Just Google "windows 10 USB port power management" or "yosemite USB port power management" if you don't believe us.

2. You may be able to eliminate it by disabling port power management. Maybe:

3. A definitive solution is to buy a $10-20 externally powered USB 2.0 hub and insert it between your computer and your DAC. Or use a Wyrd. This provides power that an underpowered USB port cannot.

4. If you use Windows, and are comfortable with editing the Registry (danger Will Robinson!), then the following advanced fix can eliminate the problem on Windows machines:

1. Open Device Manager.
2. Click "View" in the top bar of the open Device Manager window and select by connection type.
3. Open the tree for your USB Host Controller and find your Schiit Audio Device.
4. Once found, right click to open the Context Menu and select "Properties"
5. Click on the "Events Tab."
6. In the "Information" pane will be text that will read something like:
"Driver Management has concluded the process to add Service usbaudio for Device Instance ID USBVID_XXXX&PID_XXXX&MI_006&21084A46&0&0000"
7. The above string tells you the Vendor ID (VID), Product ID (PID), and Instance ID of your Schiit Audio Device.
8. Open the Registry Editor (regedit.exe) and navigate to "HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Enum USB"
9. Open the "USB" tree and find the VID & PID string that matches the one of your Schiit Audio Device, open this tree as well.
10. Find the Instance ID that matches your Schiit Audio Device and open that tree, then click on "Device Parameters."
11. Double Click on the "EnhancedPowerManagementEndabled" to edit the value, set this value to 0 (zero) and click OK."

I don’t recommend the registry fix as when I tried it I could no longer properly boot up.
It is much simpler to just disable it in the Control Panel.
