(Un)ignore USB devices

Submitted by Nano on #1

Hello,

I have selected to ignore two USB devices on my Raspi with the Windows client.
Now I would like "un-ignore" them. What is the correct way of doing so?

I have stopped the daemon and manually edited the file /root/config.ini and removed everything from the option "IgnoredDevices".
Strange: the option "IgnoredDevices" only shows one ignored device and not both devices. However, the second missing device is also not listed anymore. It is completely gone from VH-client. I have not tried to reboot yet.

Any idea what's going wrong here?
The now completely missing USB device is a Huawei 3G modem, a USB composite device.
However, it is still working normally as 3G modem on the Raspi.

Cheers,
Christian

Yes there is no way in the GUI at the moment to unignore devices. To do this edit the c:\Users\your username\AppData\Roaming\vhui.ini and remove the IgnoredDevices entry in there (under windows) and under osx , /Users/your username/Library/Preferences/vhui Preferences.

Update:

I have rebooted the Raspi and the desktop PC several times with cleaned option "IgnoredDevices".
No chance. The 3G modem is gone from VH client. However, it is working properly on the Raspi.

Also the other USB device which was the only listed ignored device does not show up with the proper name anymore.
It only shows the PID as the name.

So, there seems to be a bug somewhere in VH.

What I do not understand is why a reboot does not help?
Are there any other files that VH uses to store meta data on the server?
Or is it the VH client in Windows which stores additional info in the registry?

Ok, thanks. That was the missing link: c:\Users\your username\AppData\Roaming\vhui.ini

The only thing left is the USB device which only shows 0xec00 as device name in the vh client.

I have just learned that 0424:ec00 is the USB fast ethernet adapter which is included in the USB hub chip.
(SMSC9512/9514 Fast Ethernet Adapter)

This device enumerates as being vendor specific.

Any chance the VH server/client shows this as the Rasp USB ethernet adapter properly?

Yes it's the pi Ethernet chip ,the reason it shows a code and not a name is because the device does not contain a USB string descriptor for the name of the device. Linux figures out its name from USB.ids file. I don't use that file because it has confusing entries for some devices, particularly USB drives.

By-the-way don't share the Ethernet adapter via virtualhere otherwise you will lose you network connection until the pi is hard reset, hence that is why it is ignored by default
