With the virtual/libusb migration, net-misc/dahdi-tools should now depend on virtual/libusb:0 if possible. See tracker bug 270039 for more information.
If you have hardware to test, please proceed with this bug. My DAHDI hardware is PCI-based (TDM400 & TDM410).
I've no hardware to test. I opened this bug for the tracker only. I think there is no problem to let this bug open until someone test it.
