I'm on Win-10 and have now troubles sniffing on anything except
BlueTooth! This is the list of interfaces I expect to get:

dumpcap.exe -D
  1. \Device\NPF_{C25DD2C2-2E05-4337-A847-84EF6CAB86BF} (Bluetooth-nettverkstilkobling)
  2. \Device\NPF_{F92984E3-5D40-4AD9-B054-41288EAE699F} (Wi-Fi 2)
  3. \Device\NPF_{3A46ACA0-CBED-44BC-A239-6AEA3D0C451D} (Ethernet)
  4. \\.\airpcap00 (AirPcap USB wireless capture adapter nr. 00)

But with "tshark.exe -D", I only get:
  1. \Device\NPF_{C25DD2C2-2E05-4337-A847-84EF6CAB86BF} (Bluetooth-nettverkstilkobling)

I also tried with:
  set G_MESSAGES_DEBUG=all   << no effect
  tshark.exe -o console.log.level:252 -D

giving:
  Capture-Message: Capture Interface List ...
  (tshark.exe:8440): Capture-DEBUG: sync_interface_list_open

  (tshark.exe:8440): Capture-DEBUG:   argv[0]: F:\mingw32\src\inet\Wireshark\dumpcap.exe

  1. \Device\NPF_{C25DD2C2-2E05-4337-A847-84EF6CAB86BF} (Bluetooth-nettverkstilkobling)

Note, this is with Wireshark compiled from Git by myself using MSVC-2015, 32-bit;
A version + build-method that has worked well for years. But recently it's been
misbehaving as shown above. Any hints?

The above "read 21 indicator: S empty value" for me indicates a problem in
the pipe I/O between tshark and dumpcap. No?
