So I hereby confirm that with the -3 version of USBPcap (uninstall -5, reboot,
manually remove USBPcapCMD.exe from ...\extcap, install -3, reboot, manually
copy USBPcapCMD.exe from ...\USBPcap to ...\extcap) , the behaviour is the
same.

As for the call with --exctap-interfaces, this returns normally (and did return
normally with -5 too) if called from the cmd window, same thing for
USBPcapCMD.exe --extcap-interface IFNAME --extcap-config or ...--extcap-dlts,
see below, and although I never get a prompt until I hit enter, the Task
Manager does not show the USBPcapCMD.exe to continue running after any of the
commands below prints the result.

However, Process Monitor shows that the first call by Wireshark, with
--extcap-interfaces finishes properly, the second one with --extcap-interface
\\.\USBPcap3 --extcap-config as well, but the third one with --extcap-interface
\\.\USBPcap2 --extcap-config is the last one in the log, so it is the one which
makes Wireshark hang. And if you look below at the list of devices it provides
when called from the command line, you'll see tons of items which are
individual Bluetooth services (as the embedded Bluetooth controller of the
laptop is USB based). So I'd guess that the buffer for the list of devices in
Wireshark/dumpcap is not big enough?

This would explain why none of the developers has ever run to that issue. Shall
we ask the two guys who have indicated the issue at ask.wireshark.org to
provide their output of these commands?

I'll attach the log from Process Monitor filtered using "Process Name contains
USBPcapCMD" in a while.

P.
