Long delay opening tshark on CentOS 7
An strace shows tshark timing out on this one interface. It doesn't matter which interface I am actually trying to capture on. I do not ever use the USB interfaces. TShark 1.10.14
8171 09:24:34 open("/dev/bus/usb/001/003", O_RDWR) = 6
8171 09:24:34 ioctl(6, USBDEVFS_CONTROL, 0x7ffe3d482280) = -1 ETIMEDOUT (Connection timed out)
8171 09:24:39 close(6) = 0
This happens in the middle of all interfaces being enumerated. The problematic usb interface is associated with the virtual IPMI presence. Is it necessary to query the unused interfaces?

UPDATE: It didn't occur to me that a fully updated CentOS 7 system would be on such an old Wireshark version. I will retest on newer version ASAP.
