Public bug reported:

Since USB support has been enabled in libpcap, any utility using libpcap
is now taking a huge time to load (i.e. tcpdump and wireshark).

That's because apparently libpcap usb initialization hangs waiting for
some device:

Dec  6 00:13:50 hell kernel: [ 6610.770536] usb 4-3: new low speed USB device 
using ohci_hcd and address 9
Dec  6 00:14:01 hell kernel: [ 6621.190106] usb 4-3: device not accepting 
address 9, error -110
Dec  6 00:14:01 hell kernel: [ 6621.190171] hub 4-0:1.0: unable to enumerate 
USB device on port 3

Expected behavior:
skip lagged usb devices, disable usb support when not needed, or do anything 
else you think is reasonable to make libpcap work well as ever worked for many 
years.
