#10 Segfault/Memory corruption if USB device inaccessible
Using libftdi.
For example if I try to use the ftdi-mpsse driver and a device exists, but permissions are insufficient, I get the following dump:
jtag> cable ftdi-mpsse 0d06:0382 ARM-USB-OCD
Initializing Olimex ARM-USB-OCD (FT2232) Cable on FTDI device 0d06:0382
Can't open ftdi device: inappropriate permissions on device!
Error: Cable initialization failed!

A quick check whether it happens with the ftdi driver - yes:
