So instead of "cryptsetup luksClose" use dmsetup remove for crypt device too
(There was a bug in some version of cryptsetup which failed close if underlying device
disappeared, should be fixed in >=1.1.2, anyway "dmsetup remove" is low-level equivalent.)
Also see man page and "dmsetup remove -f" flag.
The usb device reinitialization is separate problem, maybe someone can help if you provide
more logs.
