This fixes a problem with the Olimex MSP430-JTAG-TINY v1, reported by Hardy Griech on mspgcc-users.
This was causing the olimex-v1 driver to fail with raw USB access.
Timeouts have been increased to 30 seconds. Reset is not sent until after enabling power.
The "olimex" transport has been divided into "cp210x" and "cdc_acm", each of which take a specific vendor/product combination in their constructor. Support for the MSP430-JTAG-ISO-MK2 has been moved into its own driver instance.
