fteeprom-{erase,prog}: detach logic: change to detach by default As it turns out, detaching all ttyUSB interfaces of a multichannel device does not require outside knowledge of how many channels there are, as in our previous -d option design that is being removed here - instead we can read the bNumInterfaces constant from the USB device's config descriptor and thus know how many interfaces there are in total. Based on this discovery, change the design of fteeprom-{erase,prog} as follows: * remove -d option; * flip the default to where we detach all interfaces by default; * add -n option to NOT detach any interfaces.

# This CP2102 baud rate table is the version that is needed for talking
# to 13 MHz GSM devices (16x UART clock input) faster than 115200 bps:
# standard baud rates 230400/460800/921600 have been replaced with
# GSM-specific (13 MHz based) 203125/406250/812500.
