Good question. The cmd line option is a tri-state:
(no command line option) -> force_rs485=-1 -> auto-detect based on product ID
force_rs485 = 0 -> never set RS485 mode (regardless of product ID)
force_rs485 = 1 -> always set RS485 mode (regardless of product ID)

The USOPTL4-4P and USOPTL4-2P USB-to-quad/dual RS-485/422 hubs use the
Moschip 7840/7820. For correct operation in RS-485, the chip must be

datasheet. This strobes the DTR
