I wanted to cross-connect the serial ports of my armv7 and riscv64
machines. Problem on riscv64: no uftdi driver. It looks like a lot of
other USB drivers are missing in GENERIC, both generic drivers and
hw-specific drivers: umodem, ugen, ulpt, uvideo, umb, uplcom etc.
Feels like it would make sense to sync those devices from arm64/GENERIC
instead of adding only what I need. Thoughts?
One glitch: usbdevs(8) isn't usable since usb(4) isn't wired in conf.c.
With the diffbelow I can use usbdevs(8) on my hifive. ok for the
usb.h/cdev_usb_init addition?
