Sorry, that was a user error (mine), I had been using the generic
usb-serial.ko driver instead of the FTDI specific one. Now it indeed
works like a charm.

Thanks, I applied the patch even though the old values worked ok too.
If they were better for some reason please tell. I also added a
chr_close callback for -serial stdio so that I can do usb_add
serial::stdio, then usb_del and usb_add serial::stdio again without
getting an error on opening "stdio".
