Did you boot with "no_console_suspend"? Are you using a VT console
instead of X (a serial console may or may not work as well)?
You might also want to #define VERBOSE_DEBUG at the start of
drivers/usb/core/driver.c, before the first #include.
Yes, I'm booting with no_console_suspend and console=ttyS0. On that
system there is no X. Multiple ttys are showing up on display with
KMS or VGA text mode (just the getty, all kernel and init output goes to
serial console as expected)
As noted in first e-mail, I disabled SERIAL_8250_PNP as that one
