Should make it easier for the usb coders to debug.

I didn't have the same problem with FreeBSD 4.1, and I'm almost certain it did not occur with 4.2, but I might have had the joystick unplugged when I was using 4.2. FF devices probably report more information or do so differently than other devices. Some of them also auto-calibrate and things like that which might either slow things down or maybe they announce their presence on the bus twice or something. Did you notice, before the crash, that the kernel had some trouble querying the offending device? That happens with me, and then a little while later in the boot it crashes. -- "Secrecy is the beginning of tyranny." -- Unknown To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
