Re: HEADSUP usb2/usb4bsd to become default in GENERIC

 Hello.

I have tried to test USB2 stack with usb flash on FreeBSD-CURRENT
under VMWare Server, but I have got dmesg output like this.

With old USB stack all works fine. There is dmesg output.

How could I track down this problem of USB2 stack?

Thanks.
