 It is an Intel ehci(4) chip:
 
 pchb0: Intel E7230 Host (rev. 0xc0)
 [...]
 ehci0 at pci0 dev 29 function 7: Intel 82801GB/GR USB EHCI Controller (rev. 
0x01
 )
 ehci0: interrupting at ioapic0 pin 23
 ehci0: BIOS refuses to give up ownership, using force
 ehci0: EHCI version 1.0
 ehci0: companion controllers, 2 ports each: uhci0 uhci1 uhci2 uhci3
 usb4 at ehci0: USB revision 2.0
 
 The problem is probably related to this:

 http://releng.netbsd.org/cgi-bin/req-5.cgi?show=1158
 
 I've not seen the problem for a long time.
 
        Kind regards
