 Hi Lennart,
 
 since I see the "cannot open interrupt pipe" here on quite a few prac 
 machines with netbsd-2:
 
 ehci0 at pci0 dev 29 function 7: Intel 82801DB/DBM USB EHCI 
 Controller (rev. 0x02)
 ehci0: interrupting at irq 10
 ehci0: EHCI version 1.0
 ehci0: companion controllers, 2 ports each: uhci0 uhci1 uhci2
 usb3 at ehci0: USB revision 2.0
 uhub3 at usb3
 uhub3: Intel EHCI root hub, class 9/0, rev 2.00/1.00, addr 1
 uhub3: 6 ports with 6 removable, self powered
 
 [...]
 
 uhub4 at uhub3 port 6
 uhub4: Generic USB Embedded Hub, class 9/0, rev 2.00/0.01, addr 2
 uhub4: 1 port with 0 removable, self powered
 uhub4: cannot open interrupt pipe
 
 -- could you please request a pull-up of the changes that fix the 
 problem to netbsd-2? (Don't know if they are relevant to netbsd-1-6?)
 
 Thanks,
 	hauke
