 I tried to upgrade a machine running NetBSD 5.1 to 6.0_RC1 and found
 that the USB keyboard no longer worked.  A quick search of the PR
 database turned up this PR (kern/46696) describing the same
 symptoms.
 
 With 5.1, dmesg shows:
 
   uhidev0 at uhub3 port 2 configuration 1 interface 0
   uhidev0: vendor 0x1267 product 0x0103, rev 1.10/1.01, addr 3, iclass 3/1
   ukbd0 at uhidev0
   wskbd1 at ukbd0 mux 1
   wskbd1: connecting to wsdisplay0
   uhidev1 at uhub3 port 2 configuration 1 interface 1
   uhidev1: vendor 0x1267 product 0x0103, rev 1.10/1.01, addr 3, iclass 3/0
   uhidev1: 2 report ids
   uhid0 at uhidev1 reportid 1: input=2, output=0, feature=0
   uhid1 at uhidev1 reportid 2: input=1, output=0, feature=0
 
 With 6.0_RC1, there is just:
 
    uhub3: device problem, disabling port 2
 
 The machine in case has an Intel DH67CLB3 motherboard with BIOS
 version BLH6710H.86A.0131.2011.0926.1945.  I have tried two different
 keyboards, and they both work with 5.1 and fail with 6.0_RC1.
 
 IMO, this is a rather serious regression.
