I have now tested this using -current sources from 2013.09.12.07.26.13.
With the unmodified -current soruces (without your patch), I got
"uhub2: device problem, disabling port 2" in 4 boots out of 10.
With your patch, I got "uhub2: device problem, disabling port 2"
in 5 boots out of 10. In other words, the patch made no statistically
Here is a diff between the relevant parts of the dmesg output from a
successful boot and an unsuccessful one:
< uhidev0 at uhub2 port 2 configuration 1 interface 0
< uhidev0: Belkin Components USB-PS2 Adapter, rev 1.10/1.20, addr 3, iclass
< ukbd0 at uhidev0: 8 modifier keys, 6 key codes
< wskbd0 at ukbd0: console keyboard, using wsdisplay0
< uhidev1 at uhub2 port 2 configuration 1 interface 1
< uhidev1: Belkin Components USB-PS2 Adapter, rev 1.10/1.20, addr 3, iclass
< ums0 at uhidev1: 5 buttons and Z dir
< wsmouse0 at ums0 mux 0
> uhub2: device problem, disabling port 2
Thank you for looking into this, and if there are any more tests I can
run, I will be happy to do so.
