>Description:
I have Brother dcp-385c printer with USB mass storage support. I guess my 
pendrive plugged to the printer is connecting to my PC via USB 1.0 which is 
probably corresponding with ohci interface (sorry for lack of knowledge). 5.1 
fully supports this kind of connection, but 5.99 not.
As I said, I don't know much about this problem - I only know it occurs:) 

Output of dmesg shows up something like:
handing blah blah EHCI blah full speed blah OHCI blah
and
device problem disabling port blah
Repluging Printer to other ports does not change anything
The same pendrive plugged directly to my PC works as expected.
I doesn't matter if I boot netbsd with or without my printer switched on.

I work on 5.1 now so I can't paste problematic dmesg. I remeber only these 2 
lines described above, but I will read my 5.99 dmesg again later.

>How-To-Repeat:
On 5.99.56 plug in pendrive to Brother dcp-385c printer
