Hi all,

I have noticed something rather strange/disappointing in NetBSD v3 
(depending on whether it is easily resolved or not)...

I have an iBook G4 and am regularly copying some files to/from USB storage 
device (i.e. usb SD card reader via umass under NetBSD).

The problem is that exactly the same hardware configuration (i.e. using the 
same iBook and the same SD card reader) under OSX (Panther) OR Linux (kernel 
2.6, Gentoo distribution) results in files being copied to/from USB storage 
device enormously faster (i.e. so much so that even without any 
specific/succinct benchmarking it is obvious that OSX/Linux powered 
configurations read/write USB storage device multiple times faster than 
NetBsd).

My NetBsd is version 3, generic kernel and from what I can tell it detects 
plugged-in USB device as being attached to a USB1 (which is much slower than 
USB2 of course) bus and consequently all of the data communication is done 
at the USB1 speed... but I think that the hardware (i.e. iBook G4) has USB2 
ports AND it does not make sense otherwise to see SO MUCH difference when 
using the same hardware under OSX or Linux (both OSX and Linux 2.6/Gentoo 
were NOT tweaked in any way from their "default" installation state to 
achieve any extra speed up when dealing with reading/writing of USB storage 
devices).

My question (which is followed by dmesg and usbdevs -d -v output) is: "is 
there any setting/utility either at runtime or via modification of kernel's 
makefile [but not via some patch to sources] and then rebuilding the 
kernel)?"

By the way - I think this problem is not just related to iBook hardware - 
from my (albeit non-robust) memory I recall having the same issues (i.e. 
other OSes [Windows/Linux] copying files MUCH MUCH faster than NetBSD) with 
Celeron-based laptop and AMD desktop machine... so there... :-) Any advice 
will be greatly appreciated...

Kind regards,
Leon.
