To:
The FreeBSD Developers Family,

First of all let me thank you for the wonderful work that you are doing.
I am a student of Computer Science doing my Bachelor in Computer Science.
I am pretty new to the FreeBSD revolution, and hence am best described
as a total newbie. I have installed FreeBSD 5.0 that I got with a book.
My digital camera supports the UMASS mode and produces the
following error when connected to the USB port.

> umass0: Residue incorrect, was 0, should've been 512

I am aware that you have already addressed the bug (kern/52383)
But I am unable to fix the bug as per the guidelines given in the
report.

I have tried to recompile the kernel with the following changes in the
files and regenerated the headers as stated in "usbdevs":

        /usr/src/sys/dev/usb/umass.c
> { USB_VENDOR_NIKON, USB_PRODUCT_NIKON_DSC_E2000, RID_WILDCARD,
> UMASS_PROTO_ATAPI | UMASS_PROTO_BBB,
> IGNORE_RESIDUE
> },

        /usr/src/sys/dev/usb/usbdevs
> product NIKON DSC_E2000 0x8888 Digital Camera E2000

I suspect that I am somehow not getting the product name correct and
hence FreeBSD does not recognise the camera as the device stated above.
Please can you guide me? I will be grateful to you for any help.
Can you also please provide a valid hex number to be assigned to
the above-mentioned product? The camera is Nikon's "CoolPix 2000".

If I am supposed to send in more information, please let me know,
I shall be glad to be of use to the team. Should I upgrade to the
5.1 current version to solve this problem? Is there any way to use
the command line interface to ignore the residue since many such
products may cause FreeBSD to cough out errors and it may not be
practical to wait for adding quirks for every such device.

Another query - is it possible to drop the USB support from the kernel
and just compile the usb.ko and experiment with the code? I tried to
comment-out the USB support but FreeBSD seems to ignore that. When I
try to "kldload usb.ko" I get the message that the
"kldload: can't load usb.ko: File exists".

Or is it possible to compile only that part of the kernel which is changed
to bring the compilation time from 1 hour to a little lower? (My processor
is 333MHz Pentium II.)

Best of Luck for all your undertakings!

With regards and admiration,
