Re: USB Camera and SCSI Mass Storage device



OK,

I've tried the suggested removal of "hdd=ide-scsi" from /etc/grub.conf.  The CDROM still functions and ALL devices have been removed from /proc/scsi/scsi.  Below is a snip of what it reads now...

Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor:          Model:                  Rev:
  Type:   <NULL>                ANSI SCSI revision: ffffffff


When attempting to mount any /dev/sdxx device, I get the familiar "not a block device" message


After returning the /etc/grub.conf back to it's original state, the cd-rom is now visable as a scsi device, but not the camera (as shown below).

in the /proc/scsi directory, there are listings for usb-storage-0 and usb-storage-1..they've always been there....


Any other ideas?

Thanks
Dan D

remove the word "hdc=ide-scsi" from /etc/grub.conf ( the line starts 
with kernel /boot....) If you are using GRUB as boot loader. (the 
default)

Maybe not.  From the position in /proc/scsi/scsi it could be /dev/sg0.  
At least it works that way wth scsi tape changer controllers

The difference between robbery and taxes is simple:   The first is 
someone threatening to hurt you if you do not give them your money.   
The second is legal.
