[ale] usb-storage

[Chris Fowler]

Oh 
yea,  Do not unplug the CD and plug it back in while the system comes back 
on.  PANIC!

To get 
the CD to work, I have to take following steps.
<SPAN

1. 
TURN OFF the OnSpec
<SPAN

modprobe usb-storage
4. 
Turn on Onspec

Plug in USB cable.

This 
is a major pain

  I got it working on 2.4 with a CD-ROM.  But It seems like 
  Linux wil not recognize any HDD I put into the <FONT 
  size=2>box.  I'm starting to think I was ripped off.  The unit I'm 
  using is an OnSpec External IDE -> USB and is using 
  chipset 90C36.  I am getting a little scared in Linux <FONT 
  size=2>When I get error message at each load of CD device, "WARNING: Data 
  integrity not assured"Â  Do I really want to burn 
  CD's on USB?  I really wanted to use it for extra storage but it seems I 
  may be out of luck.

  I just connected an 8GB HDD to my linux box using an external 
  USB -> IDE box.  When 2.2.16-20 (RH 7.0) 
  boots, It sees my USB ports but stated that the 
  device connected is not supported by any loaded 
  driver.  I then excuted "modprobe usb-storage' 
  and the kernel message was 'USB storeage support registered'. <FONT 
  size=2>I did not see mention of the HDD.  Is 
  there a missing step?  What device nodes do I use 
  to partition and format this drive? <FONT

  usb-storage support in Linux 2.2 is there, but the 
  usb-storage maintainer actually wishes that it were 
  only in 2.4. USB mass storage uses SCSI transport and 
  requires lots of the SCSI subsystem to be in place, 
  but the Linux SCSI subsystem changed a lot between 2.2 
  and 2.4.  usb-storage is really written for Linux 
  2.4, not 2.2. 
  After that, USB->IDE controller support still may not work 
  for some controllers, even in Linux 2.4.  It is 
  still being worked on a good bit. 
  It would help to see the contents of /proc/bus/usb/devices 
  when you have this device attached.  That would 
  provide the device descriptors. 
  Some works in progress for USB IDE are: <FONT

  and <A

  plus whatever is already in the Linux 2.4 kernel.
