26b3d94504SStephan AßmusThis is yet another piece of hardware support for BeOS/Dano/Zeta operating systems.
27b3d94504SStephan AßmusThis USB Storage Module (<strong>The Module</strong>) is designed to support a wide variety
28b3d94504SStephan Aßmusof standard USB mass storage devices. Those devices are: 
29b3d94504SStephan Aßmus<ul>
30b3d94504SStephan Aßmus  <li>memory (flash) keys,</li> 
31b3d94504SStephan Aßmus  <li>external HDD/CD/DVD/ZIP/Floppy drives with USB connection,</li> 
32b3d94504SStephan Aßmus  <li>digital cameras/camcorders with USBMS protocol,</li> 
33b3d94504SStephan Aßmus  <li>MP3 players,</li> 
34b3d94504SStephan Aßmus  <li>card readers,</li>
35b3d94504SStephan Aßmus  <li>Jukeboxes</li> 
36b3d94504SStephan Aßmus  <li>etc.</li>
37b3d94504SStephan Aßmus</ul> 
38b3d94504SStephan Aßmus<p>In other (more special and technical) words this Module
39b3d94504SStephan Aßmusworks with standard USB class 8 devices, both Bulk-Only and CB[I] ones,
40b3d94504SStephan Aßmuswith all standard command sets used in such devices.

112b3d94504SStephan AßmusIf you doesn't reboot from script - you
113b3d94504SStephan Aßmushave to do it manually to let The Module work with updated settings.

115b3d94504SStephan Aßmus  </ul>
116b3d94504SStephan Aßmus  <li>After system rebooted, plug in your USB device into USB slot and

118b3d94504SStephan Aßmusyou'll see some additional volumes available for mounting. Mount that
119b3d94504SStephan Aßmusone you
120b3d94504SStephan Aßmusthink is your USB mass storage and use it as usual "real" drives.</li>
121b3d94504SStephan Aßmus  <li>It is highly recommended to unmount your USB volume before
122b3d94504SStephan Aßmusunplugging device from USB slot. Some pending read/write operations can
123b3d94504SStephan Aßmusbe still active in background. If you break this process - 
124b3d94504SStephan Aßmus<font color="#cc0000"><b>YOU CAN LOOSE YOUR DATA</b></font>. Unmount
125b3d94504SStephan Aßmusit and wait until your USB volume icon is
126b3d94504SStephan Aßmusdisappeared from desktop and led on your device ( in case this led

137b3d94504SStephan Aßmus    <ul>
138b3d94504SStephan Aßmus      <li>May be. Install this software, plug your device in and
139b3d94504SStephan Aßmustry to mount it. Or look for class / subclass / protocol values
140b3d94504SStephan Aßmusin usb device description and check against the following lists.

150b3d94504SStephan Aßmus  <li>I have installed this software on R5 + USB.patches but my <strong>system

166b3d94504SStephan Aßmus      </li>
167b3d94504SStephan Aßmus      <li>You can try open "Mount" menu with "Shift" button pressed and

190b3d94504SStephan AßmusIn some circumstances those Zeta's modules can prevent this USB Support Module from correct working.
191b3d94504SStephan AßmusIn this situation you have to disable Zeta's USB Storage support. To do this go to
192b3d94504SStephan Aßmus/boot/beos/system/add-ons/kernel/busses/scsi/ diectory and rename or remove the
193b3d94504SStephan Aßmus<strong>usb</strong> and <strong>usb_scsi</strong> files. After rebooting your system
194b3d94504SStephan Aßmusyou should have updated USB Storage support.

237b3d94504SStephan AßmusIt's reproducible with Adaptec SCSI controllers installed on your
