13	OVERVIEW
14	
15	This README will address issues regarding how to configure the kernel
16	to access a RIO 500 mp3 player.  
17	Before I explain how to use this to access the Rio500 please be warned:
18	
19	W A R N I N G:
20	--------------
21	
22	Please note that this software is still under development.  The authors
23	are in no way responsible for any damage that may occur, no matter how
24	inconsequential.
25	
26	It seems that the Rio has a problem when sending .mp3 with low batteries.
27	I suggest when the batteries are low and you want to transfer stuff that you
28	replace it with a fresh one. In my case, what happened is I lost two 16kb
29	blocks (they are no longer usable to store information to it). But I don't
30	know if that's normal or not; it could simply be a problem with the flash 
31	memory.
32	
33	In an extreme case, I left my Rio playing overnight and the batteries wore 
34	down to nothing and appear to have corrupted the flash memory. My RIO 
35	needed to be replaced as a result.  Diamond tech support is aware of the 
36	problem.  Do NOT allow your batteries to wear down to nothing before 
37	changing them.  It appears RIO 500 firmware does not handle low battery 
38	power well at all. 
39	
40	On systems with OHCI controllers, the kernel OHCI code appears to have 
41	power on problems with some chipsets.  If you are having problems 
42	connecting to your RIO 500, try turning it on first and then plugging it 
43	into the USB cable.

45	Contact information:
46	--------------------
47	
48	   The main page for the project is hosted at sourceforge.net in the following
49	   URL: <http://rio500.sourceforge.net>. You can also go to the project's
50	   sourceforge home page at: <http://sourceforge.net/projects/rio500/>.
51	   There is also a mailing list: rio500-users@lists.sourceforge.net

53	Authors:
54	-------
55	
56	Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith 
57	Clayton <kclayton@jps.net> is incharge of the PPC port and making sure
58	things work there. Bruce Tenison <btenison@dibbs.net> is adding support
59	for .fon files and also does testing. The program will mostly sure be
60	re-written and Pete Ikusz along with the rest will re-design it. I would
61	also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use 
62	with some important information regarding the communication with the Rio.

67	
68	
69	REQUIREMENTS
70	
71	A host with a USB port.  Ideally, either a UHCI (Intel) or OHCI
72	(Compaq and others) hardware port should work.
73	
74	A Linux development kernel (2.3.x) with USB support enabled or a
75	backported version to linux-2.2.x.  See http://www.linux-usb.org for
76	more information on accomplishing this.
77	
78	A Linux kernel with RIO 500 support enabled.
79	
80	'lspci' which is only needed to determine the type of USB hardware
81	available in your machine.
82	
83	CONFIGURATION
84	
85	Using `lspci -v`, determine the type of USB hardware available.
86	
87	  If you see something like:
88	
89	    USB Controller: ......
90	    Flags: .....
91	    I/O ports at ....
92	
93	  Then you have a UHCI based controller.
94	
95	  If you see something like:
96	
97	     USB Controller: .....
98	     Flags: ....
99	     Memory at .....
100	
101	  Then you have a OHCI based controller.
102	
103	Using `make menuconfig` or your preferred method for configuring the
104	kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
105	hardware (determined from the steps above), 'USB Diamond Rio500 support', and
106	'Preliminary USB device filesystem'.  Compile and install the modules
107	(you may need to execute `depmod -a` to update the module
108	dependencies).
109	
110	Add a device for the USB rio500:
111	  `mknod /dev/usb/rio500 c 180 64`
112	
113	Set appropriate permissions for /dev/usb/rio500 (don't forget about
114	group and world permissions).  Both read and write permissions are
115	required for proper operation.
116	
117	Load the appropriate modules (if compiled as modules):
118	
119	  OHCI:
120	    modprobe usbcore
121	    modprobe usb-ohci
122	    modprobe rio500
123	
124	  UHCI:
125	    modprobe usbcore
126	    modprobe usb-uhci  (or uhci)
127	    modprobe rio500
128	
129	That's it.  The Rio500 Utils at: http://rio500.sourceforge.net should
130	be able to access the rio500.
131	
132	BUGS
133	
134	If you encounter any problems feel free to drop me an email.
