FW: [linux-usb] D-Link DSB-500 Adapter probs

Hi,

A Linux USB user reported this PCI IRQ assignment
problem.  Martin Mares suggested that I send this
to you.

Any suggestions or fixes that you can recommend?

Thanks,
Randy

I/O space on the UHCI controller is not enabled.
See below.

Hi Martin-  Any ideas/suggestions about this?

From: Peter R. Wood [mailto:pwood@gordon.edu]

Hello,

I am having troubles with a D-Link DSB-500 USB adapter card,
specifically
with using a Diamond Rio 500. I'm emailing these lists on the
suggestion
of Keith Clayton from the rio500-linux team.

I have a UMAX SuperMac J700/1800 (PowerMac clone) with a PCI
bus, and a
fairly standard PowerMac motherboard.  I am currently running LinuxPPC
2000, with kernel 2.2.16 downloaded from ftp.kernel.org, and the USB
2.3.99 to 2.2.14+ backport patched in. I have compiled the kernel with
usbcore, usb-uhci (not the alternate uhci), and rio500 modules.

My problem comes when I try to connect to my Rio using the
rio500 utils. I
first try rio_format, but I get the message:

---
Could not open /dev/usb/rio500: Device or resource busy

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I haven't figured out the root source/cause of this, but
the problem is below.

Verify that the rio module is loadad and your Rio is
connected and powered up.
---
I've verified that I have the correct node created for the rio in
/dev/usb:

crw-rw-rw-    1 root     root     180,  64 Jun 11 01:25
/dev/usb/rio500

Here are some informational messages from the kernel, and
from lspci -v:

in dmesg, the kernel reports the following when I load the modules:

usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.228 $ time 01:46:10 Jun 11 2000
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: USB UHCI at I/O 0x1000, IRQ 1
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 1
usb-uhci.c: USBCMD_HCRESET timed out!  ********************************[1]
usb.c: USB new device connect, assigned device number 1
hub.c: USB hub found
hub.c: 2 ports detected
usb.c: registered new driver rio500
rio500.c: USB Rio support registered.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[1] This shouldn't happen.

lspci -vv tells me about the controller:

01:00.0 USB Controller: VIA Technologies, Inc. VT82C586B USB (rev
04) (prog-if 00 [UHCI])
	Subsystem: Unknown device 0925:1234
	Control: I/O- Mem- BusMaster+ SpecCycle- MemWINV+ VGASnoop-

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I/O- means that I/O space is not enabled in the Command register.
My system shows "I/O+".
Also see 6 (of lspci) lines below where it says "[disabled]".

This is a problem with PCI resource assignment.

ParErr- Stepping+ SERR- FastB2B-
	Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR+ <PERR-
	Latency: 32, cache line size 08
	Interrupt: pin A routed to IRQ 1
	Region 4: I/O ports at 1000 [disabled]

I am unfortunately unable to test whether this card works under MacOS
since I do not have access to a new enough version of the
MacOS. I know
that the Rio is working fine, since I connected to it using its
including cable on another Mac (B&W G3 w/built in USB) via
MacOS and the
RioPort software. I was able to get the status and send some
mp3 files to it.

If anyone has suggestions, I'd be grateful. Let me know if there's any
other information about my setup (hardware/software) that I could give
you.
