I debugged the devusv.c usbuhci.c in /sys/src/9/pc, and got the
following result, where I'm confused why the b=0x0 value of the last line.
If this is true it would write to 0!, and system hungs.   It's very
reasonable, but why we get b=0x0 at dumptd()...

Anyway the debugging outputs after I plugined a usb disk are:

e: 95
r: 95
r2: 280
r3: 80
r: 95 0
e: 95

here stalls.

The functions used are:
  portenable()-->portreset()-->portenable()-->write()-->qxmit()-->queuetd()

I touched some on usb device long time ago, and now forgot all
because of my aging efect.

If someone point me the place reporting wrong values, please
let me know it.

control transfers may read/write 0 bytes.
That's not the issue probably.

IMHO, it's likely that at some point the driver missed a td and
from that point on the endpoint stalled.

No, I meant kernel tried to write to fd 0, not 0 byte.

Re: [9fans] usb problem of Asus P5K-VM motherboard

[Francisco J Ballesteros]

If I understood your mail, the problem is that buf is 0.
That's not always a problem for a usb td. It could be a 0-bytes transfer.
Such thing is ok.

i'm don't know very much about plan 9's usb stuff but
the motherboard claims more ports (12) than UsbMax
(10).  i wonder if that could cause some trouble.
see pc/devusb/^usbinit.

A curious poit is there are only six usb ports here.
When I plugin any USB device on this board, system hungs.

Wao, good news!

Yes, it has marvell 88... chip.   Later I'll confirm it...
I have already one Ken's fs (geof's 64bit update version), and this time
it'll be used as fossil+venti server.   The sata drives are now
being used as compatible mode (IDE), sick☺

Thanks for your reply, erick.
This motherboard has on board serial connector but not
the cable to the rear panel.   I hand-maded that's cable, and
using serial mouse.    However, serial mouse is not so good
for a large display area...

The output of pci will be reported later (I'm now in home)

sorry about the double post, but since you mention
the benefits of ken's fs and this motherboard together,
i should mention that you can use ken's fs with sata
drives if you have a hba that supports ahci, ide
emulation on sata (many do), or the marvell 88sx chipset:

could you send the output of pci?

i have some patches to the uart code that will allow you to
use a non-onboard uart as a console if you're interested.

[9fans] usb problem of Asus P5K-VM motherboard

[kokamoto]

I'm now being forced to use this motherboard with C2D 2.66GHZ for
a new fossil+venti server of my new lab with a SATA HDD and a SATA
CDROM drive.   I know this is not suitable to Plan 9, however forced to...

As you know, it has no PS/2 mouse port, but only has usb (12 ports!).
As I faced usb problem (uhci), I put a serial RS232C port to this mother
board, and using serial mouse now (not so happy though).

This machine reports only 6 usb hubs (not 8 hubs I have), why?
Anyone using this boad' usb succefull?

Thanks in advance
