Hello All:
I've been following this excellent list for a while, and been able to solve most
of my problems with the patches provided. Keep up the good work.
Thanks in advance for any help anyone can offer.
I haven't yelled for help before, because I'm working with our own hardware.
I don't want to waste anyones time, chasing a software problem that doesn't exist.
And YES, I've had my share of hardware problems.
But they are all gone now, "YEH RIGHT". :-) Until the next one shows up.
Also I realize that most people don't have a system configuration, that is like mine.
So tracking problems can be difficult.
I'm open to any patches, debugging, & hardware finger pointing, that anyone wants to
provide.
I hope that I can provide some usefull information, to help fix some of the other
problems,
not only mine.
NOTE:
I've noticed in other threads, corrupt file transfer problems, with USB-2.0.
I've seen block compare errors on my system as well. Not every time, but they are
there.
I haven't tracked this, because I've been banging my head against the wall, on this
current problem.
I'll run some tests with 256mb transfers, to see what I can find.
256mb is all I can do, that is my largest part. 4mb/sec write, 6mb/sec read.
I don't use usb-storage & have seen this problem.
If anyone wants more information, or wants me to try something, unrelated to my current
problem, just ask. I'll do if I can.
Here is a problem I discovered by accident, because I was too lazy change parts, from
USB-1.1 to USB-2.0.
At first I thought I was chasing a hardware problem.
Now I'm not so sure, because I can reproduce the problem, with off the shelf hardware.
This is what I have:
System-2:
Eval-Tech 660 CPU board, Intel Celeron 900MZ, 3 PCI-USB2.0 boards (NEC upd72100)
This is a development system with off the shelf parts.
System-5:
Eval-Tech 660 CPU board, Intel Celeron 1000MZ, 3 (NEC upd72101)
This system has our own PCI board with the host controllers.
The main differances between the 72100 & 72101 are:
72100 160-pin, 72101 144-pin
72100 EHCI 0.95, 72101 EHCI 1.0
I have a pdf doc from NEC on the 72100 vs 72101. I can e-mail to anyone
that wants it.
Test parts:
12 USB 2.0 256mb flash drives
12 USB 1.1 16mb flash drives
I have narrowed this down to the most simple test that fails & which will
run on both hardware. All of the additional features of our board are disabled.
The 2 systems "in theory" :-), should be the same.
Changes to kernel modules:
I added controller info to some of the debug messages, so I know where the failures
are.
With 6 OHCI controllers, I can have 6 device numbers that are the same.
I turned off the printing of the config info.
Just too much output, with 12 devices.
********** REQUEST ***********
Would it be possible for someone to add the controller info to the debug
messages, in the proper way.
I just stuck in what I needed, without any thought as to format.
******************************
Test software:
2.4.21-pre4 kernel.
All I/O is done using libusb.
Hotplug is disabled.
usb-storage is NOT used.
All transactions to the device are done via RBC commands. (BCB, data, CSW)
The test forks 12 processes that read from 1 device.
For the 256mb parts, read 50mb, in 64k blocks.
For the 16mb parts, read 15mb, in 64k blocks.
Some of the error codes, -75 EOVERFLOW, I can' find in any of the source I'm running.
I'm probably blind!
***************************************************************************************************
Test 1:
#lsmod
Module Size Used by Not tainted
ehci-hcd 23808 0 (unused)
usb-ohci 22944 0 (unused)
usb-uhci 24260 0 (unused)
usbcore 77152 1 [ehci-hcd usb-ohci usb-uhci]
EHCI driver loaded, 256mb parts, PASSES, on both systems.

Test 2:
#lsmod
Module Size Used by Not tainted
usb-ohci 22944 0 (unused)
usb-uhci 24260 0 (unused)
usbcore 77152 1 [usb-ohci usb-uhci]
OHCI driver loaded, 256mb parts, PASSES on System-2 ONLY.
Here is some of the more interesting out from System-5:
Almost all of the failures occure on 00:12, 00:11 & 00:13 rarely failed.
Also these failures occure randomly, within the test. The block count is different.
00:12 fails, somehow every time.
--------------------------------------------------------------------------------
When this happens, I have to unload & reload the whole USB subsystem,
to get the machine back to a runable state. This only happened 2 times out of 100.
I've seen this failure on both hardware.

This is consistant with both machines. Port 2 of all the controllers fail.
This is the only reason I don't think this is a hardware problem.
