USB 2.0 problem in kernel 2.6.3

lilsirecho · 2004-03-04 05:58:54

Performed the tail -f /var/log/messages command again with the USB HDD connected to usb 2.0 port and the same message appeared.

This report indicates something is missing in the scsi support of the usb-storage device.

Any ideas? Kernel 2.6.3.....

Are they needed for USB2.0??

In addition to the missing drivers noted in last post, the following appears to be relevant to the USB 2.0 difficulty:

Google search LWN:Patch; USB Update for 2.6.3 dated Mar. 4, 2004

Does this patch address my problem with 2.0?

lilsirecho · 2004-03-05 16:05:44

Further gleanings from the net:OK, this section talks about what makes USB 2.0 tricky. And it's not all that user visible, so you can safely skip reading it if you're one of the many Linux users who just wants a top quality OS (or a Free one) and aren't very concerned about all the underlying technology. If you want to skip this, remember just this one thing: hubs with more than one TT may support more active low and full speed devices, especially more webcams or audio devices.

If you're writing a device driver, you may want to know about this, since it can affect how you write your driver. At this writing, not all transaction translator features are used by Linux. Also, since those code paths aren't used much yet, a number of shortcuts have been taken, which limit throughput. (Someone will surely provide a patch to remove those shortcuts if/when they become troublesome.)

I hope the patch is on the way....

The listing in /lib/modules/2.4.25/kernel/drivers/usb/host:

......ehci-hcd.o
...... sl811.o.
......usb-ohci.o

The listing in /lib/modules/2.6.3/kernel/drivers/usb/host

......ohci-hcd.ko

It seems there is no module to be installed for ehci-hcd.xx nor is there one for sl811.xx

This information conflicts with googling shown previously which listed ehci-hcd.ko.

If the arch kernel info is correct googling didn't help at all!!

If it is incorrect, how to fix it????

lilsirecho · 2004-03-06 01:39:25

Please excuse my error in previous post which listed the modules...it was for the wrong kernel...2.4.25 instead of kernel 2.6.3.

Kernel 2.6.3 lists ohci-hcd as a module and ehci-hcd is listed as installed by the kernel.

It is my understanding that all three ohci, uhci and ehci are required for operation at 480kb/sec with the ehci-hcd hub controller(probably under different device arrangements).

Is there a way to establish that the ehci-hcd package is indeed installed(even in the face of the kernel config listing)???

There are translations made to enable the 2.0 device to be driven at "high speed" as opposed to "Full Speed". My transfers never exceed 6mB/s in 2.0 mode.

What next? Find agent listings...probably none for my USB device!!!!

Please advise me as to what this printout means. Does it mean there is no module to drive my usb device?

Where is the file which shows the data pertinent to this printout?

New approach....attack from the other end..

Stay tuned...will have the drive checked out by SimpleTech...

Contacted vendor of USB HDD and received very poor response and absolutely no help.

Present state of the USB problem....

The transfer speed indicated in a 1GB transfer from the external drive to home directory varies with every trial.

Some of the trials give a burst at speeds over 90KB/s (indicated, probably faster) and the speed reduces insteps down to 16KB/s and holds until 600MB is reached and then it drops to 7KB/s for the remainder of the transfer.

Most trials give less than 6GB/s for the entire transfer.

Attempting to obtain a better steady state rate, I tried the pci card from Orange Micro.

It performs in a similar manner. My understanding is that it is a NEC chipset which operates with Ehci/ohci support in its hub.

The Via6202 chipset in my mobo operates with Ehci/Uhci support in its hub.

The indicated support in KDE for the usb-storage device is an Ehci device. This device can be supported by either Uhci or Ohci devices as I understand the system.

The action of the transfer devices suggests overheating of the device hardware components, probably not a true condition.

The other possibility I see is loss of bandwidth due to irq activity from another device.

Of course, I may have a poor performing HDD.

That is the status of USB 2.0 on my system with Kernel 2.6.3.

lilsirecho · 2004-03-11 05:22:13

I have just finished running the external drive as an IEEE1394 device with the same transfer test and it fails to run at high speed with that arrangement as well.

I conclude that my drive is kaput!!
