 Posted: Wed Apr 21, 2004 11:16 am Post subject: A7N8X Deluxe, Kernel 2.6.5 and USB is *VERY* slow |
 |
|
Hi all.
I've spent hours and hours going through posts and trying suggestions from here, USENET and nforcershq but I am still having major problems.
I have an ASUS A7N8X Deluxe Rev 2 motherboard with an Athlon XP 2800+, 512MB Corsair TwinX 3200LL memory and a WD 40GB IDE HDD. I am trying to use a WD external USB2 120GB hard disk as a backup device.
I have installed and configured kernel 2.6.5 from gentoo-sources. Nvidia's GLX, kernel stuff etc is loaded. I've also tried it with 2.6.5-mm6.
I can mount the disk, list files etc etc. However, I assume it's running over standard USB. hdparm reports transfers of about 2MB per sec. Each time I go to copy a file from the disk, it takes a few seconds for the light to come on and then I get about 5-10 seconds of sustained transfer (the light goes on) then it stops for a while, then flickers back and forth. I've tried the disk on another system running 2.6.3 and it is fine.
I've tried compiling in USB support, using modules etc etc. I am currently trying to use OHCI-HCD compiled in with EHCI-HCD as a module.
Can somebody please advise me on what is the best way to get USB2 working at proper full speed. Do I compile it all in and set some cryptic option somewhere? Both as modules, in a certain order? Surely there must be a recommended way of setting this up?!
PLEASE HELP! This is driving me nuts!
TIA.

DraconianTimes,
EHCI-HCD is your USB 2.0 driver. Use lsmod to see if its loaded and modprobe to load it.
If you need USB 1.1 for some things and USB 2.0 for others, they must be on seperate root hubs. Each root hub drives a pair of USB connectors on the motherboard.
If you don't need USB 1.1 at all, take OHCI-HCD out of the kernel while you play. All 3 root hubs (6 USB ports) can do USB2.0 or USB 1.1 but not both at the same time.

Thanks for your suggestions. I'll try them out tomorrow and get back to you!

NeddySeagoon,
I have tried loading only the ehci-hcd module on its own. I recompiled, ensured that the modules was loaded with lsmod and then ran hdparm -t /dev/sda1
| Code: |
/dev/sda1:
Timing buffered disk reads: 32 MB in 18.92 seconds = 1.69 MB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 32 MB in 23.91 seconds = 1.34 MB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 12 MB in 3.03 seconds = 3.96 MB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 32 MB in 21.97 seconds = 1.46 MB/sec
|
I'll recompile with ohci only and see what the results are...

And with ohci-hcd loaded only, I get the following results:
| Code: |
/dev/sda1:
Timing buffered disk reads: 2 MB in 5.92 seconds = 346.12 kB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 4 MB in 3.97 seconds = 1.01 MB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 4 MB in 3.99 seconds = 1.00 MB/sec
bash-2.05b# hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 4 MB in 3.99 seconds = 1.00 MB/sec

DraconianTimes,
Thats really dire!
emerge usbview and see what it has to say about your disc device.

Hi there.
I've tried 2.6.5-mm6, 2.6.5-gentoo and and 2.6.6_rc1 - No joy whatsoever. Is there a special order in which I should be loading the modules? Can you confirm if ohci-hcd and ehci-hcd are the rights ones? I've emerged the usbview tool, plus also here is the output of 'lsusb -v'.
Many thanks for your help!

What's the output of "hdparm /dev/sda1" ?

The output is as follows:
| Code: |
bash-2.05b# hdparm /dev/sda1
/dev/sda1:
readonly = 0 (off)
geometry = 14593/255/63, sectors = 234436482, start = 63

DraconianTimes,
Your USB hubs seem to be doing USB 1.1 rather than USB 2.0.
The drivers you need are ehci-hcd for usb 2.0 and ohci-hcd for usb 1.1. The kernel will load ohci-hcd for you if you are not careful. Do you have it in /etc/modules.autoload ?
Traverse the /lib/modules/<kernel_version>/... tree and rename the ohci-hcd module so it can't possibly load, now manually load ehci-hcd. What does that do?
Your drive says it does firewire - have you tried that?
===========edit===========
Have a peek in your BIOS, you can set USB options there for USB 1.1, USB 1.1+2.0. If you have 1.1 set ...

i have the same mobo as you do and i also use an external drive with usb2.0 hdparm shows:
| Code: |
/dev/sda:
Timing buffer-cache reads: 1924 MB in 2.00 seconds = 960.71 MB/sec
Timing buffered disk reads: 62 MB in 3.05 seconds = 20.32 MB/sec
|
which seems to be okay i am currently useing the latest love-sources
2.6.6-rc2-love1 perhaps the usb section of my kernel .config can help you find the problem
| Code: | #

#

# CONFIG_USB_DEBUG is not set
#
# Miscellaneous USB options
#

I too have an nForce 2 board (SL-75FRN2-L) and as I don't use any USB devices atm, I get about 55.81MB/sec
Once I get on my machine, when it finishes recompileing the kernel, I'll post in my config for you all, and also how I have my end setup 
Might even suggest something like why not we start a seperate part of the forums here specifically for nForce 1/2 users, it could be an idea 
Cheers

OK. I think I've now tried everything. This is total misery.
I've popped a completely seperate USB2 PCI controller card into the system. Running hdparm -t /dev/sda results in the following:
| Code: |
bash-2.05b# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 32 MB in 36.21 seconds = 904.96 kB/sec
bash-2.05b# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 2 MB in 23.49 seconds = 87.17 kB/sec
bash-2.05b# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 32 MB in 44.18 seconds = 741.72 kB/sec
bash-2.05b#
|
I have tried 2.6.5-mm6 now too. I have compiled in EHCI, UHCI, OHCI and also tried them as modules too. I have tried single combinations, of OHCI only, EHCI only etc.
My /etc/modules.autoload.d/kernel-2.6 currently looks like this:
| Code: |
ohci-hcd
uhci-hcd
ehci-hcd
|
I have checked the BIOS. It is set to 1.1+2.0, so no problems there. Could somone PLEASE tell me exactly which files I should be editing modifying because I seem to be getting conflicting opnions from all over the place as to what I should be doing. Do I need to do any device aliasing???
I would seriously appreciate somone to tell me how specfically they got their USB2 working with this board and the 2.6 kernel series.
Many, Many thanks in advance.
