Hi There,

(background)
I had a running FC3 based mythtv for months. Started fiddling and broke it. Am now reinstalling using KnoppMyth.
(/background)

After the reinstall, the external USB drive ran very slow - I'm getting about 1MB/s. I know the EPIA mobo is usb 2.0, as is the drive (new Seagate 400GB external). With FC3 I got 20-22 MB/s, which is just fine for Myth.

Checking /proc/bus/usb/devices, I see the controllers are listed as
Product=VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller

I see in modules that KnoppMyth is using the uhci-hcd Host Controller.
I see that ohci-hcd controller is also loaded.

I have tried switching the disk around the 4 usb ports - watching the logs I can see that in all cases, it is reported as attaching to a 1.1 controller.

Does anyone have experience with this?
Can I switch to another host controller - perhaps one that understands the via controllers are actually 2.0 rather than 1.1

Many thanks for any advice or hints you can provide.
Paul.

It appears this may be an issue with 2.6.11:
See: lkml.

lspci reports:
USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1
Controller (rev 80) (prog-if 00 [UHCI])
Subsystem: VIA Technologies, Inc.: Unknown device aa01

Nuts!
Anyone else out there running R5A15.1 and an EPIA/VIA mobo?

Regards.
Palu.

The device supports both usb2 and firewire.
So I plugged it into the firewire port and voila!

Now hdparm -t reports 27 MB/s.

Cheers.
Paul
