Distribution: Debian Testing
Hardware Environment: JVC MP-XP7230FR
Software Environment: kernel
Problem Description:

During the boot, I see the following messages:

After that, USB hotplug does not work at all for USB 1.1 devices. (I have not
tested USB 2 devices). Plugging a device seems to go undetected bu the kernel.

I'm still able to mount a USB 1.1 storage device if it is plugged-in at boot time.

Steps to reproduce:

Booting on a JVC MP-XP7230 ou MP-XP7250 laptop :)

I was able to find the following patch on the web that fixes this issue for me:
http://people.freenet.de/umaxx/howto_linux-on-jvc_mp-xp7250de.txt

I'm now using a 2.6.8 kernel with this patch applied, and USB is working nicely.

Created attachment 3811 [details]
patch adding no_handshake module parameter

Looks like a BIOS bug ... when BIOS offers to handshake,
it had better be prepared to implement its part!

The attached patch should give you a module parameter
you can use to override that behavior, doing much the
same thing as that less general patch.	 Eventually
the pci quirks code should probably recognize this
board (and similar ones!) then clear that IR bit.
Comment 2 Jean-Philippe Gu 2004-10-17 06:11:28 UTC 
This patch (patch adding no_handshake module parameter) worked nicely for me,
but did not apply cleanly to kernel 2.6.8.1. I had to play with it a bit to get
it to apply.
Comment 3 David Brownell 2004-11-10 16:27:49 UTC 
closing; the module parameter should address similar issues 
in the future.
