USB UHCI broken again w/ visor

USB verbose debug is ON, using driver usb-uhci, on an alpha, kernel
2.4.9, new batteries in the thing.  This worked with 2.4.7.  What
happened?  It seems like every other kernel version it gets broken
again, and I can't sync my visor.

It looks like your uhci controller is not getting interrupts anymore.
Does the value of /proc/interrupts for the usb-uhci driver get
incremented?

Does any other usb devices work on this system?

thanks,

No, it seems stuck at a non-zero value.

The non-zero value is probably because I was using another device.

> Does any other usb devices work on this system?

Yes, I have a SanDisk ImageMage (SDDR-12) that sorta-works with the
usb-storage driver.

The device times out though after transferring a few files.  I don't
know if the problem is with the usb-storage driver, usb-uhci, or the
device itself.  But this problem has existed for a long time, and OHCI
users don't report this problem.  (using usb-storage with this device
and my little program to transfer files to it:
http://www.sourceforge.net/projects/mj-tools/)  I haven't been able to
track this bug down yet...

The behaviour of the usb-storage stuff is unchanged from 2.4.7, but the
visor definitely did work with 2.4.7, where it doesn't now.

Thanks,

P.S. please CC me as I am not on linux-kernel.

But the usb-storage code did change from 2.4.7-2.4.9 while the visor
code hasn't :)

So I'd try unloading the usb system (or rebooting if it's compiled into
the kernel), and just trying a visor sync without running the
usb-storage code to try to narrow down the potential problem.

thanks,

I tried the visor first, and saw this behavior.  (without even insmoding
the usb-storage driver)  I tried it several times, with the same
results.  Only this morning before sending my message did I try the
usb-storage to see if it was broken too.

I've rmmod'ed everything and re-insmoded everything (except usb-storage)
with the same results.

Maybe related:
Why would /proc/bus/usb be always empty?

I'll reboot to 2.4.7 again when I get home tonight and try it.

And usb-storage worked?
Maybe it's a problem in your visor.  Does a soft reset of it fix it?

Did you mount usbdevfs there?  See http://www.linux-usb.org/FAQ.html#gs3

Yes.  *sigh*  Never again will I buy this palm/visor volatile RAM
non-rechargable B&W no memory protection piece of crap.  I wonder how
well those Agendas work...

Thanks.  Sorry for bothering you.

No.  I thought that was no longer necessary?  Anyway it works now.
