USB: Wacom Graphire mouse wheel does not work anymore

[karl.gustav]

Hi,

I've a Wacom Graphire USB. I tested the test11-pre6 kernel with my
Graphire USB. The scroll whell of the Graphire mouse does not work with
the last test kernels. The last kernel supporting the wheel was
test11-pre2, I
think...
                 
I used the IMPS/2 compatible mouse emulation of the wacom driver
(/dev/input/mice).

Otherwise I have a general USB problem with my SMP box. Under heavy load
the Graphire stops working and the USB is dead. Unload and reload of the
USB modules does not help. No interrupts are registered anymore. I tested
with usb-uhci and uhci, too. The same result.

Is it possible, that there are some interrupts eaten under high load and
the kernel (or USB driver) does not handle this correctly? With older
kernels
I had promblems with APIC errors and one of the CPUs stoped working and
some seconds or minutes later the whole system was frozen. But this
problems
have gone with the latest kernels. The USB problem seems to be the last
one of
this kind (for me).
 
    Karl

PS: Is there an OHCI compliant PCI USB controller card available? I'm
    using an UHCI type with a VIA chip.

 Don't do that. It's evil. Use the xinput driver instead.

 Yes, Belkin makes one. Originally it was designed for a Mac but it
 should work under linux i386, too. The name seems to be "2 Port USB
 PCI-Card"

Uh, it's not *that* bad ... (what's good: better noise filtering than the
Xinput driver I'm using (xf86Graphireusb.so, June 15, under XF86 3.3.6);
what's bad: only provides mouse).

But anyway, the mouse wheel is also unavailable with the Xinput
driver.

Hm, there is no stable xinput driver available for XFree 4.0 and xinput
does not support the wheel, too :-(

 Actually XInput supports that sort of information but probably the
 XInput driver doesn't. Unfortunately I don't have a Graphire, just
 a Intuos right now and no airbrush available to test that.
