[SOLVED] Low polling rate of external mouse

Hi all,

I have a problem on my laptop Dell M5030 with external USB mouse: it's polling rate very low.
Value in /sys/module/usbhid/parameters/mousepoll is 8, but evhz util shows that it's polling rate only 10Hz.
ALPS touchpad works fine. Also if I change video driver to vesa external mouse becomes works correctly at 125Hz rate.
Video card on this laptop is Mobility Radeon HD4200. Changing between catalyst and opensource driver didn't take effect.
Mouse works the same with evdev and mouse drivers.

Re: [SOLVED] Low polling rate of external mouse

Bizarre. I'd first look at interrupt conflicts - show some info:

cat /proc/interrupts
dmesg

cat /proc/interrupts looks fine

Re: [SOLVED] Low polling rate of external mouse

Booting with irqpoll option doesn't change anything.

Re: [SOLVED] Low polling rate of external mouse

Seems to be a common problem with the Dell M5030. Some reading for you:

Re: [SOLVED] Low polling rate of external mouse

Thanks you very much. Kernel option acpi=off solved the problem.

Re: [SOLVED] Low polling rate of external mouse

I have same problem on the same laptop (maybe the external mouse is different )
Same dmesg message:

irq 18: nobody cared (try booting with the "irqpoll" option)

And booting with irqpoll has no effect except these lines in dmesg output:

[    0.000000] Misrouted IRQ fixup and polling support enabled
[    0.000000] This may significantly impact system performance

But I don't want to boot with acpi=off. Because with this option I can't set CPU frequency and (very important) USB devices (mouse and keyboard) don't work (don't get listed in lsusb).

Is there a way to have normal mouse polling with ACPI enabled? Or this is a hardware problem?

Re: [SOLVED] Low polling rate of external mouse

Found out that this problem comes only with catalyst driver. With xf86-video-ati mouse works just fine.
