USB polling rate 1000hz does not work (only 500hz)

I have 3 mouses, a Zowie FK2 mouse, a Steelseries Sensei Raw and a Razer DeathAdder 3.5G mouse. All of them fully support 1000hz USB polling rate (it's one of their main selling points) and I have already tried them successfully (1000hz) on Windows 7.
Following the Arch Wiki guide, I successfully enabled 1000hz mode with usbhid module.
$ cat /sys/module/usbhid/parameters/mousepoll
1
$ systool -avm usbhid
Module = "usbhid"
Attributes:
coresize = "48595"
initsize = "0"
initstate = "live"
refcnt = "0"
taint = ""
uevent = <store method only>
Parameters:
ignoreled = "0"
mousepoll = "1"
quirks = "(null),(null),(null),(null)"
Sections:
.bss = "0xffffffffa005e960"
.data = "0xffffffffa005e000"
.exit.text = "0xffffffffa005b169"
.gnu.linkonce.this_module= "0xffffffffa005e700"
.init.text = "0xffffffffa0044000"
.note.gnu.build-id = "0xffffffffa005c000"
.rodata = "0xffffffffa005c080"
.rodata.str1.1 = "0xffffffffa005c8c4"
.rodata.str1.8 = "0xffffffffa005cd18"
.smp_locks = "0xffffffffa005c7d8"
.strtab = "0xffffffffa0046f80"
.symtab = "0xffffffffa0045000"
.text = "0xffffffffa0054000"
__kcrctab_gpl = "0xffffffffa005c050"
__ksymtab_gpl = "0xffffffffa005c030"
__ksymtab_strings = "0xffffffffa005da40"
__mcount_loc = "0xffffffffa005d7b0"
__param = "0xffffffffa005d750"
__verbose = "0xffffffffa005e200"
So according to the above outputs usbhid is already running with 1000hz (1ms polling rate).
But when using evhz which measures the HZ both with the DeathAdder and the Zowie FK2 I get this:
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
event0: latest hz = 500 (average hz = 500)
When I use the Steelseries Sensei Raw setting 1000hz using the sensei-raw-ctl, evhz reports 1000hz successfully.
So what is going on? Why the two other mouses are stuck on 500hz and can't get to 1000hz?
I now only use Zowie FK2 which is much better than the other two mouses and I need 1000hz because 500hz has microstuttering which impedes my gaming use.
Is this a bug? How can I fix this?

In the end I found out that this maybe is just a reporting bug with evhz utility, the mouse runs in 1000hz correctly. I tried dimr.exe with WINE and it reports 1000hz correctly.
Though I find it funny that when I tried mousepoll=2 (500hz) and mousepoll=4 (125hz), dmr.exe still reported ~1000hz. Now I'm not really sure if it is a reporting problem with evhz, or with dimr.exe.

My touch pad does not work only when using Safari browser. The screen was grey. Help!

My touch pad does not work only when I use Safari browser online. The screen was grey. No matter what I do, there is no reponse. Only the web address box works. What is this problem? I can use App Store and everything else fine.
Someone please help.
Thanks

I would try:

- Go to Settings>Safari and delete cache, history and cookies.

My Pokerist app sound does not work, only with headphones....can anyone help me? Thank you

My Pokerist app sound does not work. It will only work if I have head phones on. All other sound works, songs, video etc. I deleted the app, then installed again still no sound. It is not the app because I also have a IPhone and the sound works on Pokerist. If anyone can help me I would appreciate it.

Bought iphone4 and the microphone does not work only if we use in speak mode. How is it possible to fix

I bought two iphone4 in Miami and one of them appared a problem that the microphone does not work in normal call only if i use the speak mode. I am living in Manaus - Amazonas - Brazil and we do not have an apple store to complain it.
Question.
How is it possible to fix this problem ?

Unfortunately, the warranty is NOT international. You will have to send the defective phone to someone in the U.S. and ask them to take it into the Apple Store for replacement, then have them ship it back to you. Apple will not accept the International shipment, nor will they ship a replacement phone out of the country where it has warranty coverage.
There are 4 carriers in Brazil who sell the iPhone, including one which sells it completely unlocked. You probably would have been better off to purchase them there if that's where you live.

Time Machine Configuration of USB Backup Device - Device does not work

Hi there,
my issue is that it appears that I'm not able to successfully partition / initialize / format or whatever my external USB device (Trekstor Datastation 300GB NAS) to work with Time Machine.
Time Machine wants to prepare the drive which I accept and then it doesn't do anything for a long time (appears process hangs). After some time it will state that it failed or I manually kill the process as it hangs.
After that I can not use the drive anymore at all since partition table seems broken. After using fdisk on Linux I can get the drive working again by creating a FAT32 partition.
I also tried to use fdisk on OS X and I could get it partitioned with "fdisk -a device" but even after that Time Machine does not accept the drive.
All options like delete, partition, repair etc. using Disk Utility.app result in broken drive.
I also tried with another (standard non NAS) USB device, same issues.
I also tried booting from Install DVD and used that Disk Utility.app. Same result.
I tried many different combinations now and I'm really lost. Although I'm quite new to Mac OS X I have quite some experience with Linux and Windows and it's not the first drive I have to initialize.
Anybody has any good idea? Are there tools that help analyze the issue?
It appears that the app can remove the FAT32 partition and then it stops. Lights from USB device turn off. No working sound anymore on drive. Process gets listed as "not responding". Even after 30 min nothing happens anymore.
Thanks for any comment that might help out here.

So I finally sorted it out. After a couple of further attempts using OS X and different tools I started looking for a software which could do it using Linux. I haven't found anything. So I looked further for something using Windows.
Although I don't like it I have to admit that MacDrive 7 on Windows XP did it. It ran just perfect, done in 2 minutes and drive usable for Time Machine without any further issues. It worked even with the Trial Version and I really consider to buy it for any potential future need. I think the only disadvantage is that I have read that MacDrive can only format the entire drive, which I wanted to do anyway. However, some might want to have a separate FAT or NTFS partition on it, I think in that case this might not work.
However, if anyone should have the same issue try MacDrive 7 on XP.

Replacing the LCD it's quite simple, just requires a lot of work and the correct tools, keep in mind that doing so will void your warranty and your phone might not be waterproof after this.

Latest USB Image (2009.08) does not work

So I downloaded the archlinux-2009.08-netinstall-i686.img USB image and UNetBootin for Windows, and it did not install the image correctly to my USB drive.
I have plenty of space (it's an 8GB drive), and I have successfully put a number of other distros on the drive, and all while using UNetBootin on Windows.
I even tried installing it on my linux machine using the dd command and the instructions on this page: http://wiki.archlinux.org/index.php/Ins … _USB_stick
Anyone else having these problems?
Can't have fun trying Arch out if I can't even put it on my install media

I tried the April 19th image, which according to what I read replaces the .img USB image. It worked with unetbootin, but once I booted into it, there was some error (can't remember it, gonna have to try it again to see the actual error).

Can't remember, didn't write it down...but it is inconsequential as the image wasn't working with any method.

Two finger scrolling does not work ONLY on Firefox

This just started today, suddenly my two finger scrolling doesn't work but only when I'm in Firefox, offline and on Safari and Chrome it's fine. Restarting Firefox only fixes it for a few minutes, then it stops working again. All of the suggestions I've found that I've tried haven't worked, please if anyone could help and also break it down fairly easily, I'd really appreciate it.

<blockquote>
Does this happen in Safe Mode?
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
:[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
</blockquote>
The same issue happens on Firefox 35.0 running in safe mode, Mavericks 10.9.5, both with Magic Mouse and normal standard mouse...
It's unbeliaveble this issue is going on since more than one year ago, I can find people complaining about it since December 2013!
Oh, one more thing: I don't have a two finger swipe configuration, I have single finger swipe, so the actual problem is about scrolling the page in itself (considering I've tested it with a normal standard mouse as well....).

My apple tv does not work. only apps showing is computer and setting. I did not update my apple tv. just turned it on and all the apps weren't there.

how can I fix this? all my apps disappeared! i tried restarting, location, network, unplugging, fixing HDMI....all brings me back to two apps on the front.

Welcome to the Apple Community.
Assuming this is not the first time you have used your Apple TV
You might try restarting the Apple TV by removing ALL the cables for 30 seconds.
Also try restarting the router. (Also try removing it’s power cord for at least 30 seconds)
If the problem persists, try a restore, you may want to try the previous procedures several times before doing this.
If restoring from the Apple TV doesn't help, try restoring from iTunes using a USB cable.
If this is a new Apple TV, in addition to trying the above, it may also be that your network router is not allowing access to the timeserver, check that your router allows access over port 123.

DB adaptor polling, edited sql does not work correctly

Please considet the following table
BPELProcess State
BPEL1 0
BPEL2 0
My DB adaptor is polling on this table to check for the state 0.after reading it changes it to 1. and invokes the bpel process 1 .Bpel1 invokes another process which changes the state back to 0 .
DBAdaptor polling freq is 2 min
DB adaptor SQL is
SELECT BPELPROCESS, STATE FROM INVOKEDMADMPKG WHERE (((BPELPROCESS = BPEL1) AND (STATE = 0)) AND (ROWNUM <= 1)) ORDER BY BPELPROCESS ASC FOR UPDATE NOWAIT
but i used to see 2 instances every 2 minutes,i should see 1.
when i deleted the 2nd row from the database table then it started working fine FOR SOME TIME and thenm the issue returned.
I see twp bpel instances every 2 min
Why cannot i pol on condition where BPEL PRocess =BPEL1 and State =0
Is there a way to accomplish this

DB adaptor ... check for the state 0 ... changes it to 1 ... changes the state back to 0 ...BPEL will allways work in a transaction... So the change to 1 in the middle of the transaction doesn't make much sense, it will never be visible by other threads...
I'm not sure what you're trying to achieve with that construction but I would say DbAdapter/Bpel wasn't designed to work like that... The results will be unpredictable, as you noticed yourself on your tests...
If you need a BPEL to be invoked every two minutes you may have a look at using a scheduler...

Google page loads but does not work, only works in Private Browsing

Google page will not search anymore unless I trick it into working for me !!
If I enter search term it simply won't budge, but sometimes if I click on images then back to regular it will pop up the results. That doesn't always work though.
Another way it works perfectly is in private browsing mode.
Google is refusing to work with Firefox and I have updated Firefox twice now.
Other sites work fine.
I also have complaint google forced me into a google account when I made a youtube account and this problem may be associated as it happened same week. Also google signs me into google whenever i sign into youtube, that really pisses me off as i had no idea it was doing that until I noticed I was "signed in" on a google page I opened. Anyone could have accessed my google/youtube acct. and password while I was unaware of this from that computer. Now I open google and sign out there after i sign in to youtube !!! What a piece of work google is for doing this crap.

Is the enclosure locked? External drives won't mount if the enclosure is locked, typically.

I am a web designer and I updated to firefox 19 and now my popups on my site does not work only in firefox 19. what has changed in firefox browser?

I have a popup banner and also popup links that I have for sign-in or request info on my site using JavaScript, It always worked fine until I updated to Firefox 19. On other browsers there are no issues.

If you use specific JavaScript libraries then make sure to use the latest versions.
