G-Series Gaming Keyboards

[KrisDK]

Hello. First of all, i would like to explayn my problems with my Logitech G19 Keyboard:

- I can't boot Windows 7, if i dont plug out the keyboard.

- The keyboard sometimes goes in to some kind of options on the LCD-screen, without touching the keyboard.

- The "help menu" keeps spamming my browser (Firefox) or just the help desk on windows, without doing anything. (Only way to fix it is to plug-out the keyboard).

- Sometimes it keeps saying (Loading profile, please do not plug-off the keyboard) And it stands there for hours.

This is some of the problems i experienced.

My computer setup:

Windows 7 Ultimate 64 bit (Newest updates)

Gigabyte X58A-UD3R (ver. 1)

Intel i7 930 (standard clock)

6gb ram

XFX Radeon hd 5850

----------------------------------------------

Things i have tryed to do:

- I have tryed to switch to another USB port - No fix

- Reinstalling the software - No fix

- Updating everything (Mobo, win7 updates etc.) - No fix

- Disabling EHCI (i couldnt find EHCI on my mobo, but i found "usb 2.0 controlling" and disabled that - It fixed the boot problem, but the keyboard is still acting wired with the LCD option popup and help spam without touching the keyboard.

---------------------------------------------

Im just about to RMA this keyboard back, but it seems like it's not a keyboard problem, but a Mobo/system problem. But is there anyone with the same kind of setup as me, that has the same problem or maybe found a solution? I would like to know it!

- Thanks

What we are doing: We are continuing to review customer feedback and see what steps we can take. It does appear that most of the solutions that work have come from resolutions that are external to the keyboard, like changing BIOS settings. We will review all information to determine what can be best done from Logitech's side to resolve this issue, but we believe at this point that the problem lies external to the G19, because if it was internal to the G19, it would affect all computers regardless of motherboard or OS.

Let me just say what a load of complete and utter horse cr#p that is, the issue could very easily be restricted to computers running 64 bit windows and given all motherboard manufacturers of motherboards for i7 processors have to compile to a set of standards when producing thier boards its pretty easy to connect the dots that there is infact a common thread here. Clearly the USB3 boards are all going to have the same standard architecture regardless of manufactorer. Clearly you guys know its a memory buffer overload issue on the usb bus, do us all a favour and either a) fix the issue or b) admit your company made a mistake and give us our money back

Hi all,

First of all, i trust Logitech products only. Its who i started off with and its who ill end with.

PC Specs:-

OS - Windows 7 Pro 64x

Motherboard - Gigabyte GA-H55M-UD2H Intel H55 (im a noob with motherboards so dont know which part of the name you needed)

Processor - I3 overclocked to 4ghz

I have had my G19 for just under a month now, with no problems till now.

Today i had an issue with my G19 when i started my PC. The LCD screen would come on, then flicker off. The power light was on, the numlock light was on but no keys worked. I tried rebooting, pulling out the wires, a different plug socket but no luck.

I read somewhere that the G19 keys were supposed to work if the power pack wasn't plugged in but the keyboard was connected by USB. I tried that but nothing. I then removed my G35 and MX518 from the keyboard and plugged them into the back of my PC, removed the G19 USB cable and plugged it into the front of my machine.

Wollah, it worked again. I'm not sure if this will help you guys at all, but it seems for me this problem was USB related.

Thanks!

Reaper21-  "Memory buffer" has nothing to do with it. That whole terminology came because the first person to report it decided to give it a name that he thought reflected the issue. Unfortunately, it is not the cause. It's how some USB buses handle EHCI communication while there is a lot of data traveling on the system bus under 64-bit memory addressing. 

When we first got wind of this issue (about a year ago), my entire stock of G19s were cleared out and sent to various manufacturers of motherboards and chipsets that people have reported these issues on. We continued to keep contact and push for resolutions, as it's odd that this issue seems to appear only on select x64 bit systems, and various 3rd party patches have resolved issues on some systems. 

Regardless, our customer support has options to resolve your problem. If you have a G19 keyboard and you're not happy with it, contact your local support team to see what they can do for you. We don't want to stick people with a product they're not happy with, and where possible, the support teams are empowered to take steps to resolve your problems.

CharlesB your talking semanticss                      So CharlesB if you know what the problem is then why haven't you fixed it?

I'm all ears for a solution i'm running a pc with the following specs

Intel Core i7 930

ASUS P6X58D Premium Motherboard

Corsair CMX6GX3M3C1600C7 6GB (3x2GB) DDR3

Western Digital Caviar Black 1TB WD1002FAEX

XFX ATI Radeon HD5970 2GB Black Edition

Samsung P2350 23 Inch Widescreen LCD Monitor

Logitech G19 Gaming Keyboard

Thermaltake Toughpower 1200W Modular

CoolerMaster CM Storm Sniper Black Edition

Microsoft Windows 7 Ultimate 64bit OEM

Pioneer DVR-218L DVDRW OEM

If you say logitech support has the solution to the problem for my system then please by all means post it up here.

CharlesB i've already contacted logitech support and thier solution was to tell me to return the thing, since i'm roughly a 2 hour drive away from the store where i bought the dam thing (bought over the internet so i've already forked out for postage i'm never gonna get back) i'm not wearing the costs of that. You guys have manufactured a dud product, pay me postage (for that matter my hard earned 180 dollars) and i'll quite happily post it where ever you want

Here are my specs

• ASUS P6T Deluxe V2
• Core i7 920
• Radeon HD5870
• DDR3 6GB Corsair Dominator ram
• Windows 7 Ultimate 64 bit
  

Now here is my story.

Bought the G19 today, got home and saw on the USB connector an image saying to install the software before plugging it in, okay great. Start to install the software and it's 3.0.1 when I already have 3.0.4 installed because I own a G15. So I uninstall the current software (reboot) in case it's going to try and 'remember' my G15, and install the CD software of 3.0.1 (Reboot)

Plug in G19 with the AC cable and see LCD light up with the Logitech logo, then I plug in the USB to my PC and after 10 seconds of it saying installing device driver, Windows pops up a message saying USB Device Not Recognised.

This is important because it is quite a different problem to what most people are experiencing.

So I have a $150 keyboard that does not backlight, and the LCD doesn't show me anything, the only lights that do work are caps/num/scroll lock and a light where the power cable/USB connects to the keyboard.

Keyboard functions fine and the multimedia keys work in winamp, G keys however do not work because as it's not recognised by my PC I can't set the G keys to do anything.

Normal keyboard typing works fine though.

So I do some googling and come across these forums, browsed this thread and tried every single solution listed.

• Bios Update
• Windows 7 driver update for nvidia motherboard (pretty sure mine doesn't even come under that but I did it anyway)
• Disable legacy + EHCI support in BIOS
• Mobile phone thing....pointless because my keyboard hasn't actually worked yet....
• Uninstall + reinstall Logitech setpoint + Gprofiler numerous times, even went into regedit and deleted any registry keys that still existed before reinstalling.
• Turn off all services except the 3 logitech ones and reboot.
• http://www.blackberryos.com/forums/resource-center/2038-windows-7-vista-usb-fix-bmerdinian.html
• Turn off windows sideshow
• Try all 8 USB ports on my PC

Any other suggestions?

I'm thinking a windows 7 reinstall but....that's a pretty big thing to do to try and get a keyboard working....**bleep**.

I'll see if I can pick up a USB Y power connector as well but I am doubtful that will do anything.

Otherwise it's RMA, then if that fails....return and never buy another Logitech product again, which is sad because all my mice and kb have been Logitech for the last 6 years.

Edit: Just tried the G19 on my parents Windows XP SP3 Core2duo box and the same thing occured. So I'm going to RMA and then get back to you guys!

[chaos2050]

New Logitech G19 and it works perfectly. So looks like I went to all that troubleshooting for nothing....sigh.

[returnednowwhat]

Ok, since my G19 was still under warranty I have returned to to Logitech for a "credit"... has anyone had any experience with this? They received the keyboard on 6/21/10, and I have heard nothing...

[wizardofbozz]

Just happened on this thread as I was going to give my G19 another chance...but now realize there are Big problems...have a core 17, ga-x58a-ud3r, 12gb DDR3, and the G19 has cost me dearly in time and money. Essentially causes no boot and no key entry into BIOS. All other Keyboards work fine...wired , usb, bluetooth, wireless ...the simpler the better.... what is one to do?

Editing this a day later...definitely has to do with USB ...was charging my phone from G19 ...and had plugged into USB 3.0...changed both,,,,seems to work as it should
