Function buttons on RK-9100 don't work

post #1 of 14
Thread Starter 
I just purchased and started using the Rosewill RK-9100 keyboard. So far I'm loving it but I have a problem. The keyboard has FN buttons from F1-F12, and while the last 4 work fine the first 8 don't do anything at all. The first 8 include volume +/-, mute, forward/back, and pause/play. The last 4 that work are all related to the keyboard itself and alter lighting so I'm thinking this is a software problem. Before this I had a Blackwidow Ultimate and that had function keys that worked fine. I "thought" I uninstalled those drivers but with Synapse it's hard to tell. Do you guys have any advice I could try? I don't think it's a hardware problem but I could be wrong.

Thanks.

Alright, I managed to fix it! For anyone who might have this problem in the future, I apparently disabled Human Interface Device Access in services.msc at some point. Re-enabling that fixed everything at once.

How you finding that keyboard compared to the Razer one? I'm thinking of making that switch to the Rosewill as well, I now own a Razer Blackwidow Ultimate. By the way can you post some pictures of the keyboard? I've read in some reviews that they find the green backlight of the num lock and caps lock keys a bit too bright, you finding the same? Does it remember the backlight setting on the reboot? For example you put backlight at maximum brightness and then you reboot is it at that same brightness? Thanks

I'll post some pictures and more thoughts later today when I get home. Overall I'm very happy with the keyboard. The backlighting is very similar to Razer's, though with 5 brightness settings if you include off. It also has different lighting "modes" that can light only WASD and arrow keys, or light everything but the numpad. The symbol keys underneath the numbers are also somewhat illuminated unlike the Blackwidow. Most complaints on the keyboard were about the lock keys, which illuminate bright green when you activate them. They're bright, but not blinding like some reviews suggested. I've read many people put a little bit of electrical tape over the LED and that seems to work, so it shouldn't really bother anyways. They can't be adjusted but that's largely because the keyboard has no drivers to download, it's completely plug-n-play. Keep in mind you need to use the second USB cable to get backlighting on. I'll test the backlight memory later.

As for feel, it's got a much smaller footprint than the BWU, and the keys seem just a tiny bit quieter like there's less impact on a full-press. The keys are also a little more rubberized than the BWU, which isn't really better or worse, just different. Being smaller the keyboard feels just a little lighter though it doesn't move around and is still quite heavy.

Honestly for me the biggest upgrade was getting rid of that shiny plastic on the Razer keyboard, and I'm certainly digging the full-matte design. Overall it's a smaller, no-nonsense keyboard that keeps the backlighting and function keys that I liked from the Blackwidow. and feels very well constructed and fun to type on. So far I could easily recommend it.

Thanks for the reply, looking forward to your pictures. I really dont like the shiny plastic on my Blackwidow Ultimate and the blue switches are nice but I think I will prefer brown because I mostly game but I want to keep some tactile feedback. By the way you have the blue or brown switches on your Rosewill ?

Unfortunately all I have at the moment is my phone so the pictures are very good but they should give some idea of the overall look. I stuck with the MX blues, sorry about that. I can't speak for the browns but these are fairly similar to Razer's keyboard, though, as I said, a tiny bit "softer" feeling when they fully depress.







Minimum brightness


Maximum brightness




USB 2.0 ports (one has a bluetooth adapter in)

Thanks so much for the pictures, I really think that will be my next keyboard. I'm sorry to be bothering so much but could you just confirm me if the keyboard remembers the backlight brightness when you reboot ?

Unfortunately it looks like it doesn't. I just did went through a reboot and though all the locks remained in the same position the backlighting itself reset to default. I guess that's another tradeoff of no drivers.
Regardless, good luck with whichever keyboard you end up picking! Upgrades are always exciting. Like I said, I can confidently recommend the Rosewill.
