Lost Vol UP/DOWN & Mute functions from Logitech Wireless KB through HP Cat5 KVM

I recently updated from an older Compaq 8-Port KVM using discreet Keyboard/Mouse/Video connectors to a new HP 8-Port KVM using the CAT5 cable with RJ-45 connectors and a Interface Adapter on the computer side. I use Compaq EVO workstations running XP Pro Corporate Edition. I also use a Logitech Wireless LX-300 keyboard and mouse and iTouch 222 software. Since changing KVM's, I lost the keyboard button control features for my workstation volume and mute as well as the on-screen volume and mute indications. I have updated to the latest Logitech software and HP firmware on the KVM. Does anybody know how to restore the keyboard control of volume and mute?

I am looking for the hotkey combination for our HP 336044-b21 KVM switch from a iogear KVM?

IOGEAR KVM switches uses Scroll Lock for the hot key. The models of IOGEAR KVM switches starts the letters "GCS". I don't think that your HP 336044-b21 came from IOGEAR.

Anyway, if that's an IOGEAR KVM switch, you may quickly press Scroll Lock twice + Enter (for two port KVM).

Scroll Lock twice + port # + Enter (for 4 port, or 8 port KVM).

NOTE: You need to verify the brand of your KVM switch by referring to the user manual of it.

Thank you and good luck!

Hi, I recently bought a XTENDEX® ST-C5USBV-300 USB KVM (Cat 5/5a/6) extender KWM switch. When I connect it to a HP DC 5800 SFF desktop I can´t get any video signal when it´s connected via a...

Well see Cat5 & Cat6 are different spec's and are wired differently...They have different wires inside the cable. You would be able to use the actual Wires, BUT they will have to be wired to the "Other" standard in the Outlet Jacks. Either that or get one that works on Cat6.

Brought a CS62US and Mircosoft KB with mouse. When USB combo plugged on the left USB, only KB is worked together with switching function. When USB combo plugged on the rigth USB, both KB & Mouse worked...

Unfortunately, this switch has a dedicated port for keyboard that listens for the keyboard keystroke. You MUST plug the keyboard into the dedicated keyboard port on the KVM switch for the hotkeys to work. I recommend putting the mouse that comes with your keyboard to the side, and using another mouse, plugged into the dedicated mouse USB port on the switch. Not the prettiest solution, but some of those mouse/keyboard combos have some funky hardware!

You Compaq unit is proabably a rebadged Avocent like my HP Analogue KVM. To open the menu on that, you simply press the Print Screen button to open the onscreen menu.

Hope this helps.

4-port usb kvw switch #GCS634U

The GCS634U is designed and tested to work only with a standard USB keyboard and mouse. However, most wireless keyboards and mice work with it, but they cannot guarantee any specific model or brand that would work correctly.

As you can see, this KVM switch is a bus powered device (meaning it only gets power from the USB ports of the computers). If the computer cannot provide enough power for the KVM switch to function correctly, then the wireless keyboard will be affected.

You may try using the IOGEAR GKM541RA. It's tested to work with the GCS634U. Or you may also try using a self-powered USB hub (meaning, it has it's own power adapter) and connect it in between the KVM switch and the computer. That self-powered USB hub will be the one that will add up power to the KVM switch and help it to function properly.

Compaq 8-port kvm switch firmware

HP Parts supposedly still stocks the EPROM for this model, so you can try to order it from the HP Parts Store. Check for part 340579-001.

Funny... I was reading about something like this for an HP KVM I' looking at buying... I can't find ANY documentation for that older model. But I did find a forum that gave advisement on how to switch the ports from system to system.

Read this and give it a try:
"Try print screen, then the port number to which you want to switch, then enter.

I copied and pasted it into a text file for myself in case it's the correct method for the KVM I'm going to buy here soon. :)

Perhaps the models are similar enough that it'll work.

Please let me know because I am quite curious to see if this will work. I would imagine that there is a universal standard somehow.

I'll be watching.
