Powering up a new GS 911 USB Version, what powers the LED status light?

 I'm at a loss here. It's a long story but, I just received a replacement GS 911 USB unit and I got it all registered with Hex Code and I'm having an issue. The unit seems to be functioning just fine. All the scans and tests of anything I ask for, like testing brake lights, head lights, horn, turn signals etc. all seem to be working just fine. I also did a test of the interface itself and that turned out perfect.

But, the problem I'm having is, the LED status light on the unit itself, NEVER LIGHTS UP! It didn't on the last unit either which is why I got a new one. Now, this one does not light up either. I have searched the frequently asked questions and all I can find is that the LED status lights presents with certain patterns at given times. But, there is ZERO information as to whether or not the bike powers the GS911 LED status light, or the computer powers it up. The Beemer shop tech advised me the computer powers it up. I have tried multiple USB cords to try and power it up but, it's a no go. So, can I ask, for those of you with the USB version, what EXACTLY powers up the status LED on your GS911 USB version?

The GS911 is powered from the diagnostics socket when plugged into the bike but not plugged into USB & is powered from the USB when not plugged into the bike, obviously there is power from both USB & diags socket when plugged into the bike & diagnostics socket

What you seem to be asking is how the LED is triggered rather than where it is getting power & as per the info below it is triggered by a firmware routine in a more intelligent manner than a simple on/off to show the status

The LED power/status indications are documented on this page https://www.hexgs911.com/connectors-buttons-and-lights/

Since you have the USB model the WiFi LED info is not relevant

Wayne,
  I very much appreciate you getting back to me with an answer. So, from what you're saying, the power status of the LED on the GS911 can be triggered by being plugged into the diagnostic socket on the bike, or, it can be powered by the USB plug from the computer, correct? But, not both. Well, this is where the problem is. I have a brand new GS 911 USB version and since my bike is a 2015 BMW GTL-Exclusive, it has the round diagnostic plug. Sooooo, that means I had to buy the short *Round to Rectangle* adapter cord/cable to plug into the rectangle port on the GS 911.

 Well, on the last GS911, I didn't get any LED light when plugging in initially to the bike. I didn't get the LED to light by plugging into the USB port from the computer either. That GS 911 was also only a month old.

So, I got a replacement for it. Now, I have another brand new one and, as stated, I have no power up LED and no continued flashing, nothing. But, the unit does recognise the bike, and performs as it should. I can do scans and tests and fault readings and clearings and service resets and more. I just don't have anything that tells me that unit is powered up.

As for the link you sent, yes, I've gone to that one many times and while it does say that, that particular LED is the power status and states just how it's supposed flash, nowhere on that page, does it state WHAT powers that LED.  So this is why I asked which way is the unit powered up, the bike or the computer? Mine is not powered up by either one. Not sure which way to go now. Thanks again.

The GS911, like many ECU's on the bike (V-Bat & V-Ign) it is designed to handle receiving power from 2 sources simultaneously when in operation & triggering is handled on the other leg of the LED to give the flashing or solid lamp indications, you will need to look further than the GS911 as you have had the same issue with multiple units, move past simply thinking in terms of what powers the LED, think in terms of what operates the LED

There should not be an an adaptor cable issue assuming you have the Hexcode adaptor, I have round pin GS911 & the other Hexcode adaptor to use it on the new models with OBDII diags socket, I have had no issues with the adaptor cable

What is the PC/Device you are plugging into & what operating system ? W10 ?, are you plugging in directly or via a USB hub ?

What GS911 PC Sotware (the old GS911 App or the new GS911 Diagnostics App) & what version are you using ?

Your model is K48 - K1600 GTL Exclusive US market with BMS-X so diags socket is 4 wire, V-Bat, Earth & CAN-L, CAN-H

The pin out should power the GS911 without issue, does the PC App Auto Detect the bike before doing an AutoScan ?

WayneC,
 Again, thank you for your assistance here. I'm quite sure you're over my head in when things get any more complicated than a positive and negative for turning on and off a light bulb. When you state think more of what "Operates" the LED vs what powers it, forgive me for my ignorance but, isn't that the same thing? To me, either way, you're turning it on or off or, flashing it. That's my simple understanding of how things like that work.

There should not be an an adaptor cable issue assuming you have the Hexcode adaptor, I have round pin GS911 & the other Hexcode adaptor to use it on the new models with OBDII diags socket, I have had no issues with the adaptor cable

Well, yes, I do have an adapter cable but, it's an Amazon one. And when I had trouble with the prior GS911's lighting the LED, I had no way of telling if the adapter cable I purchased, might have been a bad one or not so, I ordered and received another one. That new one makes no difference. The older, and this new GS911 still shows no LED when plugging into the bike, with either the original or newer adapter cables. Again, I have no idea on whether or not possibly BOTH of those cable adapters are the issue.

 Would or could that be possible, two adapter cables being bad? Who knows. To this end, I've thought of ordering an adapter cable directly from the Beemer Shop to see if maybe this could be the answer.
 But, according to the tech at the Beemer Shop, the new GS911 I now have in my possession, was pre-tested prior to shipping, and a note was placed in the carton stating that it works. Upon receiving it, I immediately took it out to the bike and plugged it in. NOPE no LED. I changed adapter cords/cables, NOPE no LED!

 I called the tech at the Beemer Shop and he stated that Ted tested it. He also stated that the GS 911 is ONLY powered up by the computer, NOT the bike side. Hmmmmm.

So, with that being said, I thought I'd try various USB to printer port cables I have, just in case, the cable that was sent with the GS911, got messed up somehow. I have three other USB to printer port (the type of end on the GS911) and, nope, no change, NO LED, with any cable hooked to it, from any source.

What is the PC/Device you are plugging into & what operating system ? W10 ?, are you plugging in directly or via a USB hub ?
As for what PC/device, it's a brand new, 2 week old, HP 15" lap top. I'm plugging directly into it with the USB cord from the GS911. And, this is the new Windows 11 system. When I first tried to register/license this new GS911 on this new PC, apparently the 30 temp version of McAfee Virus protection, didn't like an intruder such as the registration process of the GS911 and the Hex Co[de system. It would reject the process stating that it prevented a virus. I tried it a few times and, each time, the little McAfee box would pop up and stop the registration process.

Sooooo, I grabbed my older lap top and, completed the registration process on that one without issue, since I have a different virus protection and, that computer is operating on Windows 10. Nope, no hub involved.

What GS911 PC Sotware (the old GS911 App or the new GS911 Diagnostics App) & what version are you using ?
I am using the new GS911 Diagnostics version, the one intended to be compatible with W7,8, and 10. It doesn't say anything with being compatible with W11.

Your model is K48 - K1600 GTL Exclusive US market with BMS-X so diags socket is 4 wire, V-Bat, Earth & CAN-L, CAN-H

The pin out should power the GS911 without issue, does the PC App Auto Detect the bike before doing an AutoScan ?
I'm glad you mentioned the "pin out" thing. Now, again, my version of electrical knowledge is for the most part, cave man. I'm under the thought that, if the GS911 LED is supposed to be powered up by diagnostic port and the adapter cable, then my thought would be, ONE of those four wires, would hot or, 12V or something of some voltage that would be enough to power the LED. Again, that may be way too simple of a description of how things work.
   But, if that would/could be the case, then which of those four wires might be the "hot" or 12V or lower voltage wire that I could l check for power? I didn't and still don't want to start probing any of those 4 wire/socket/ends to find the potential 12V without at least trying to understand that I wouldn't cause damage to any of the bikes electronics by probing. Are you seeing what I'm asking/saying?
 
Again, I most sincerely appreciate your assistance here in this matter. There are a couple of schools of thought here. One, since the new GS911 seems to be functioning in all aspects of operation, i.e. scanning, me doing tests of the brake lights, turn signals, and any other function of tests, and, doing an AUTO DETECTION of my bike, I could simply just not worry about the non-op LED power status light. Or, two, look at the situation that, this is an expensive tool, and the LED *should* work.

In my eyes, if I were to choose option ONE, and just not worry about the LED, if at sometime in the future I go hook up the GS911 and I get NOTHING on my computer screen, no scan, no recognition of the bike, nothing, and I have no LED working, I will not be able to tell just where the problem lies since I had no LED from the git-go. See what I'm saying? This is why I'd like it to work.
