Thread: Nanocom evo problem

Anyone had experience with a Nanocom Evo failing to be recognized by a PC by USB? I'm having trouble getting any PC to recognise the Nanocom. Due to some issues I've experienced in the first few days of owning my new shiny, nanocom advice has been to reinstall the firmware. I've had no problems getting the unit into the kernel manager/update mode but the PC kernel manager program just will not switch to recognizing the nanocom is attached so I can update. Nanocom support now tell me it is the PC not the nanocom. However, having tried on 3 computers, a range of USB ports and a couple of cables (known working), I have trouble accepting the diagnosis. Anyone had thus experience or know the tricks?

Have you had a look in System > Hardware > Device Manager (I'm running XP so you'll have to excuse me if that isn't correct on later versions) to see if the Nanocom is actually being recognised by the computer?

cheers

Hello,
I know it sounds silly but is your SD card still installed ?
Usually I download update, open and run the Kernel Manager then once the program is running then I plug in my Evo to the laptop after couple of seconds it sees the EVO and push update. If I plug the Evo before it doesn't see it I am running Windows 7. With my laptop with no SD card in the Evo my laptop doesn't see either, once running Kernel Manager no problems hope this helps..............

Just fishing, no there is no SD card installed. I followed the instructions on the installation PDF very carefully and no luck. I've now tried pulling out the mini USB cable when the unit powers down after showing "kernel bootloader activated" (the words stay on screen for about 40 seconds before the screen goes blank) and putting it back in as another forum suggests doing that a few times can eventually trigger the Nanocom to become attached to the PC. Nope no good either. Do you recall for yours how long the "kernel bootloader activated" message stays visible on the screen before the PC recognises the unit?

OffTrack, yep I've looked there and there is no record or any indication of the Nanocom being connected in any of the 3 PCs, in any of their USB slots or using any of 3 cables I've now tried.

Going slowly mad with a diagnosis of the PC being the problem despite these experiences. Any other clues? RMA is being arranged but I really don't like sending the device back for fixing when I've been advised that it is the PC despite this experience and being told that the fix will likely be a charged fix - I only had the thing for 3 days before it stopped working! (my Nanocom One unit I should point out has been working strong now for what must be about 5 years in the same car and is back in there after a 3 day holiday while I looked to see if the Evo was worth keeping and sell the One. I don't think it's anything the car has been doing either as the One plugged straight in and worked as normal.)

A quick update. Last night I tried putting in an SD card (first time it has had one in) and then connected by USB (again using multiple different USB leads and computers and ports). Every time the Nanocom happily went to the USB storage display screen (showing an image of a SD card on its screen) but every time the computers failed to recognise it as a storage device. Does this continue to suggest it is the PC(s) which are the problem. I'm only continuing to ask here because I've now got the RMA for a return and it states that the service support will give advice to allow tring of every possible option for the customer to get it working before issuing an RMA thus I figure it is only fair that I do as much noninvasive testing at my end also before acting on the RMA. Any clues out there?

Hello,
You must be going nuts..... Sorry I cannot hook up my Evo as on a mine site for the next 3 weeks. Just a couple of things you might have tried already but here they are.
Did you try downloading the firmware and unzipping it more than once ? Maybe straight to the desktop. It might take a couple of times... It might not have any bearing but
Windows 7 has a few problems and some things do not work depends on you machine as downloading map.files I do have a few problems with them takes a couple of times to work.
Have you tried a different Evo on your computer ?
I use win RAR to unzip.
I did read some where you can remove the end of the Evo and reset it cannot remember where.
Hope you get it sorted out......

Thanks Ian. I have tried downloading the firmware manager twice now but not to the desktop. I'll try it again and use win RAR this time to unzip. Yes in one of the user manuals (I think the online version which explains how to upload the firmware), it refers to using either the hardware or software method of upgrading. I looked briefly at the hardware method but that seems simply a mechanism to cause the Nanocom to go into Kernel mode which would be used instead of powering up by USB and selecting the kernel mode. My suggests it is going into Kernel mode (just not seen by the computer) so I don't want to open it to use the hardware method in case that then is suggested later to be the reason for the malfunction. I'll try downloading again tonight. Craig

I did the upgrade by adding the update files to the SD card and then running locally on the Evo itself.

My issues are it works fine in any mode apart from where I want it to work, instruments. Just randomly shuts down or freezes. I'm also reticent to return it at the cost of postage for something I may end up paying to fix thats been happening from day one (but they won't acknowledge apart from "do you want a RMA?")
