'No mc-Dongle-Bootloader found'

I just received my McStuff. After reading all of the posts, it's clear that the first thing one should do is update the firmware using the OTA Updater. After connecting the McDongle I could see that Win 7 loaded all of the drivers. But after I started mc-OTA Updater – v1.2.1 the status message was ‘No mc-Dongle-Bootloader found’.
I checked Win 7 Device Manager and can see a COM 60 port, which I guessed was the McDongle. If I unplug the McDongle then the COM 60 port goes away, it reappears after I plug the McDongle back in.
I've tried plugging in the McDongle first, then starting the mc-OTA Update, but no joy. The I've tried starting mc-OTA Update and then plugging in the McDongle. In all case I always get the ‘No mc-Dongle-Bootloader found’ message on the lower left part of the status line.
What really obvious thing am I missing?Like

Hi. I experience the same issue. Win7 64 bit and assigned COM6 for the mcDongle.
Please let me know as wel.
Thanks!Like

My McDongle was initially plugged into my laptop docking station, which means that there's a hub in the USB chain. I just tried plugging the McDongle directly into one of my laptop ports, but I still get the ‘No mc-Dongle-Bootloader found’ message' from OTA Updater.
I tried this because I've had a few USB devices that didn't work well with a hub, but it made no difference in this instance.Like

Mine is plugged directly in a free PC frontside port. I get green LED3V3 lighting up. LEDnRF is off.Like

The mcModules updated fine using the OTA update, don't forget to enter the serial number, remove batery, hit search, insert battery, module is found and you can update.Like

woozer – the issue is that the OTA Updater isn't recognizing the McDongle, thus it never has a change to attempt an update.Like

Do you see an extra com port in device manager when you connect the McDongle?Like

An extra? No, I only see its FTDI com port.Like

From my OP:
I checked Win 7 Device Manager and can see a COM 60 port, which I guessed was the McDongle. If I unplug the McDongle then the COM 60 port goes away, it reappears after I plug the McDongle back in.
Message in the lower left hand corner (also from OP):
‘No mc-Dongle-Bootloader found’ message on the lower left part of the status line.
McThings admins – any idea what the issue might be? Are you looking for the McDongle on all COM ports, not just a limited lower range such as COM1-COM4?Like

We are looking for mcBoot on all com ports.
Can you check in the (USB Serial Port Properties->Property->Device Instance Path) if it has similar string with FTDIBUS\VID0403+PID6015+MCxxxxxx\000

From Device Manager properties for COM60, the ‘Device Instance Path’ is:
FTDIBUS\VID0403+PID6015+MC88FNFA\0000Like

Sounds like USB chip is ok but you got an unresponsive wireless processor. We will send you a new mcDongle as soon as we can.Like

It looks like pin 5 (P0.01/AIN2) and pin 6 (P0.02/AIN3) are have a solder bridge between them. Is this intentional?Like
5d
I removed this solder bridge but the OTA Updater still doesn't find the McDongle. I connected to the FTDI 230X chip using PuTTY @9600 and monitored pin 15 (TXD) with a scope and I can see expected serial data when I press a key in PuTTY. Also, when I press a key in Putty I can also see green LED50 blink with each keypress. The TXD signal also appears on pin 18 of the Nordic nRF51422. The 32KHz oscillator on pins 54/46 of the nRF51422 is alive but the 32MHz oscillator on pins 37/38 is dead. nRST on the SWD header is high.
That's all of the troubleshooting I can do without a schematic or an ARM SWD interface.
Do you have my information needed to send me another McDongle? You should be able to cross-reference my name with my order. I'll also send an email to Thomas E. referencing this thread.Like

Again, can you please help me in restoring the functionality of my mcDongle?
So far, there was no response from your side. Do you read my posts as wel? It seems that you're not, or at least not willing to answer.Like

oops, my post disappeared!
mc-Gyver is on a mission today as the paperclips, tinfoil, rubber bands and chewing gum are missing!
I have sent a private message to you to arrange the replacement dongle. It appears that a very small number of dongles have this issue. Thank you for bringing this to our attentionLike
