Firmware problem

[apv14]

Hello,
today I've used micronucleus.exe to load firmware micronucleus-1.11-entry-jumper-pb0-upgrade.hex as available here https://github.com/micronucleus/micronucleus/tree/master/upgrade/releases. But when i connect pin 5 with ground and place it to the usb, system shows unknow device warning and I can't upload any script nor different firmware to the device. Is there a new windows driver for this firmware version (before the update I was using the default ones that came with the IDE)? What to do?

Thanks for your help!

Oh, yes you assumed right, I've posted it to wrong forum. It should be in Digispark Original, if somebody can move it please.

It's weird you say that the drivers are same for the 1.11 firmware, for me its showing as Unknown Device and I have the drivers installed. I thought its because I am using win8.1 so I installed Digispark Arduino IDE on my older win7 computer, but there is the same problem. I've also tried right clicking the device and selecting update driver-browse my computer-let me pick from a list, but there is no driver in IDE folder that it would be satisfied with.

Unfortunately I don't have the Arduino board, but I have the ftdi serial adapter like this http://r.ebay.com/Loan3z. Is it possible to use it for loading firmware to digispark or do I need to purchase the arduino board?

Yes I have second digispark, the wiki page you were talking about is probably here https://digistump.com/wiki/digispark/tutorials/programming but I dont wan't to risk a failure of loading a firmware to other digispark again so it would be better to order the ISP device.

After searching ISP on ebay i found this: http://r.ebay.com/TjXb18 or the TinyISP you mentioned http://r.ebay.com/HdEbWL Which one is more usable? The larger one has a connector for DC supply which i dont understand as it could be powered from the usb, right?

Thanks for detailed explanation, I noticed that only difference between 10-pin and 6-pin is that the 10-pin has 4 more GROUND's otherwise the available pins should be same. So I've got this one http://r.ebay.com/AAO5mC as its only 2 dollars. Thanks once again for your help.
