Digispark not recognized on Windows 8.1

[exeng]

Did a clean install of the Arduino 1.6.5r (latest) IDE. Installed the Digistump boards per wiki instructions. Try to upload start sketch and get USB device not recognized. I'm pretty sure this board has worked in the past on my old Win 7 system with digistump addons/driver and older IDE.

At the time Windows complains a very faint LED near pin 3 comes on. Power LED near edge of board is on.

HELP!

UPDATE: Repeated the recommended install from Wiki on my Windows 7 PC and my Digispark works, so I know it's not bricked or bad. So why I cannot get the Digispark to be recognized and uploaded on my Window 8.1 based PC.

Does anybody have a clue? Digistump support I need you.

It's working on Win 8.1 this morning. Must of needed a PC shutdown and reboot for everything to fall into place. Wish I could tell everyone how it was fixed but don't have a clue. Driver issue I guess.

Good to hear it working, just seeing your thread.  It worked well on win 8.1 last I used it,  as long the cable was good. Something (overcurrent) may have shut the usb port off that resets on restart.

  Arrrrrgh, here we go again... The previously occupied USB port that I reported working will not recognize my Digispark on Win 8.1 (Works on Win 7). It is as if the ports are dropping out for use with Digispark.  I'll get it to work (through shear luck) and then days or weeks lately after not using it, the Digispark is not recognized on the USB port. I'm at my wits end. There must be something deep in 8.1 USB support the needs a big hammer reset. Extremely frustrating. Oh well... If anyone has a clue or solution to this please post. Otherwise, I guess all my Digispark development will be on my Win 7 laptop (another reason why I not going to update to 10 until forced).

Sequence...
1. Write a sketch
2. Upload (Digispark out)
3. Insert when prompted
4. USB device not recognized. Upload times out.

Any help appreciated.

I have the same behavior on my Win8.1 - "USB device not recognized" pops up frequently.
However if I just unplug/plug the digispark again when this happens, upload succeeds the next time ...

Tom, No such luck here for me. Tried to reinsert the Digispark and still nothing. It just times out.

Do you use an USB-Hub?
I have connected mine directly to the front USB, because I remembered that e.g. my old scanner was not recognized until I connected it directly to the PC, while it had worked fine over the hub on Win7.

[exeng]

I've tried direct, through a extension cable and through a non powered USB hub. I tempted to acquire and try an externally powered USB hub or make a special USB cable that does not connect USB + with the Digispark getting power from VIN. I tried powering the Digispark through VIN but this of course meant that it was already on before plugging in to the computer. Hence the idea of disconnecting USB + and switching VIN externally. Worked before, what could have possibly changed? I guess I'm trying explore that possibility of marginal power. Wish I knew how D- and D+ were behaving.

[exeng]

Well... I tried the special cable with no luck. Also tried pulling up reset. No luck. I doubt that it is power related and looking more and more like something specific to my Win 8.1 system... either drivers or ports. For the life of me I don't know why it worked before, albeit on a decreasing number of ports as time went on. Wish I had a second 8.1 system to try. But for now I'm done, cooked, baked... Digi stumped. I cannot get my Digispark to be recognized on my 8.1 system. I've tried many online suggestions for device not recognized error 43 and still no luck. Thank goodness I still have a working Win 7 system.

Bummer - not sure if the same applies to your findings - but Digistump, IIRC, said the tool used to create the Win7 driver is different from the one used to create the Win8 driver.  It came up when I was seeing my PRO act differently between the two - but I haven't looked lately.  I did plug in and program my PRO on my Win10 box that was Win7 - now using 1.6.5.  I've put my Win8 box to Win10 too but not tried my PRO there.  Given the PRO I didn't spend much time with the Original, in the last months I moved from PRO to Teensy and waiting on the Digistump ESP8266 OAK to ship.  But if you could try on Win10 it might work

I was seeing real diff's as my PRO's were working on Win8 to some degree but looked bricked needing new bootloader and not running right programmed under Win7.  I sent those PRO's to Digistump for diagnoses, but not gotten feedback that he found anything with his time going to OAK.

Defragster,
Thanks for morale support and the sharing of your first hand experience. I'm a little reluctant to upgrade to 10 on either machine. Too many horror stories for me to be comfortable at this point. I have to much invested in apps to take a chance. I've already had to upgrade many of them to run on 8.1. So I will hold off for now even though it's "Free". Seems the upgrade either goes smoothly, or turns into days of frustration and lost capabilities. With my luck it will be the latter. As long as I can use my Win 7 machine for digisparks, I'm OK, even if it is not my preferred setup. Haven't tried my  Digispark Pro on 8.1 lately. I probable should just to see if it still works. Also have a Digix which worked but haven't used it lately either, and also have some Oaks ordered.

Pains me not to know the underlying problem but I'll just have to let it go.

   Good luck with the PRO - if you can get that to work you'll know something is right with the world . . .

My Win 10 was fun with the Pro - I think I tried a USB sketch and it failed - but blink or something other worked, went back to Teensy as I want to be ready to talk serial to it when the OAK ships - but it was nice to program from 1.6.5 in my common environment with just the 'ADD BOARD JSON' and no special build tree!

As far as Win 10 - I have 4 Win 10 machines of my own upgraded 4 year old Netbook (weak and it works better than Win 8 did!) and a laptop and another laptop that is about that old both from Win 7 - then there is a desktop I built last year that was Win 8 went to Win 10.  All no problems - except vid driver on this laptop seems to have some issue that has taken it down about 3 times in 5-6 weeks.

My current task/distraction in life is helping other with their computers - lets me stay home - I had one computer not take Win 10 - it was so infected before it was amazing I got it to run at all.  There are at least 12 more - probably 15 as I stopped counting - I've done for others - not one problem from Win10 after it was done!  About two had to have the Upgrade run a second time to work.  I downloaded MSFT ISO's ( one does x32 and x64 ) - one each for HOME and PRO.  Netbook was an online preview install and my Win 7 laptop pulled the bits down - all but maybe one other I ran from the ISO CD to avoid repeat downloads.  There is risk for sure - but I've seen no issues and have two more in the shop to finish - one is brand new out of box not powered on yet.

Win10 seems a decent service pack for Win7 and an upgrade for Win8.

I did have one 2 year old machine that came not booting Win8 (user got a pop-up (maybe legitimate - maybe not) to upgrade something )- I got it to boot - it had corrupted system files - finally got Win10 to install (Win8 wouldn't even do a factory restore!).  Worked fine for a week - then wholly lost the use of its SATA devices - no HDD - not even a CD ROM boot (Win10 setup or LINUX)- or the one flash drive I tried.  Given all that, I think that machine was toast and can't see how Win10 could have done that.  It was one without a HDD trap door and I wasn't about to 'open a watch' and give any hope of it working when I put the 12 screws back in the bottom.  I had dutifully backed up the user files and restored them for the nice lady on her other computer.
