USBtiny and Windows 8.1 Drivers (Lib USB 1.2.6.0)

[phoenixperry]

Now I've gotten used to how the boot loader works, it's really stable and working perfectly. I'm running the neopixel strandtest without hitch after I slightly tweaked it for gemma by changing the dataport. I think at this point the best thing you could do it update the documentation on the main site with all of this stuff. Windows is really pesky with updates and most people will just allow it to update and have these same issues. Those drivers that just blake put up + the .cat file solved my issues. I still have no idea why I had to build the arduino set up the "hard way" so I'd just suggest that windows people do that straight away vs bothering with the auto one and having to redo it. Thanks so much for helping out. We appreciate it. Yep libusb good times!

I'm having a hell of a time getting Gemma installed on my Windows 8.1
I've followed all the directions and still get driver errors.
"Unknown USB device (Device Descriptor Request Failed)"
When I do the "install legacy USB device" it seems to work, but then USBTiny not found, and if I press the reset button to get into bootloader mode, I'm back into "Unknown USB Device" territory.

I'm a pretty sophisticated user, and so far I'm stumped. Please help.

What do you see in Device Manager?

Here's the details from the event log. When I try to update the driver, it says it already has the latest driver.
I had reinstalled USBTinyISP (which I recall was also a bit difficult) so I uninstalled that thinking it may have been interfering. no luck.
Note the VID and PID are messed up.
Device USB\VID_0000&PID_0002\5&14cea3e4&0&4 was configured.

Grr, it looks like it gets even worse, somehow, this installation exercise has now caused my CDC drivers to fail (e.g. my printrbot which uses the teensy/at90 usb cdc inf file.
HELP!

***CORRECTION** it looks like in messing with the drivers, or some unrelated event, the firmware on the printrbot got roached. That's never happened before, but it might be a coincidence... I reloaded it and now the port does show up.

Still no luck with Gemma or Trinket

[adafruit_support_rick]

Can you try a different USB cable, a different USB port, and a self-powered USB hub? Seems like Windows really isn't talking to the Trinket properly. If your other USB stuff is starting to tank, that may point to a bad USB port.

The easiest method to have Windows 8.1 to accept the drivers without issues is to send it to Microsoft so each (32 & 64 bit) can be signed. Would Adafruit be open to that?

[osbock]

I really don't think it's a bad USB port. Everything works fine in linux
Trying a system restore now, though that's never done much for me...
If I have to reinstall windows, I'm going to be grumpy for weeks....

[AnneBarela]

Windows 8.1 enforces installation of signed drivers unless booting into a recovery mode and temporarily disabling the signing requirement. And some Windows 8.1 machines have issues booting into this mode or using the drivers loaded in unsigned mode.

For now, I would suggest trying to find a different operating system to use.

It is hoped that a digitally signed set of LibUSB drivers with Adafruit's IDs can be generated in coming days, no ETA promised.

The beta driver is now linked in the Trinket forum, at the top.

i'm in the same boat as the screenshots posted by "osbock"
has a resolution been found?

[adafruit_support_rick]

Have you tried the signed driver?

Thanks to all in this thread. I was having the same "Device Descriptor Request Failed" problem for my Adafruit Gemma v2 on Win 8.1 x64.

After moving to a USB 2.0 hub (embedded in my SIIG keyboard http://www.amazon.com/SIIG-JK-US0412-S1 ... 0039TQH4M/), the board was seen as a Trinket in Device Manager.

Updating to the signed drivers, they showed up as USBtiny, but with an error (yellow exclamation point).

After resetting the Gemma, I'm in business!

Hey guys, Im sorry for my dumb question, but i got stuck witk my Atinny 2313, when I connect it to my computer the computer only recognizes an unknown device, then i try to load drivers manualy, but when i do this, windows only responds that the best drivers are already loaded on it. But it is still an unknown device and it dosent work... Im using an older version of the USBtiny, because i made it myself on a protoboard...
If you have any ideas please help me.

Thank you,
Zan

Try uninstalling the driver, then install the USBtiny driver manually
