After loading Windows, connect USBTinyISP and it should be recognized without a problem.Ħ.

Under General Tab, chose 'Diagnostic startup' click Apply->Ok and restart your machine normally.ĥ. If everything is OK, your Windows should be able to recognize it (still, you cannot use it under safe mode)Ĥ. Plug the USBTinyISP and install the driver. Now, since that might not be the problem with you, try this, as that's the way i found my solution:Ģ. So i guess it's some lousy little checkbox somewhere in the VMWare's configuration.

It turns out that VMWare's 'VMware Workstation Server' service is the problem.īy changing its start up mode from 'Automatic' to 'Manual', and stopping the service, the USB driver is loaded AND USBTinyISP is again working. Microsoft's 'hotfix' -wait-for-it- did nothing ('The update is not applicable on your computer.') except frustrating me about the way they send you a badly formatted URL on the email.Īfter a hour of juicy curses finally found a solution that worked for me. My system is Win7 圆4, running on i7-4770 with 16 Gigs of RAM. I have also tried it on my work PC (Windows 10 Pro, 64-bit) and got exactly the same behaviour.Had the same issue as the last user described (austind). If I do 'Update driver software' > 'Browse my computer.' and point it to the manual Adafruit driver files (available on the link to the guide), I get the same message.Ĭan anyone suggest anything to try? Do I need to (re)install the bootloader itself, and if so, can you point me in the direction of how I do this?Īs mentioned in the comments I have posted on Adafruit's own support forum but got absolutely nothing yet.'Update driver software' > 'Search automatically.' reports that 'The best driver software for your device is already installed'.

Under Device Manager, the board shows as 'USB Device (Device Descriptor Request Failed)'.I'm pretty sure the cable is working correctly (It works for exchanging data on a phone, and I've tried a few different ones).I'm definitely using USB 2 ports, and I have tried it connected directly to the PC and via a USB hub.Following the Introducing Gemma guide I've installed the Adafruit drivers and I'm now trying to get it to connect via USB.Īfter connecting, the board shows the green power LED, but not the pulsing red LED, and Windows shows the 'USB device not recognised' message. I have a V2 Adafruit Gemma from the Gemma starter pack, and I'm running Windows 10 Home (version 3), on a 64-bit laptop.
