Re: Solved: USBtinyISP: USB device not recognized on all com
Had the same issue as the last user described (austind).
My system is Win7 x64, running on i7-4770 with 16 Gigs of RAM.
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.
After a hour of juicy curses finally found a solution that worked for me.
It turns out that VMWare's "VMware Workstation Server" service is the problem.
By changing its start up mode from "Automatic" to "Manual", and stopping the service, the USB driver is loaded AND USBTinyISP is again working.
So i guess it's some lousy little checkbox somewhere in the VMWare's configuration.
Now, since that might not be the problem with you, try this, as that's the way i found my solution:
1. Restart in Safe Mode
2. Plug the USBTinyISP and install the driver. If everything is OK, your Windows should be able to recognize it (still, you cannot use it under safe mode)
3. Restart normally and open msconfig
4. Under General Tab, chose "Diagnostic startup" click Apply->Ok and restart your machine normally.
5. After loading Windows, connect USBTinyISP and it should be recognized without a problem.
6. If step 5 is working, run services.msc and write down all the services that are currently running (just to have them as reference for later)
7. In msconfig, change back the startup mode from "Diagnostic startup" to "Normal startup" and restart normally
8. Run services.msc again and start stopping the currently running services, by starting with the least important ones (google updaters, printer/scanner related, , etc. c*ap) and skip those you write down at step 6.
Eventually you will pinpoint the bastard screwing your USB devices.
I've register on the forums to post (in bad English, but oh well) this solution only, so i hope it help someone.
