USB error: LIBUSB_ERROR_IO - Windows 10 X64

[Jazzcat6581]

Hi,

When runtest is performed I get USB error: LIBUSB_ERROR_IO

libusb/xum1541:1/20: The handle is invalid.

I am on Windows 10 X64, zadig-2.5 recognises the ZoomFloppy but not the runtest.

I am totally out of ideas.

Any help would be appreciated.

Please check which driver is selected in zadig. It should be the "WinUSB" driver. My guess is that you're still using libusb-win32.

Which version of OpenCBM are you using? If it is something >=
0.4.99.100, then you should NOT install the driver with zadig, but use
the one from install.cmd instead!

This is what Martin meant.

If you are using an older version, then your problem is another one. In
this case, it would be good if you could test the newer one.

Regards,
Spiro.

Thanks Spiro,

Have uninstalled libusb and re-run install.bat and installed the drivers from opencbm.

I am running: opencbm-0.4.99.102

Now when I execute runtest.bat (without the 1541 plugged into the ZoomFloppy)

Found the following drives:
