USBasp driver for Windows 10

In the past I used USBtiny and USBasp programmers to flash Atmel microcontrollers. Under Windows 10 the programmers did not work, even though Windows 10 seemed to detect them correctly.
It turns out Windows 10 does not use/fetch the correct drivers.
To make things work again most folk use Zadig a tool which automatically installs some legacy drivers typically used for USB programmer dongles.

USB driver installation with Zadig

After the drivers are installed Windows 10 finally detects my USBasp programmer dongle as it should.

WSL on Windows 10

There is a new kid in town when it comes to “doing Linux under Windows”. Up to now there was primarily Cygwin and MinGW. But for a while now Microsoft offers the Windows Subsystem for Linux (WSL). I personally think the name should be the other way around (LSW) but what do I know.

More Windows 10 Issues

On my new Windows 10 installation I came across a few more issues:

LibreOffice did have a nasty offset where the mouse pointer would click way above where it was pointing. The solutions to this bug was to disable OpenGL rendering as described here.

Another bad experience was with VirtualBox which would sometimes boot up virtual machines with corrupted graphics where nothing is readable or even recognizable. The solution to this behavior seems to be to set the “Override high DPI scaling behavior” setting to “Application”; the setting can be found by right clicking on the VirtualBox shortcut/executable > Properties > Compatibility > Override high DPI scaling behavior. I found the solution here.

USBasp in Windows 10

Unfortunately Windows 10 does not accept the standard drivers for the USBasp programmer. The reason is that the drivers have no valid signature from Microsoft (as required by Windows 10).

The only way around this problem seems to be to temporarily disable signature checking and then install the drivers (if you are fine with the security risk). This is described in detail here.

Accessing ext4 partitions from Windows 7

It is a pain in the ass.

Several Windows tools exist which add support for the file systems used in the Linux world.

  • ext2fs
  • ext2ifs
  • linux reader
  • extfs
  • ext2read

See here for a comparison of existing tools.

However, I can not say that any of these worked properly for ext4. Not to speak of ZFS or btrfs 😉
