Libusb0.sys

Matth79 · 03-20-2012, 12:31 PM

Saw this "updated" by the latest Kobo desktop, and surprised to find it is a way outdated version - 1.1.14

Libusb0.sys is currently at 1.2.6 - and has been signed for 64 bit since 1.2...

So I'm guessing that Kobo desktop may have some 64bit compatibility issues, due to the outdated driver.

Just for the records: my frequently updated Win7 x64 has the same driver version 1.1.4 in C:\Windows\SysWOW64\drivers\libusb0.sys and I cannot find any version 1.2.6 via G**gle.

While the driver might be old. I've never seen any messages related to installing an unsigned driver.... For all we know, Kobo might have recompiled and signed the driver.

Info on Libusb-win32 http://sourceforge.net/apps/trac/libusb-win32/wiki
The main SF page http://sourceforge.net/projects/libusb-win32/

Wierder still, in the Kobo\drivers subdirectory, the install-filter32 and install-filter64 files are 1.2.4.0 but the actual files that are used seem to be the 1.1.14 - it begins to look like they half-updated this component, and lucky it works at all the state it's been left in
