[Qemu-devel] [PATCH 0/3] usb-linux do not send unnecessary GET_CONFIGURATION (v2)

[Hans de Goede]

Hi All,

This is version 2 of this patchset, it changes the first patch in the
series to not use the devpath sysfs attribute as that is not available on
kernels < 2.6.33

The other 2 patches are unchanged.

For those just tuning in here is the summary of the patchset again:
I've begun looking into the current usb redirection support in qemu.

It failed at the first device I threw at it (a usb keychain picture frame),
the problem is that this (el cheapo) device does not seem to grok
GET_CONFIGURATION. This patch sets makes this device work (and stops qemu
from unnecessary sending a GET_CONFIGURATION ctrl msg in general) by
reading this value directly from sysfs.

Regards,

Hans
