Pushing a file to change these settings with usb-modeswitch is not the
right way to fix this. Instead, it's something that should be looked at
directly by the kernel developers and change the timeout if it

Actually delay_use=2 is more than enough to fix things for me.

Since this is evidently hardware-dependent, the minimum value should
better be confirmed by all reporters.
In any case, 2 or 3 seconds is still an improvement against the earlier
kernel default which was 5 seconds, IIRC.

People,
I need *anybody* with the USB 3.0 problem test the ReleaseDelay
parameter.
If that does not work, there is still plan B which is to alter the
default delay_use option with the installation of usb_modeswitch. I
can also let it check the setting with every run.
This would of course
Here is a little HowTo for conducting the test I requested:
There is a list (OR a package) of small config files in
/usb/share/usb_modeswitch.
Pick the one that matches your stick's ID in *install mode* (e.g. if the mode
switch fails or if switching is disabled globally in
Ok, just tried the /etc/usbmodeswitch.d/ test :

All right, I extracted the file 12d1:1446 from configPack.tar.gz, put it in
/etc/usb_modeswitch.d and added the line ReleaseDelay=3000. There was no
difference in the result. :(

There might be a loose relation to bug #992639, where the storage driver

Seems like that. The option delay_use=3 to usb-storage also solves
this.

So, it looks like usb-storage wants to have the device from t+1 until
1+11 (counting from the moment of insertion). usb_modeswitch wants to
detach usb-storage at t+1 (exact numbers differ per chipset,
apparently). This looks like a race condition, caused by various parties
coding in arbitrary
There is nothing orderly about the whole mode-switching business. From
the system's view it's no different than a physical unplug and reinsert
of a device. The word API does not come to my mind at all.
For usb_modeswitch as such, timing is not important - in theory. The
tipping point *should* be
I should note that I do not see any xHCI errors. There's simply nothing
happening, most notably the modeswitch. :)

Could well be. Try increasing the delay to 30 though. If that doesn't
help, we might be experiencing different problems with the same result.
